+# Discourse Calendar
+
+Adds the ability to create a dynamic calendar in the first post of a topic.
+
+Topic discussing the plugin itself can be found here: [https://meta.discourse.org/t/discourse-calendar/97376](https://meta.discourse.org/t/discourse-calendar/97376)
+
+## Customization
+
+### Events
+
+- `discourse_post_event_event_will_start` this DiscourseEvent will be triggered one hour before an event starts
+- `discourse_post_event_event_started` this DiscourseEvent will be triggered when an event starts
+- `discourse_post_event_event_ended` this DiscourseEvent will be triggered when an event ends
+
+### Custom Fields
+
+Custom fields can be set in plugin settings. Once added a new form will appear on event UI.
+These custom fields are available when a plugin event is triggered.
+
+### Holidays
+
+See an incorrect or missing holiday? Familiarize yourself with the [holiday definition Syntax](vendor/holidays/definitions/doc/SYNTAX.md). Then make your updates in the `vendor/holiday/definitions` directory.
+
+Generate updated holidays as follows.
+
+```sh
+cd vendor/holidays
+
+# Generate holiday definitions
+rake generate:definitions
+```
+
+Install the plugin and switch to the discourse root(not the plugin directory).
+
+```sh
+# Collect all holiday regions into assets/javascripts/lib/regions.js
+bin/rails javascript:update_constants
+```
+
+### Interactions with Other Plugins
+
+You can use an element of this plugin with the [Right Sidebar Blocks](https://github.com/discourse/discourse-right-sidebar-blocks) component. You'll want to ensure the desired route is enabled via the `events calendar categories` setting. In Right Sidebar Block's settings, the block name will be `upcoming-events-list`, and the params use this [syntax](https://momentjs.com/docs/#/displaying/format/), for example `MMMM D, YYYY`.

+* Issue-163: Add `next_holidays` method. See README for usage (https://github.com/ttwo32)
+
+## 4.0.0
+
+Major refactor with breaking changes! Sorry for the wall of text but there is a lot of info here.
+
+* Fixes issue 144 (loading custom defs with methods). This was the refactor catalyst. Changes highlights include:
+  - Allow for custom methods added via the `load_custom` method to be used immediately as expected
+  - Consolidate and clarify custom method parsing and validation
+  - Change nearly every definition to use new 'custom method' YAML format. See `definitions/README.md` for more info.
+  - Remove `require` functionality when loading new definitions, instead using in-memory repositories. See below for info.
+  - Now loads all generated definitions when `require 'holidays'` is called. See below for performance info.
+* Add `rake console` command for easier local testing
+* Remove or rename many public methods that were never intended for public use:
+  - Remove following date calculation helper methods (definitions must now directly call factory):
+    - `easter`
+    - `orthodox_easter`
+    - `orthodox_easter_julian`
+    - `to_monday_if_sunday`
+    - `to_monday_if_weekend`
+    - `to_weekday_if_boxing_weekend`
+    - `to_weekday_if_boxing_weekend_from_year`
+    - `to_weekday_if_weekend`
+    - `calculate_day_of_month`
+  - Remove `available` method. This was only intended for internal use
+  - Remove `parse_definition_files_and_return_source`. This was only intended for internal use
+  - Remove `load_all` method. This was only intended for internal use
+  - Rename `regions` to `available_regions` for clarity
+  - Rename `full_week?` to `any_holidays_during_work_week?` for clarity
+* Following methods now constitute the 'public API' of this gem:
+  -  `on`
+  -  `any_holidays_during_work_week?` (renamed method, was originally `full_week?`, same behavior as before)
+  -  `between`
+  -  `cache_between`
+  -  `available_regions` (renamed method, was originally `regions`, same behavior as before)
+  -  `load_custom`
+* All generated definitions are now loaded when `require 'holidays'` is called
+  - Previously files were required 'on the fly' when a specific region was specified. By requiring all definitions upon
+    startup we greatly simplify the handling of regions, definitions, and custom methods internally
+  - This results in a performance hit when calling `require 'holidays'`. Here is an example based on my benchmarking:
+    - old: `0.045537`
+    - new: `0.145125`
+
+I decided that this performance hit on startup is acceptable. All other performance should remain the same. If performance is
+a major concern please open an issue so we can discuss your use case.
+
+## 3.3.0
+
+This is the final minor point release in v3.X.X. I am releasing it so that all of the latest definitions can be
+used by anyone that is not ready to jump to version 4.0.0. I am not planning on supporting this version unless a major
+issue is found that needs to be immediately addressed.
+
+* Update public holidays for Argentina (https://github.com/schmierkov)
+* Remove redundant `require` from weekend modifier (https://github.com/Eric-Guo)
+* FIX: Easter Saturday not a holiday in NZ (https://github.com/ghiculescu)
+* FIX: Japan 'Marine Day' for 1996-2002 year ranges (https://github.com/shuhei)
+* FIX: Australia calculations for Christmas and Boxing (https://github.com/ghiculescu)
+* Add dutch language version of definitions for Belgium (michael.cox@novalex.be)
+* Make 'Goede Vrijdag' informal for NL definitions (https://github.com/MathijsK93)
+* Add 'Great Friday' to Czech holidays (juris@uol.cz)
+* Add new informal holidays for Germany (https://github.com/knut2)
+* FIX: correctly check for new `year_range` attribute in holidays by month repository (https://github.com/knut2)
+* Add DE-Reformationstag for 2017 (https://github.com/knut2)
+* Update Australia QLD definition Queens Bday and Labour Day (https://github.com/ghiculescu)
+
+## 3.2.0
+
+* add 'valid year' functionality to definitions - https://github.com/holidays/holidays/issues/33 - (thanks to https://github.com/ttwo32)
+* Fix 'day after thanksgiving' namespace bug during definition generation (thanks to https://github.com/ttwo32)
+* fix Danish holidays 'palmesondag and 1/5 (danish fightday)' to set to informal (thanks to https://github.com/bjensen)
+
+## 3.1.2
+
+* Do not require Date monkeypatching in definitions to use mday calculations (thanks to https://github.com/CloCkWeRX)
+
+## 3.1.1
+
+* Require 'digest/md5' in main 'holidays' module. This was missed during the refactor (thanks to https://github.com/espen)
+
+## 3.1.0
+
+* Fix St. Stephen observance holiday for Ireland (https://github.com/gumchum)
+* Add Bulgarian holidays (https://github.com/thekazak)
+* Add new mountain holiday for Japan (https://github.com/ttwo32)
+* Add ability to calculate Easter in either Gregorian (existing) or Julian (new) dates
+
+## 3.0.0
+
+* Major refactor! Lots of code moved around and some methods were removed from the public api (they were never intended to be public).
+* Only supports ruby 2.0.0 and up. Travis config has been updated to reflect this.
+* Moves 'date' monkeypatching out of main lib and makes it a core extension. See README for usage.
+* Fixes remote execution bug in issue-86 (thanks to https://github.com/Intrepidd for reporting)
+* No region definition changes.
+
+I decided to make this a major version bump due to how much I changed. I truly hope no one will notice.
+See the README for the usage. It has, except for the date core extension, not changed.
+
+## 2.2.0
+
+* Correct 'informal' type for Dodenherdenking holiday in NL definitions (https://github.com/MathijsK93)
+

+# Ruby Holidays Gem [![Build Status](https://travis-ci.org/holidays/holidays.svg?branch=master)](https://travis-ci.org/holidays/holidays)
+
+Functionality to deal with holidays in Ruby.
+
+Extends Ruby's built-in Date and Time classes and supports custom holiday definition lists.
+
+## Installation
+
+```
+gem install holidays
+```
+
+## Tested versions
+
+This gem is tested with the following ruby versions:
+
+  * 2.4.5
+  * 2.5.3
+  * 2.6.1
+  * JRuby 9.2.5.0
+
+## Semver
+
+This gem follows [semantic versioning](http://semver.org/). The guarantee specifically covers:
+
+ * methods in the top-most `Holidays` namespace e.g. `Holidays.<method>`
+ * the [core extensions](#extending-rubys-date-and-time-classes)
+
+Please note that we consider definition changes to be 'minor' bumps, meaning they are backwards compatible with your code but might give different holiday results!
+
+## Time zones
+
+Time zones are ignored.  This library assumes that all dates are within the same time zone.
+
+## Usage
+
+This gem offers multiple ways to check for holidays for a variety of scenarios.
+
+#### Checking a specific date
+
+Get all holidays on April 25, 2008 in Australia:
+
+```
+Holidays.on(Date.civil(2008, 4, 25), :au)
+=> [{:name => 'ANZAC Day',...}]
+```
+
+You can check multiple regions in a single call:
+
+```
+Holidays.on(Date.civil(2008, 1, 1), :us, :fr)
+=> [{:name=>"New Year's Day", :regions=>[:us],...},
+    {:name=>"Jour de l'an", :regions=>[:fr],...}]
+```
+
+You can leave off 'regions' to get holidays for any region in our [definitions](https://github.com/holidays/definitions):
+
+```
+ Holidays.on(Date.civil(2007, 4, 25))
+=> [{:name=>"ANZAC Day", :regions=>[:au],...},
+    {:name=>"Festa della Liberazione", :regions=>[:it],...},
+    {:name=>"Dia da Liberdade", :regions=>[:pt],...}
+    ...
+   ]
+```
+
+#### Checking a date range
+
+Get all holidays during the month of July 2008 in Canada and the US:
+
+```
+from = Date.civil(2008,7,1)
+to = Date.civil(2008,7,31)
+
+Holidays.between(from, to, :ca, :us)
+=> [{:name => 'Canada Day',...}
+    {:name => 'Independence Day',...}]
+```
+
+#### Check for 'informal' holidays
+
+You can pass the 'informal' flag to include holidays specified as informal in your results. See [here](https://github.com/holidays/definitions/blob/master/doc/SYNTAX.md#formalinformal) for information on what constitutes 'informal' vs 'formal'.
+
+By default this flag is turned off, meaning no informal holidays will be returned.
+
+Get Valentine's Day in the US:
+
+```
+Holidays.on(Date.new(2018, 2, 14), :us, :informal)
+=> [{:name=>"Valentine's Day",...}]
+```
+
+Leaving off 'informal' will mean that Valentine's Day is not returned:
+
+```
+Holidays.on(Date.new(2018, 2, 14), :us)
+=> []
+```
+
+Get informal holidays during the month of February 2008 for any region:
+
+```
+from = Date.civil(2008,2,1)
+to = Date.civil(2008,2,15)
+
+Holidays.between(from, to, :informal)
+=> [{:name => 'Valentine\'s Day',...}]
+```
+
+#### Check for 'observed' holidays
+
+You can pass the 'observed' flag to include holidays that are observed on different days than they actually occur. See [here](https://github.com/holidays/definitions/blob/master/doc/SYNTAX.md#observed) for further explanation of 'observed'.
+
+By default this flag is turned off, meaning no observed logic will be applied.
+
+Get holidays that are observed on Monday July 2, 2007 in British Columbia, Canada:
+
+```
+Holidays.on(Date.civil(2007, 7, 2), :ca_bc, :observed)
+=> [{:name => 'Canada Day',...}]
+```
+
+Leaving off the 'observed' flag will mean that 'Canada Day' is not returned since it actually falls on Sunday July 1:
+
+```
+Holidays.on(Date.civil(2007, 7, 2), :ca_bc)
+=> []
+Holidays.on(Date.civil(2007, 7, 1), :ca_bc)
+=> [{:name=>"Canada Day", :regions=>[:ca],...}]
+```
+
+Get all observed US Federal holidays between 2018 and 2019:
+
+```
+from = Date.civil(2018,1,1)
+to = Date.civil(2019,12,31)
+
+Holidays.between(from, to, :federalreserve, :observed)
+=> [{:name => "New Year's Day"....}
+    {:name => "Birthday of Martin Luther King, Jr"....}]
+```
+
+#### Check whether any holidays occur during work week
+
+Check if there are any holidays taking place during a specified work week. 'Work week' is defined as the period of Monday through Friday of the week specified by the date.
+
+Check whether a holiday falls during first week of the year for any region:
+
+```
+Holidays.any_holidays_during_work_week?(Date.civil(2016, 1, 1))
+=> true
+```
+
+You can also pass in `informal` or `observed`:
+
+```
+# Returns true since Valentine's Day falls on a Wednesday
+holidays.any_holidays_during_work_week?(date.civil(2018, 2, 14), :us, :informal)
+=> true
+# Returns false if you don't specify informal
+irb(main):006:0> Holidays.any_holidays_during_work_week?(Date.civil(2018, 2, 14), :us)
+=> false
+# Returns true since Veteran's Day is observed on Monday November 12, 2018
+holidays.any_holidays_during_work_week?(date.civil(2018, 11, 12), :us, :observed)
+=> true
+# Returns false if you don't specify observed since the actual holiday is on Sunday November 11th 2018
+irb(main):005:0> Holidays.any_holidays_during_work_week?(Date.civil(2018, 11, 12), :us)
+=> false
+```
+
+#### Find the next holiday(s) that will occur from a specific date
+
+Get the next holidays occurring from February 23, 2016 for the US:
+
+```
+Holidays.next_holidays(3, [:us, :informal], Date.civil(2016, 2, 23))
+=> [{:name => "St. Patrick's Day",...}, {:name => "Good Friday",...}, {:name => "Easter Sunday",...}]
+```
+
+You can specify the number of holidays to return. This method will default to `Date.today` if no date is provided.
+
+#### Find all holidays occuring starting from a specific date to the end of the year
+
+Get all holidays starting from February 23, 2016 to end of year in the US:
+
+```
+Holidays.year_holidays([:ca_on], Date.civil(2016, 2, 23))
+=> [{:name=>"Good Friday",...},
+    {name=>"Easter Sunday",...},
+    {:name=>"Victoria Day",...},
+    {:name=>"Canada Day",...},
+    {:name=>"Civic Holiday",...},
+    {:name=>"Labour Day",...},
+    {:name=>"Thanksgiving",...},
+    {:name=>"Remembrance Day",...},
+    {:name=>"Christmas Day",...},
+    {:name=>"Boxing Day",...}]
+```
+
+This method will default to `Date.today` if no date is provided.
+
+#### Return all available regions
+
+Return all available regions:
+
+```
+Holidays.available_regions
+=> [:ar, :at, ..., :sg] # this will be a big array
+```
+
+## Loading Custom Definitions on the fly
+
+In addition to the [provided definitions](https://github.com/holidays/definitions) you can load custom definitions file on the fly and use them immediately.
+
+To load custom 'Company Founding' holiday on June 1st:
+
+```
+Holidays.load_custom('/home/user/holiday_definitions/custom_holidays.yaml')
+Holidays.on(Date.civil(2013, 6, 1), :my_custom_region)
+  => [{:name => 'Company Founding',...}]
+```
+
+Custom definition files must match the [syntax of the existing definition files](https://github.com/holidays/definitions/blob/master/doc/SYNTAX.md).
+
+Multiple files can be loaded at the same time:
+
+```
+Holidays.load_custom('/home/user/holidays/custom_holidays1.yaml', '/home/user/holidays/custom_holidays2.yaml')
+```
+
+## Extending Ruby's Date and Time classes
+
+### Date
+
+To extend the 'Date' class:
+
+```
+require 'holidays/core_extensions/date'
+class Date
+  include Holidays::CoreExtensions::Date
+end
+```
+
+Now you can check which holidays occur in Iceland on January 1, 2008:
+
+```
+d = Date.civil(2008,7,1)
+
+d.holidays(:is)
+=> [{:name => 'Nýársdagur'}...]
+```
+
+Or lookup Canada Day in different regions:
+
+```
+d = Date.civil(2008,7,1)
+
+d.holiday?(:ca) # Canada
+=> true
+
+d.holiday?(:ca_bc) # British Columbia, Canada
+=> true
+
+d.holiday?(:fr) # France
+=> false
+```
+
+Or return the new date based on the options:
+
+```
+d = Date.civil(2008,7,1)
+d.change(:year => 2016, :month => 1, :day => 1)
+=> #<Date: 2016-01-01 ((2457389j,0s,0n),+0s,2299161j)>
+```
+
+Or you can calculate the day of the month:
+
+```
+Date.calculate_mday(2015, 4, :first, 2)
+=> 7
+```
+
+### Time
+
+```
+require 'holidays/core_extensions/time'
+class Time
+  include Holidays::CoreExtensions::Time
+end
+```
+
+Find end of month for given date:
+
+```
+d = Date.civil(2016,8,1)
+d.end_of_month
+=> #<Date: 2016-08-31 ((2457632j,0s,0n),+0s,2299161j)>
+```
+
+## Caching Holiday Lookups
+
+If you are checking holidays regularly you can cache your results for improved performance. Run this before looking up a holiday (e.g. in an initializer):
+
+```
+YEAR = 365 * 24 * 60 * 60
+Holidays.cache_between(Time.now, Time.now + 2 * YEAR, :ca, :us, :observed)
+```
+
+Holidays for the regions specified within the dates specified will be pre-calculated and stored in-memory. Future lookups will be much faster.

+
+
+## 5.0.1
+
+No behavior change.
+
+Commenting out a failing `it` test due to limitations of the current definition format. Unfortunately a holiday was added to the `it` region that falls on the same day as another existing region and we do not alwayd handle that in a uniform, consistent way. Currently there is no way to test that the _second_ region that is returned on a day is valid. Because of this I'm commenting out the test and moving forward. We'll need to add this functionality later.
+
+I only caught this when releasing the ruby gem. This goes back once again to [this issue](https://github.com/holidays/definitions/issues/42) with how we can test against an actual implementation from this repository.
+
+## 5.0.0
+
+Major semver bump due to changes related to the `year_ranges` option. The following keys have been renamed:
+
+* `before` is now `until`
+* `after` is now `from`
+
+The behavior of these two options has not changed. To read more about the reasons behind this change please see the [associated ADR](doc/architecture/adr-002.md).
+
+Definitions changes:
+
+* Fix typos and syntax on `th` defs
+* Update Christmas-related holidays in `us` and `ca` (thanks to https://github.com/jonjonw)
+* Add `it_rm` as `it` subregion (thanks to https://github.com/stephane)
+* Update `it` subregions for accuracy (thanks to https://github.com/nolith and https://github.com/NatyDev)
+* Add `ro` region (thanks to https://github.com/stephane)
+* Update `il` and `ca` holidays for accuracy (thanks to https://github.com/ghiculescu)
+* Add `lv` region (thanks to https://github.com/aleksandrs-ledovskis)
+* Update `es` holidays (thanks to https://github.com/thefabbulus)
+* Update `gb` region to fix May Day (thanks to https://github.com/LauraBondini)
+* Update `hu` region for Easter accuracy (thanks to https://github.com/HuBandiT)
+
+## 4.1.0
+
+* Add new Emperor's Coronation Day holiday to `jp` (thanks to https://github.com/ttwo32)
+* Add Thai Holidays (whoooo) (thanks to https://github.com/fabersky)
+* Add Berlin's New International Women's Day to `de_be` (thanks to https://github.com/iGEL)
+* Add Civic Holiday (Terry Fox Day) to `ca_mb` (thanks to https://github.com/akaspick)
+* Fix Federal Reserve holidays for Independence Day (thanks to https://github.com/chadrschroeder)
+
+## 4.0.0
+
+Major semver bump due to changes in how non-standard regions will be handled going forward. Please see [issue-110](https://github.com/holidays/definitions/issues/110) for more details on this edge case and please also see the updates to our [SYNTAX guide](doc/SYNTAX.md#non-standard-regions) for the specified behavior going forward.
+
+The following non-standard regions have been changed:
+
+* `ecb_target` region changed to `ecbtarget`
+* `federal_reserve` region changed to `federalreserve`
+* `federal_reserve_banks` region changed to `federalreservebanks`
+* `north_america_informal` region changed to `northamericainformal`
+* `united_nations` region changed to `unitednations`
+* `north_america` region changed to `northamerica`
+* `south_america` region changed to `southamerica`
+
+This change also includes updates to various other regions:
+
+* Rename national sports day of `:jp` region from "体育の日" to "スポーツの日" (thanks to https://github.com/kunitoo)
+* Fix 2020 `:jp` region holidays related tokyo olympics (thanks to https://github.com/kunitoo)
+* Update Family Day date in `:ca_bc` region (thanks to https://github.com/roman-ih)
+* Add Ukrainian holidays (`:ua` region code) (thanks to https://github.com/roman-ih)
+* Add `federalreservebanks` region for observed bank holidays (thanks to Matt Hickman)
+
+## 3.1.0
+
+* Update `ch` to apply 'Neujahrstag' to overall region (thanks to https://github.com/phylor)
+* Cosmetic spacing update for `us` definition, no behavior change
+
+## 3.0.0
+
+Major semver bump as the format for custom methods has been changed to complete [issue-24](https://github.com/holidays/definitions/issues/24). Downstream consumers will need to update to be able to parse them. However there are **no behavior changes** with this update.
+
+In summary: we have switched to language-specific custom methods. Instead of a plain `source` field you will need a specific language implementation, e.g. `ruby`, `golang`, etc.
+
+Currently we only have `ruby` but we can now expand these definitions for use in other languages. Please see the [custom methods ADR](doc/architecture/adr-001.md) for more in-depth information on why this change was made.
+
+You can also view the updated ['Methods' section in the SYNTAX doc](doc/SYNTAX.md#methods) for more info and examples.

+
+* `ca_ab` - change 'Heritage Day' to informal
+* `kr` - Update '추석 연휴' and `설날 연휴` for accuracy

+
+## 2.0.0
+
+* Update `tr`, `fedex` for accuracy
+* Completely change the test format to no longer use ruby source code! Hooray! This should cause no behavior differences,
+  any differences or changes in behavior should be considered a regression.
+
+## 1.7.1
+
+A small bugfix that resolves the naming issues of two regions in the 'index.yaml' file. No other outward changes.
+

+
+## 1.6.1
+
+* Update `ca` test for correctness. See below for more information.
+
+Unfortunately due to our current setup it is possible for definitions/tests in this repository to appear 'valid' but only
+fail when we run them in the actual ruby holidays repo. This is a known issue (#42) and needs to be addressed.
+
+In the meantime, this is a bugfix release to ensure we can release v5.6.0 of the ruby repo.
+

+* Add KR definitions
+* Fix small bug in JP definitions
+
+## 2016 1.0.0
+
+Initial creation of this repository
+
+This contains all of the definitions currently in the holidays repository but split out into its own repository. It will
+be added as a submodule of the ruby repository, which will be responsible for generating its final classes.
+
+The idea is that we will have repositories for multiple languages and each language is responsible for using the definitions
+as it sees fit.

+# Holidays Definitions [![Build Status](https://travis-ci.org/holidays/definitions.svg?branch=master)](https://travis-ci.org/holidays/definitions)
+
+This repository contains the 'raw' definitions for the various holidays projects. It should be added a submodule to
+any project that wants to use them.
+
+Currently it is only used by the [existing Holidays gem](https://github.com/holidays/holidays), which takes these
+definitions and generates ruby classes for use in that gem. In the future it will be used by other languages in
+a similar manner.
+
+**Please note** that this is _not_ a gem. The validation process is written in ruby simply for convenience. The real
+stars of this show are the YAML files.

+# Word of warning:
+# ================
+# As the holidays are defined on a state level and sometimes even on a district / village level,
+# this holiday definition is an approximation of the reality. It should be accurate for most of the cases but
+# no guarantee is given that it is correct for all the special cases :-).
+# Considers both official holidays and holidays that are handled as if they were official holidays.
+#
+# Holiday names are in German in case they are celebrated in the German speaking area and in French / Italian otherwise.
+#
+# Known Issues:
+# * ch_ur: 26th of December is not celebrated in case the 25th is a Monday or a Friday.
+# * ch_fr: Fronleichnam, Maria Himmelfahrt, Allerheiligen, Maria Empfaengnis is celebrated in all villages except
+#         some villages of the district of See.
+# * ch_so:  - There are a lot of village holidays not included here.
+#           - 1st of May is holiday only starting at noon; not included here.
+#           - 19th of March is celebrated only in a couple of villages
+# * ch_ar: 26th of December is not celebrated in case the 25th is a Monday or a Friday.
+# * ch_ai: - 22nd of September is celebrated only in part of the state.
+#          - 26th of December is not celebrated in case the 25th is a Monday or a Friday.
+# * ch_ne: 26th of December and 2nd of January are only celebrated in case 25th of December and 1st of January are Sundays

+# German holiday definitions for the Ruby Holiday gem.
+#
+# Updated: 2019-02-10
+#
+# Changes 2016-11-27:
+# - Change de_sn_aux, de_th_aux to de_sn_sorbian (because it only is celebrated in Sorbian regions in Sachsen) and de_th_eichsfeld, to reflect region of Eichsfeld
+# - Change de_sn_aux to de_by_augsburg to reflect only City of Augsburg
+#
+# Changes 2017-06-08:
+# - Add Berlin, Bremen, Hamburg, Niedersachsen, Schleswig-Holstein
+# - Change de_th_eichsfeld to de_th_cath because it affects the catholic communities Eichsfeld, Unstrut-Hainich-Kreis and Wartburgkreis
+# - Merge Fronleichnam entry
+# - Add de_by_cath for catholic communities in Bavaria; Maria Himmelfahrt is not a Bavaria-wide holiday
+# - Mariä Himmelfahrt is celebrated in the community of Augsburg (de_by_augsburg)
+# - Enhance tests
+#
+# Changes 2017-09-25:
+# - Correct definition for Reformation Day
+#
+# Changes 2018-09-10:
+#  - Reformation Day has been added as a new holiday in Bremen, Hamburg, Lower Saxony and Schleswig-Holstein, starting in 2018.
+#
+# Change 2019-02-10:
+#  - Changing usage of 'year_ranges.after' to 'year_ranges.from', see https://github.com/holidays/definitions/issues/117

+# How to contribute
+
+In this repository we have all of the definitions that are used in holiday calcuations. We rely on users around the world to help keep our definitions accurate and up to date.
+
+## Code of Conduct
+
+Please read our [Code of Conduct](https://github.com/holidays/holidays/blob/master/CODE_OF_CONDUCT.md) before contributing. Everyone interacting with this project (or associated projects) is expected to abide by its terms.
+
+## Definition Updates
+
+Our definitions are written in YAML. You can find a complete guide to our format in the [syntax docs](SYNTAX.md). We take the YAML definitions and generate final definition files in the various projects that are loaded at runtime for fast calculations.
+
+Here are the steps to take once you have a good idea on what you want to change:
+
+* Fork this repository
+* Edit desired definition YAML file(s). If you are adding a new region be sure to update `index.yaml` as well
+* Run `make validate` to ensure that all updates match our definition format
+* Open a PR with your changes
+
+Including documentation with your updates is very much appreciated. A simple Wikipedia entry or government link in the comments alongside your changes would be perfect.
+
+Lastly, note that there are many 'meta' regions. For example, there are regions for Europe, Scandinavia, and North America. If your new region(s) falls into these areas consider adding them. You can find these 'meta' regions in `definitions/index.yaml`.
+
+Don't worry about versioning, we'll handle it on our end.
+
+*Tests are required for new definitions*.
+
+## Definition Validation
+
+We maintain a `make validate` command to ensure that all YAML definitions match our internal specifications. This is to make working with this repository as independent as possible from the other repositories (like the existing ruby repository). If `make validate` passes then we ensure that anything consuming these files will receive 'correct' formats.
+
+If you run into any weird `make validate` errors please open an issue or PR and highlight to what you are seeing. The validation code is brand-new and might have issues. Maintainers will respond quickly to any open problems.
+
+If you would like to add to, update, or otherwise fix any of our specs then please fork and submit a PR like you would any other change. Please note that we require 100% test coverage. Your builds will not pass if you fall below 100%.

+# Maintainers guide
+
+This document outlines the process of releasing an update of the definitions in this repository. Please note
+that this document does NOT try to explain how to create packages for various languages. It is *just*
+for creating version snapshots of definition files.
+
+To be as clear as possible: this repository is *just* for definition updates. We 'release' updates as tags in Github
+but do not push any code updates. Downstream projects (like ruby) will consume this and make their own appropriate releases.
+The 'releases' in this project are mainly for organizational purposes.
+
+### Who this document is for
+
+This document is for maintainers that have merge access to this repository. Generally these people will also have access to any
+language-specific libraries and so this will be a part of the entire release process. Usually other libraries (like the ruby library)
+will reference this document as part of its own release process.
+
+Please note that a core contributor must provide the relevant Github access so that you can perform merges. If you have any issues
+please contact the [core members](https://github.com/orgs/holidays/teams/core/members) for assistance.
+
+### Setup
+
+This guide assumes that you have forked the repository in Github. If you require assistance in this please contact the core members listed above.
+
+### Merging new definition changes
+
+When new PRs are submitted you can navigate the following steps:
+
+* Make sure that the PR Travis CI builds are green. If they are green then you can simply continue. If there are errors you
+will need to investigate further (contact a core member for assistance).
+* If the builds are green and the changes look reasonable to you then go ahead and merge!
+* Once the merges are done, make a new branch on your fork that includes an updated [CHANGELOG](https://github.com/holidays/definitions/blob/master/CHANGELOG.md)
+that has the new version and associated changes. This is pretty open-ended! Include the information that you feel is
+important. Use past CHANGELOG updates as a guide.
+* Open a PR against the CHANGELOG branch and merge it (this may require another maintainer for safety)
+* Once the updated CHANGELOG is merged, go to [releases](https://github.com/holidays/definitions/releases) and create a new release. It should point at the latest commit that contains the changes that you want included in this release. If you just merged then you can just point at master.  All release versions follow this format: `vMAJOR.MINOR.PATCH`. This should follow normal [semver rules](https://semver.org/).
+
+You don't need to list out the specific changes that were made on the release description. You can just give a general overview and then link to the updated CHANGELOG that you did in a previous step. Example: [v2.2.0](https://github.com/holidays/definitions/releases/tag/v2.2.0)
+
+Once the release is created in Github you are done! The definitions have been 'released' and downstream projects (right now just ruby) can reference them without issues. See the maintainers guides in downstream projects for information on how to release updates for each language.

+# Holiday Definition Syntax
+
+The definition syntax is a custom format developed over the life of this project. All holidays are defined in these YAML files. These definition files have three main top-level properties:
+
+* `months` - this is the meat! All definitions for months 1-12 are defined here
+* `methods` - this contains any custom logic that your definitions require
+* `tests` - this contains the tests for your definitions
+
+The `months` property is required. The two other properties are not strictly required but are almost always used.
+
+In fact, if you leave out `tests` your PR will probably not be accepted unless there is a very, very good reason for leaving it out.
+
+## Key Words
+
+There are some terms that you should be familiar with before we dive into each section:
+
+#### `region`
+
+A region is a symbol that denotes the geographic or cultural region for that holiday. In general these symbols will be the [ISO 3166](https://en.wikipedia.org/wiki/ISO_3166) code for a country or region.
+
+##### Sub-region
+
+We also have a concept of a `sub-region`. These regions exist inside of a 'parent' region and inherit the parent's holidays. We use an underscore to specify a subregion.
+
+Examples:
+
+* `:us_dc` for Washington, D.C in `:us`
+* `:ca_bc` for British Columbia in `:ca`
+
+Some sub-regions do not have a matching ISO 3116 entry. In these cases we attempt to choose symbols that are reasonably clear.
+
+##### Non-standard regions
+
+Before version v1.1.0 of the original ruby gem the compliance with ISO 3166 was not as strict. There might be cases where an existing region symbol does not match the ISO standard.
+
+Non-standard regions (e.g. `ecbtarget`, `federalreserve`, etc) must be all one word, just like a normal region. They must not use underscores or hyphens.
+
+#### `formal`/`informal`
+
+We consider `formal` dates as government-defined holidays. These could be the kinds of holidays where everyone stays home from work or perhaps are bank holidays but it is *not required* for a holiday to have these features to be considered formal.
+
+`Informal` holidays are holidays that everyone knows about but aren't enshrined in law. For example, Valentine's Day in the US is considered an informal holiday.
+
+We recognize that these definitions can be highly subjective. If you disagree with the current status of a holiday please open an issue so we can discuss it.
+
+#### `observed`
+
+There are certain holidays that can be legally observed on different days than they occur. For example, if a holiday falls on a Saturday but it is legally observed on the following Monday then you can define it as `observed` on the Monday. Please see the section below for more details and examples.
+
+## Months
+
+Holidays are grouped by month from 1 through 12.  Each entry within a month can have several properties depending on the behavior of the holiday. Each section below lays out the various different ways you can define your holiday.
+
+The two required properties are:
+
+* `name` - The name of the holiday
+* `regions` - One or more region codes (targeted to match [ISO 3166](https://en.wikipedia.org/wiki/ISO_3166))
+
+### Dates defined by a fixed date (e.g. January 1st)
+
+* `mday` - A non-negative integer representing day of the month (1 through 31).
+
+For example, the following holiday is on the first of January and available in the `:ca`, `:us` and `:au` regions:
+
+```yaml
+1:
+- name: New Year's Day
+  regions: [ca, us, au]
+  mday: 1
+```
+
+### Dates defined by a week number (e.g. first Monday of a month)
+
+* `wday` - A non-negative integer representing day of the week (0 = Sunday through 6 = Saturday).
+* `week` - A non-negative integer representing week number (1 = first week, 3 = third week, -1 = last week),
+
+For example, the following holiday is on the first Monday of September and available in the `:ca` region:
+
+```yaml
+9:
+- name: Labour Day
+  regions: [ca]
+  week: 1
+  wday: 1
+```
+
+### 'Formal' vs 'Informal' types
+
+As mentioned above you can specify two different types. By default a holiday is considered 'formal'. By adding a `type: informal` to a definition you will mark it as 'informal' and it will only show up if the user specifically asks for it.
+
+Example:
+
+```yaml
+9:
+- name: Some Holiday
+  regions: [fr]
+  mday: 1
+  type: informal
+```
+
+If a user submits:
+
+```ruby
+Holidays.on(Date.civil(2016, 9, 1), :fr)
+```
+
+Then they will not see the holiday. However, if they submit:
+
+```ruby
+Holidays.on(Date.civil(2016, 9, 1), :fr, :informal)
+```
+
+Then the holiday will be returned. This is especially useful for holidays like "Valentine's Day" in the USA, where it is commonly recognized as a holiday in society but not as a day that is celebrated by taking the day off.
+
+### Year ranges
+
+Certain holidays in various countries are only in effect during specific year ranges. A few examples of this are:
+
+* A new holiday that starts in 2017 and continues into the future
+* An existing holiday that has been cancelled so that the final year in effect is 2019
+* A historical holiday that was only in effect from 2002 through 2006
+
+To address these kinds of scenarios we have the ability to specify 'year ranges' for individual holiday definitions. There are a total of four selectors that can be specified. All must be specified in terms of 'years'. Only one selector can be used at a time.
+
+#### `until`
+
+The 'until' selector will only return a match if the supplied date takes place in the same year as the holiday or earlier.
+
+A single integer representing a year *must* be supplied. An array of values will result in an error.
+
+Example:
+
+```yaml
+7:
+  name: 振替休日
+  regions: [jp]
+  mday: 1
+  year_ranges:
+    until: 2002
+```
+
+This will return successfully since the date is before 2002:
+
+```ruby
+Holidays.on(Date.civil(2000, 7, 1), :jp)
+```
+
+This will also return successfully since the date takes place on 2002 exactly:
+
+```ruby
+Holidays.on(Date.civil(2002, 7, 1), :jp)
+```
+
+This will not since the date is after 2002:
+
+```ruby
+Holidays.on(Date.civil(2016, 7, 1), :jp)
+```
+
+#### `from`
+
+The 'from' selector will only return a match if the supplied date takes place in the same year as the holiday or later.
+
+A single integer representing a year *must* be supplied. An array of values will result in an error.
+
+Example:
+
+```yaml
+7:
+  name: 振替休日
+  regions: [jp]
+  mday: 1
+  year_ranges:
+    from: 2002
+```
+
+This will return successfully since the date is after 2002:
+
+```ruby
+Holidays.on(Date.civil(2016, 7, 1), :jp)
+```
+
+This will also return successfully since the date takes place on 2002 exactly:
+
+```ruby
+Holidays.on(Date.civil(2002, 7, 1), :jp)
+```
+
+This will not since the date is before 2002:
+
+```ruby
+Holidays.on(Date.civil(2000, 7, 1), :jp)
+```
+
+#### `limited`
+
+The 'limited' selector will only find a match if the supplied date takes place during
+one of the specified years. Multiple years can be specified.
+
+An array of integers representing years *must* be supplied. Providing anything other than an array of integers will result in an error.
+
+Please note that this is *not* a range! This is an array of specific years during which the holiday is active. If you need a year range please see the `between` selector below.
+
+Example:
+
+```yaml
+7:
+  name: 振替休日
+  regions: [jp]
+  mday: 1
+  year_ranges:
+    limited: [2002,2004]
+```
+
+Both of these examples will return successfully since the dates takes place in 2002 and 2004 exactly:
+
+```ruby
+Holidays.on(Date.civil(2002, 7, 1), :jp)
+Holidays.on(Date.civil(2004, 7, 1), :jp)
+```
+
+Neither of these will return since the dates takes place in outside of 2002 and 2004:
+
+```ruby
+Holidays.on(Date.civil(2000, 7, 1), :jp)
+Holidays.on(Date.civil(2003, 7, 1), :jp)
+```
+
+#### `between`
+
+The 'between' selector will only find a match if the supplied date takes place during the specified _inclusive_ range of years.
+
+To use this selector you *must* provide both a `start` and `end` key. Both values must be integers representing years.
+
+Example:
+
+```yaml
+7:
+  name: 振替休日
+  regions: [jp]
+  mday: 1
+  year_ranges:
+    between:
+      start: 1996
+      end: 2002
+```
+
+These examples will return successfully since they take place within the specified range:
+
+```ruby
+Holidays.on(Date.civil(1996, 7, 1), :jp)
+Holidays.on(Date.civil(2000, 7, 1), :jp)
+Holidays.on(Date.civil(2002, 7, 1), :jp)
+```
+
+These will not since both are outside of the specified start/end range:
+
+```ruby
+Holidays.on(Date.civil(2003, 7, 1), :jp)
+Holidays.on(Date.civil(1995, 7, 1), :jp)
+```
+
+## Methods
+
+Sometimes you need to perform a complex calculation to determine a holiday. To facilitate this we allow for users to specify custom methods to calculate a date. These should be placed under the `methods` property. Methods named in this way can then be referenced by entries in the `months` property.
+
+#### Important note
+
+One thing to note is that these methods are _language specific_ at this time, meaning we would have one for ruby, one for golang, etc. Coming up with a standardized way to represent the logic in the custom-written methods proved to be very difficult. This is a punt until we can come up with a better solution.
+
+Please feel free to only add the custom method source in the language that you choose. It will be up to downstream maintainers to ensure that their language has an implementation. So if you only want to add it in ruby please just do that!
+
+### Method Example
+
+Canada celebrates Victoria Day, which falls on the Monday on or before May 24. Under the `methods` property we would create a custom method for ruby that returns a Date object:
+
+```yaml
+methods:
+  ca_victoria_day:
+    arguments: year
+    ruby: |
+      date = Date.civil(year, 5, 24)
+      if date.wday > 1
+        date -= (date.wday - 1)
+      elsif date.wday == 0
+        date -= 6
+      end
+
+      date
+```
+
+This could then be used in a `months` entry:
+
+```yaml
+5:
+- name: Victoria Day
+  regions: [ca]
+  function: ca_victoria_day(year)
+```
+
+### Available arguments
+
+You may only specify the following values for arguments into a custom method: `date`, `year`, `month`, `day`, `region`
+
+Correct example:
+
+```yaml
+1:
+- name: Custom Method
+  regions: [us]
+  function: custom_method(year, month, day)
+```
+
+The following will return an error since `week` is not a recognized argument:
+
+```yaml
+1:
+- name: Custom Method
+  regions: [us]
+  function: custom_method(week)
+```
+
+#### Whaa? Why do you restrict what I can pass in?
+
+This was done as an attempt to make it easier for the downstream projects to parse and use the custom methods. They have to be able to pass in the required data so we limit it to make that process easier.
+
+We can add to this list if your custom logic needs something else! Open an issue with your use case and we can discuss it.
+
+### Methods without a fixed month
+
+If a holiday does not have a fixed month (e.g. Easter) it should go in the '0' month:
+
+```yaml
+0:
+- name: Easter Monday
+  regions: [ca]
+  function: easter(year)
+```
+
+### Pre-existing methods
+
+There are pre-existing methods for highly-used calculations. You can reference these methods in your definitions as you would a custom method that you have written:
+
+* `easter(year)` - calculates Easter via Gregorian calendar for a given year
+* `orthodox_easter(year)` - calculates Easter via Julian calendar for a given year
+* `to_monday_if_sunday(date)` - returns date of the following Monday if the 'date' argument falls on a Sunday
+* `to_monday_if_weekend(date)` - returns date of the following Monday if the 'date' argument falls on a weekend (Saturday or Sunday)
+* `to_weekday_if_boxing_weekend(date)` - returns nearest following weekday if the 'date' argument falls on Boxing Day
+* `to_weekday_if_boxing_weekend_from_year(year)` - calculates nearest weekday following Boxing weekend for given year
+* `to_weekday_if_weekend(date)` - returns nearest weekday (Monday or Friday) if 'date' argument falls on a weekend (Saturday or Sunday)
+
+*Protip*: you can use the `easter` methods to calculate all of the dates that are based around Easter. It's especially useful to use since the Easter calculation is complex. For example, 'Good Friday' in the US is 2 days before Easter. Therefore you could do the following:
+
+```
+0:
+- name: Good Friday
+  regions: [us]
+  function: easter(year)
+  function_modifier: -2
+  type: informal
+```
+
+Use the `function_modifier` property, which can be positive or negative, to modify the result of the function.
+
+### Calculating observed dates
+
+Users can specify that this gem only return holidays on their 'observed' day. This can be especially useful if they are using this gem for business-related logic. If you wish for your definitions to allow for this then you can add the `observed` property to your entry. This requires a method to help calculate the observed day.
+
+Several built-in methods are available for holidays that are observed on varying dates.
+
+For example, for a holiday that is observed on Monday if it falls on a weekend you could write:
+
+```
+7:
+- name: Canada Day
+  regions: [ca]
+  mday: 1
+  observed: to_monday_if_weekend(date)
+```
+
+If a user does not specify `observed` in the options then 7/1 will be the date found for 'Canada Day', regardless of whether it falls on a Saturday or Sunday. If a user specifies 'observed' then it will show as the following Monday if the date falls on a Saturday or Sunday.
+
+## Tests
+
+All definition files should have tests included. At this time we do not enforce any rules on coverage or numbers of tests. However, in general, PRs will not be accepted if they are devoid of tests that cover the changes in question.
+
+The format is a straightforward 'given/expect'. Here is a simple example:
+
+```yaml
+- given:
+    date: '2018-1-1'
+    regions: ["ex"]
+  expect:
+    name: "Example Holiday"
+```
+
+Here are format details:
+
+* given (required)
+  * date (required) - all dates must be in 'YYYY-MM-DD' format. Either a single day or an array of dates can be used.
+  * regions (required) - an array of strings (NOT symbols). Multiple regions can be passed. Even a single region must be in an array.
+  * options (optional) - an array of options to use for this test. Can be either 'informal' or 'observed'. Must be an array of strings, e.g. `['informal', 'observed']`
+* expect (required)
+  * name (optional) - the name of the holiday you are expecting. Must be a string.
+  * holiday (optional) - a boolean indicating whether the given values result in a holiday. Defaults to 'true' if not present. Must be true or false.
+
+One or the other of the `expect` keys is required. If you do not specify a `name` then you should set `holiday: false`.
+
+#### Test Examples
+
+First example shows multiple dates, multiple regions, additional options, and an expectation that the result will be the named holiday:
+
+```yaml
+- given:
+    date: ['2018-1-1', '2019-3-5']
+    regions: ["ex", "ex2", "ex3"]
+    options: ["informal"]
+  expect:
+    name: "Example Holiday"
+```
+
+Second example shows multiple dates, a single region, multiple options, and an expectation that the given values will *not* result in a found holiday. No name is required because...no holiday is expected to be found.
+
+```yaml
+- given:
+    date: ['2022-12-1', '2019-4-1', '2046-8-8]
+    regions: ["ex"]
+    options: ["informal", "observed"]
+  expect:
+    holiday: false
+```
+
+These tests will be picked up by the `generate` process in the client repositories and written into actual tests in the given language that are run when a user executes the test suite.
+
+Please please please include tests. Your PR won't be accepted if tests are not included with your changes.

+# ADR 1: Custom Methods Format Change
+
+## Context
+
+We would like these definitions to be usable by any language. The original `holidays` project was written purely in `ruby` but the definitions were generally plain `YAML`.
+
+The issue is that `ruby` has been sprinkled into the otherwise plain `YAML` when it made sense with no plan for use outside of `ruby`. This makes sense when you are never planning on using the `YAML` files in other languages.
+
+Over time we have [been working](https://github.com/holidays/definitions/issues/7) to make the syntax more generic so that other language implementations could consume them. The last hurdle was custom methods.
+
+An example of the original format:
+
+```yaml
+methods:
+  ca_victoria_day:
+    arguments: year
+    source: |
+      date = Date.civil(year, 5, 24)
+      if date.wday > 1
+        date -= (date.wday - 1)
+      elsif date.wday == 0
+        date -= 6
+      end
+
+      date
+```
+
+As you can see the actual function is just plain `ruby`.
+
+After lots of trial and error I have decided that I cannot see a generic format for this logic that would satisfy all use cases for existing custom methods in our definitions. While some custom methods are relatively simple `if/else` statements there are many that are much more complicated.
+
+An example of a 'complicated' custom method from the `ch` (Swiss) region:
+
+```yaml
+  ch_vd_lundi_du_jeune_federal:
+    # Monday after the third Sunday of September
+    arguments: year
+    ruby: |
+      date = Date.civil(year,9,1)
+      # Find the first Sunday of September
+      until date.wday.eql? 0 do
+        date += 1
+      end
+      # There are 15 days between the first Sunday
+      # and the Monday after the third Sunday
+      date + 15
+```
+
+The logic itself is not hard to follow but coming up with a generic way to phrase this seems like a complex problem. Every attempt that was made devolved into very complex parsers of nested `YAML` so that we correctly handled each new edge case that appeared. It was very slow going and the complexity was growing and growing.
+
+Additionally, having a complex `YAML` syntax for custom methods would require each downstream repository to implement the 'standard'. That seems pretty scary to think about maintaining.
+
+The other option is to just make each future language provide their own implementations.
+
+## Decision
+
+The decision is to simply require language-specific implementations of custom methods. Since all custom methods are currently in `ruby` we are changing every `source` field to `ruby`. In the future new languages will need to provide their own implementations. For example, we could add a `golang` or `swift` section next to the existing `ruby` section.
+
+There are three significant advantages:
+
+ - It is very easy to understand
+ - All holidays using custom methods have tests so each downstream project will have built-in protection in case a bug is introduced in only one language implementation
+ - It is very easy to implement for the current `ruby` implementation (which is our only project currently)
+
+There are significant downsides:
+
+ - Possible divergence between languages due to separate implementations, causing confusion and frustration
+ - More pressure on maintainers to handle the various implementations, ensuring they can build without issues when new custom methods are added
+ - Confusion for new contributors who may only be comfortable in a single language
+ - New downstream languages will have a higher hurdle to overcome since they will need to implement the existing logic in their own language
+
+In the end I don't want to hold things up because of _possible_ new language implementations that might show up in the future. I personally want to create a new `golang` version of `holidays` but beyond that maybe no one else will consume these definitions!
+
+If the `holidays` projects become wildly popular in the future and this becomes a huge problem then I can address it with the (presumably huge) community to find a solution.
+
+## Consequences
+
+We might lose contributions due to confusion or fear.
+
+We might burn out maintainers if the juggling of languages becomes too much of a burden.
+
+This puts more pressure for the completion of an updated [test framework](https://github.com/holidays/definitions/issues/42) for downstream repositories.
+
+## Status
+
+Accepted.

+# ADR 2: Year ranges syntax update
+
+## Context
+
+#### Original year range behavior
+
+Starting in [v3.2.0](https://github.com/holidays/holidays/releases/tag/v3.2.0) of the ruby gem [\[1\]](#footnote-1) we have had the ability to specify year ranges for specific holidays. This allows for a holiday
+to only be considered 'valid' or 'active' based on specific criteria surrounding years. The available criteria were:
+
+* `before` - holiday only valid if it takes place on the target year or before
+* `after` - holiday only valid if it takes place on the target year or after
+* `limited` - holiday only valid if it takes place on at least one of an array of target years (e.g. [2002, 2004])
+* `between` - holiday only valid if it takes place between an inclusive year range (e.g. 2002..2004)
+
+This change added useful functionality and its use has since spread to multiple regions.
+
+#### Confusion about criteria behavior
+
+On January 24th, 2019 [an issue was opened](https://github.com/holidays/definitions/issues/117) expressing that the `before` and `after` criteria were named in a confusing manner since it was not clear whether they operated inclusively or exclusively on the target year.
+
+As an example, the value `after: 2018` could be construed by some to mean the holiday is valid starting in 2019 and onward. In reality the current implementation is that the holiday is valid starting in 2018 itself and onward.
+
+While this is ultimately up to individual perception it is true that the current names do not provide strong guidance on how the definition will behave.
+
+## Decision
+
+The [above issue](https://github.com/holidays/definitions/issues/117) also contained a proposal to make the following changes:
+
+* Rename `before` to `until`
+* Rename `after` to `from`
+
+These names give a clearer understanding of the desired behavior as `until` and `from` are more generally understood to indicate inclusivity rather than exclusivity.
+
+If we take the example from above and make the change then the value `from: 2018` would intend for the holiday to be valid/active starting in 2018 and onward.
+
+#### Additional changes
+
+While looking into the above issue I noticed two important things that will also be addressed alongside the above changes:
+
+* The definition validator does not currently prevent users from specifying multiple selectors at a time for a `year_ranges` entry and we perform no validation that these selectors do not conflict with one another.
+* The `between` key currently accepts a string representation of a Ruby range (e.g. '2008..2012'). While this was not causing any issues today we would like to remove all Ruby-specific values from our definitions so that other languages could more easily parse them.
+
+To that end the following changes will also be made:
+
+* Update the definition validation to only allow a single selector per `year_ranges` entry and update all definitions to match. This will result no behavior changes but will make clear the expected behavior.
+* `between` will no longer accept a ruby-like range string but instead require explicit `start` and `end` keys with integer values representing a year.
+
+## Consequences
+
+This change will require changing multiple files and wll result in a major semantic version bump for the definitions. In addition we will also need to make a similar breaking change in all consuming apps.
+
+There are mitigating factors, however. There are only a handful of existing definitions that use the `before`, `after`, or `between` keys and the only consuming app is the [ruby gem](https://github.com/holidays/holidays). This means our affected code is relatively small.
+
+Additionally there was already a plan in place to perform an unrelated breaking change in the gem. This means that we can bundle these breaking changes together and minimize the amount of version churn.
+
+## Status
+
+Accepted.
+
+## Footnotes
+
+##### footnote-1
+
+In the original `holidays` ruby library all definitions were housed in the same directory. The definitions were split into a separate repository starting with [holidays gem v5.0.0](https://github.com/holidays/holidays/blob/master/CHANGELOG.md#500).

+# Great Britain/United Kingdom holiday definitions for the Ruby Holiday gem.
+#
+# Including England, Wales, Scotland, N. Ireland, the Isle of Man, Guernsey

+#
+# Updated: 2019-02-10
+# Sources:

+#
+# Notes:
+# - Jersey, Guernsey and the Isle of Man are encode with both their ISO 3166-1 and ISO 3-3166-2 codes.
+# - England and Wales together should be encoded as [gb_eng, gb_wls, gb_eaw...]
+# - For :gb_sct, St. Andrew's Day is 'informal' 2006 and earlier but a bank holiday from 2007 on.

+# CHANGES:
+#  2010-12-25: Initial version by Tatsuki Sugiura <sugi@nemui.org>
+#  2014-11-09: Added substitute holiday by Yoshiyuki Hirano <yoshiyuki.hirano@henteco-labs.com>
+#  2015-05-10: Non-Monday substitute holidays by Shuhei Kagawa <shuhei.kagawa@gmail.com>
+#  2015-12-15: Added mountain day by Tsuyoshi Sano <ttwo32@gmail.com>
+#  2016-03-26: Updated to match new custom method signature. See below for more. Phil Trimble <philtrimble@gmail.com>
+#  2019-02-10: Changing usage of 'year_ranges.after' to 'year_ranges.from' and 'year_ranges.before' to 'year_ranges.until', see https://github.com/holidays/definitions/issues/117
+#
+# MAINTAINER NOTE: This is the most complex set of custom date methods in the entire
+# project, mainly surrounding the idea of 'substitute' holidays. Since this is
+# the only one that is this complex I have settled on a less-than-ideal solution.
+# It is overly verbose and not easy to follow. It will be a target for refactoring
+# in the near future.

+# How to contribute
+
+There are multiple ways to help! We rely on users around the world to help keep our definitions accurate and up to date. In addition, pull requests to address bugs or implement new features are always welcome.
+
+## Code of Conduct
+
+Please read our [Code of Conduct](../CODE_OF_CONDUCT.md) before contributing. Everyone interacting with this project (or associated projects) is expected to abide by its terms.
+
+## General note
+
+The definitions for this project are housed in a submodule. When pulling this repo please make sure to run `git clone --recursive git@github.com/holidays/holidays`
+or, if you forgot to do so, run `make update-defs` so that all of the submodule data is pulled correctly.
+
+## For definition updates
+
+Our definitions are written in YAML. They are housed in a [separate repository](https://github.com/holidays/definitions) so that they can be used by tools written in other languages. You can find a complete guide to our format in the [definitions SYNTAX guide](https://github.com/holidays/definitions/blob/master/doc/SYNTAX.md).
+
+In this ruby project we take the YAML definitions and generate final ruby classes that are loaded at runtime for fast calculations.
+
+Once you have a good idea on what you want to change, please see the [CONTRIBUTING guide](https://github.com/holidays/definitions/blob/master/doc/CONTRIBUTING.md) in the `definitions` repository.
+
+The idea is that if the validation passes on the other repo then you shouldn't have to worry about generating and testing here. We'll see how that goes!
+
+Once that PR is accepted the maintainers of this project will be responsible for generating the updated definitions here and releasing a new gem. Don't worry about versioning, we'll take care of it!
+
+#### Testing out your definitions locally
+
+As mentioned above we use a git submodule for the definitions. Sometimes you might want to manually test out how this ruby project will behave with your changes. To facilitate that we provide some commands for pointing the definitions submodule to your fork/branch.
+
+To point at your fork/branch:
+
+```sh
+make clean-defs
+BRANCH=<branch-name> USER=<user> make point-to-defs-branch
+```
+
+Example:
+
+```sh
+make clean-defs
+BRANCH=issue-24 USER=ppeble make point-to-defs-branch
+```
+
+This will pull everything down for the latest commit on that fork/branch. When you are done testing and want to point back at the master definitions:
+
+```sh
+make clean-defs
+make point-to-defs-master
+```
+
+## For non-definition functionality
+
+* Fork this repository
+* Make your changes. Don't forget to run `make test` to execute the test suite!
+* Create a PR pointing back to `master`
+
+Don't worry about versioning, we'll handle it on our end.
+
+*Tests are required*. If your PR results in lower test coverage then it will not be accepted.
+
+## Local development helpers
+
+We have included a few handy tasks to help you troubleshoot and test:
+
+* `make test` - runs the entire suite
+* `bundle exec ruby <test-file-to-run>` - runs just the tests in the specified file
+* `REGION=<region> make test-region` - runs the tests for just that region
+* `make console` - launches an IRB session with the 'holidays' gem loaded for quick testing
+* `make update-defs` - runs the appropriate git submodule commands to pull the latest definitions
+* `make clean-defs` - removes the definitions submodule, useful for switching between a fork and the main definitions repository
+* `BRANCH=<branch> USER=<user> make point-to-defs-branch` - updates your definitions submodule to point at a fork/branch
+* `make point-to-defs-master` - updates your definitions submodule to point back at the `holidays/definitions` repo and master branch

+# Maintainers guide
+
+This document outlines the process of releasing an update to the `holidays` gem. This update could
+include any (or a combination of) the following:
+
+* definition updates from the [definitions](https://github.com/holidays/definitions) repository
+* bug fixes
+* additional functionality
+
+### semver
+
+This gem operates under the rules of [semver](http://semver.org/). The decisions on what constitutes a major,
+minor, or patch version update fall on the maintainer. If in doubt, follow these rules:
+
+* Will this change mean that users will be REQUIRED to make a code change? If so then it is a major version bump. This includes dropping supported versions of ruby!
+* Will this change mean that users might see a definition/behavior change but won't need to modify their own code? If so then it is as minor version bump
+* Will this change mean that a bug, either in code or definitions, will be fixed? If so then it is a patch version bump
+
+*@ppeble editor note*: I am pretty aggressive when it comes to version bumps! If the slightest functionality has changed then
+I consider it a minor version bump, if ANY consumer code has to change then I consider it a major version bump. I don't care
+if we get up to version 250, the version number doesn't matter. Communicating the effort required in updating is what matters!
+
+### Who this document is for
+
+This document is for maintainers that have merge access to this repository. These maintainers may or may not have access to the upstream
+[definitions](https://github.com/holidays/definitions) repository.
+
+Please note that a core contributor must provide the relevant Github access so that you can perform merges. If you have any issues
+please contact the [core members](https://github.com/orgs/holidays/teams/core/members) for assistance.
+
+### Setup
+
+This guide assumes that you have forked the repository in Github. If you require assistance in this please contact the core members listed above.
+
+You will need upload access to rubygems.org in order to publish gems. Contact a [core member](https://github.com/orgs/holidays/teams/core/members) for assistance.
+
+### Release Overview
+
+A release could contain one or more of the following:
+
+* definition updates - these are rule updates pulled from https://github.com/holidays/definitions. These changes are not
+language specific and will most likely require local regeneration of compiled rules.
+* functionality additions - this is new functionality in this repository that uses the existing definitions
+* bug fixes - these are bug fixes in this repository
+
+It is up to the maintainer to determine what needs to be updated. We will attempt to outline the various scenarios in the
+sections below.
+
+### Release flow
+
+* Does this update require definition updates? If YES, then:
+  * Pull the latest `master` version of this ruby repository and run `make update-defs`. This will grab the latest version from the [definitions](https://github.com/holidays/definitions) repository. Run `git diff` to verify that the version of the submodule for the definitions matches the latest commit in the [definitions](https://github.com/holidays/definitions) repo.
+  * Run the `make generate` command. This will 'recompile' the ruby sources with the latest definitions.
+  * Run `make test` and ensure that all of the tests pass. If any tests fail then do *not* merge and contact a [core member](https://github.com/orgs/holidays/teams/core/members) for assistance.
+  * If all of the tests pass, update the `lib/holidays/version.rb` file to the new version. Reference the above [semver](http://semver.org/) rules for how to update versions.
+  * Make a branch on your fork and update the [CHANGELOG](../CHANGELOG.md) to reflect the latest changes. You do not need to put in all of the definition changes in this update, you can simply reference the other repository. See other entries in the CHANGELOG for examples.
+  * Open a PR against the new branch and merge it (another maintainer will need to review before you can merge)
+  * Once the branch is merged, pull down the latest master from Github and run `make build`. This will generate a new `gem` file with the new version. The new version number is pulled from the above `version.rb` update.
+  * If the build was successful then you can run the following to push up to rubygems.org: `GEM=<gem> make push`. Example: `GEM=holidays-6.2.0.gem make push`
+* Does this update require functionality additions or bug fixes? If YES, then:
+  * Run `make test` and ensure that all of the tests pass. If any tests fail then do *not* merge and contact a [core member](https://github.com/orgs/holidays/teams/core/members) for assistance.
+  * If all of the tests pass, make a branch on your fork and update the [CHANGELOG](../CHANGELOG.md) to reflect the latest changes.
+  * Update the `lib/holidays/version.rb` file to the new version. Reference the above [semver](http://semver.org/) rules for how to update versions.
+  * Open a PR against the new branch and merge it (another maintainer will need to review before you can merge)
+  * Once the branch is merged, pull down the latest master from Github and run `make build`. This will generate a new `gem` file with the new version. The new version number is pulled from the above `version.rb` update.
+  * If the build was successful then you can run the following to push up to rubygems.org: `GEM=<gem> make push`. Example: `GEM=holidays-6.2.0.gem make push`
+
+You are done! The latest version should be uploaded to rubygems.org. You can go to view the [holidays page](https://rubygems.org/gems/holidays) to verify that the latest version is available.
+
+It is totally acceptable to do both functionality AND definition updates in a single release. Simply combine both sets of rules into a single branch for your update.
+
+### Troubleshooting
+
+The biggest hurdle in this repository is that [upstream definition](https://github.com/holidays/definitions) changes will
+result in failures in existing tests and it will not be because of ruby issues but rather upstream issues. If you notice any test failures
+that seem to be specific to certain regions then look at recent changes in that other repository. If there were changes there then the odds
+are that there are issues in the definition-specific tests. This is most likely not a language (i.e. ruby) specific issue.
+
+It is a known issue that the definitions do not have a good set of self-tests to ensure that they are internally consistent. This means that a failure in this
+repository could NOT be related to ruby specifically. It could be that the 'tests' specified in in the YAML files are incorrect! If you encounter errors here
+make sure that you don't assume that it is just a ruby error that is causing the issues!

+# Integration tests
+
+These tests are dependent on the files in /definitions (and, by proxy, /lib/generated_definitions).
+It is possible that these tests will break because of 'unrelated' definition changes. The code
+behind these changes could still be good but since the definitions changed we could see failures.
+
+These are not unit tests. This is not testing whether specific internal code is working. These are
+tests from the consumer perspective. You must recognize that this could fail because of code
+changes unrelated to definition changes.
