# Changelog

All notable changes to this project will be documented in this file.

The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).

Changes related to the business logic of the holidays or their providers are listed first, followed by any technical or architectural
changes.

## [2.7.0] - 2024-01-02

- Extra checks in case date subtraction fails for some holiday providers.
- PHP 8.3 support for the unit test CI pipeline. [#328](https://github.com/azuyalabs/yasumi/pull/328) ([fezfez](https://github.com/fezfez))
- Add code styling rules to have a space after the `NOT` operator and mark parameters with a default null value as nullable.

### Changed

- Refactor the rules for calculating holidays in South Korea based on the history of holiday changes.
  ([#314](https://github.com/azuyalabs/yasumi/issues/314)) [barami](https://github.com/barams@gmail.com)
- Update links to related documentation in the South Korea provider's note and added links to conversion utilities.
  [\#314](https://github.com/azuyalabs/yasumi/pull/314) ([barami](https://github.com/barami))
- Optimize the method for the Emperor's birthday calculation in Japan.
- For Croatia, extract Day of Antifascist Struggle calculation to a private method and simplify Statehood Day calculation
  to make it more concise.
- Simplify the conditions for the Coming of Age day (Japan) calculation.
- Simplify the calculation of Carnival in Argentina, Brazil and the Netherlands to reduce duplication.
- Avoid silent exceptions by throwing a new one from the previous exception.

### Fixed

- For South Korea, some of the past dates for Buddha's Day, Chuseok, Armed Forces Day
  and United Nations Day were incorrectly calculated during for certain periods. [\#314](https://github.com/azuyalabs/yasumi/pull/314) ([barami](https://github.com/barami))
- The holiday `twoDaysLaterNewYearsDay` of South Korea has been removed from 1990, however the unit test for the name
  and holiday type allowed the possible testing range to include the year 1990.
- New Years Day tests for South Korea were failing due to incorrect date checks.
- The Easter Date calculation resulted in wrong values for the year 2025, due to an incorrect rounding for the lunar
  correction when the calendar extension is not used. [#326](https://github.com/azuyalabs/yasumi/pull/326) ([rChassat](https://github.com/rChassat))

### Removed

- Denmark will abolish Great Prayer Day ('store bededag') from 2024. [#308](https://github.com/azuyalabs/yasumi/pull/308) ([c960657](https://github.com/c960657))
- Summertime and Wintertime in the Netherlands and Denmark as these can't be reliably established for historical dates and
  aren't true holidays in the context of Yasumi. Refer to this [discussion](https://github.com/azuyalabs/yasumi/discussions/321)
  for further details and rationale. [#322](https://github.com/azuyalabs/yasumi/pull/322)
- PHP 7.4 support.
- The PHP [Infection](https://infection.github.io/) test package as it was hardly used.
- Unit tests from a Git export to reduce the export size. [#323](https://github.com/azuyalabs/yasumi/pull/323) ([fezfez](https://github.com/fezfez))
- Checks for superfluous naming as we follow PER which supports such convention.
- MacOS from testing matrix as it returns errors (requires further investigation).

## [2.6.0] - 2023-04-27

### Added

- Bank holiday for King Charles III’s Coronation in the United Kingdom. [\#305](https://github.com/azuyalabs/yasumi/pull/305) ([Freshleaf Media](https://www.github.com/freshleafmedia))
- Bank holiday for Queen Elizabeth II’s State Funeral on September 19, 2022, for the United Kingdom. [\#287](https://github.com/azuyalabs/yasumi/pull/287) ([Freshleaf Media](https://www.github.com/freshleafmedia))
- National Day of Mourning for Australia. [\#288](https://github.com/azuyalabs/yasumi/pull/288) ([FuzzyWuzzyFraggle](https://www.github.com/FuzzyWuzzyFraggle)).
- In Japan, Marine Day was rescheduled to July 23 as the 2020 Tokyo Olympics took place. The rescheduled Marine Day for
  2021 was included, but not the original rescheduled day for 2020.
- Slovak translations for a couple of popular holidays. [\#298](https://github.com/azuyalabs/yasumi/pull/298) ([Jozef Grencik](https://www.github.com/jozefgrencik))
- All examples as shown on the documentation site as a convenience to developers who like to have all information in a
  single place.
- Included an `.editorconfig` file to maintain a consistent style for developers using different text editors.
- The `ext-intl` extension as a required extension. [\#306](https://github.com/azuyalabs/yasumi/pull/306) ([Freshleaf Media](https://www.github.com/freshleafmedia))
- An exception is thrown in case the time stamp of the start and end date in the `dateTimeBetween` method can't be established.
- Checks in case getting transition details or a date interval subtraction fails.

### Changed

- Adjusted the visibility of the `calculateSummerWinterTime` method to `private` as it is an internal method and
  shouldn't be accessible directly.
- Made the calculation for summer/winter time more defensive by adding a check that the timestamps are successfully created.
- Changed to use the `strtotime` function as `mktime` does not generate timestamps before 1970-01-01 (negative values),
  which is needed to determine winter/summertime before that.
- Refactored summer and winter time tests for Denmark and The Netherlands by introducing a base class holding the domain
  logic.
- Switched from `getShortName()` to `getName()` for the `ReflectionClass` created by the method `anotherTime()` in the
  `AbstractProvider` class. Using `getShortName` could result in a `ProviderNotFoundException` for some custom holiday
  providers, since the namespace is not fully qualified. This can happen, if you create a custom holiday provider.
  [\#292](https://github.com/azuyalabs/yasumi/pull/292) ([SupraSmooth](https://github.com/SupraSmooth)).
- Replaced the use of the `DateTime` class with `DateTimeInterface` (always use interface where possible).
- Use the preferred/idiomatic way of getting an immutable date from a mutable one. Added extra checks if modifying date
  methods are not successful.
- Split functions that generate random dates/years into a new trait to slim down the overgrown base trait.
- Code styling fixes and improvements.
- Upgraded dependencies to latest working versions.
- Improved and cleaned up numerous unit tests.

### Fixed

- Liberation Day for The Netherlands is only an official holiday every 5 years [\#280](https://github.com/azuyalabs/yasumi/pull/280) ([Daan Roet](https://github.com/droet)).
- Pentecost Monday in France was only recognized as an official holiday until 2004. Since 2004, it is considered a
  special holiday, a so called 'working holiday'. Hence, it is therefore classified as an observed holiday in Yasumi
  from 2004 and forward. [\#281](https://github.com/azuyalabs/yasumi/issues/281).
- The holiday of Epiphany (6th of January) was incorrectly categorized as `other` and changed to an official holiday in
  Baden-Württemberg, Bavaria and SaxonyAnhalt. [\#296](https://github.com/azuyalabs/yasumi/issues/296) ([Anna Damm](https://github.com/AnnaDamm)).
- The year 1988 was incorrectly omitted from observing the Emperor's birthday in Japan.
- The tests for Remembrance Day, Malvina's Day and National Sovereignty Day in Argentina were considered for all years;
  however, these have only been celebrated since their establishment.
- Tests for New Year's Day, Spring Bank Holiday, and May Day Holiday in the United Kingdom (England, Wales, Northern
  Ireland, and Scotland), as well as Battle of the Boyne in Northern Ireland, were considered for any calendar year;
  however, these are celebrated only since a particular calendar year.
- In version 2022f of the `tz` db, a correction for 1947 was made for the summertime transition in Denmark to April
  the 6th. Various corrections have been made to accommodate for change.
- The `ProviderInterface::getHolidays` has been re-added after it was erroneously removed. [\#277](https://github.com/azuyalabs/yasumi/pull/277) ([Jakub Wojtyra](https://github.com/jwojtyra-aterian)).
- Created the interface methods of the `ProviderInterface` that the abstract provider class implements. Since the return
  type of the Yasumi factory methods is now `ProviderInterface`, those missing methods generated errors, especially by
  static analysers.
- Changed the visibility of various class methods back to `protected`. The visibility was accidentally reduced during a clean-up
  of code. This caused these methods not being accessible any more when extending a provider class.

### Removed

- The `count` method from the `ProviderInterface` as the `AbstractProvider` class already implements the Countable interface.
- Unused `InvalidDateException` class and other unused imported classes.
- `tests` folder from analysis by PHPStan (the large number of files makes the analysis needlessly long).
- Redundant checks for empty arrays and types.
- Mutation testing from GitHub Actions, as currently the outcome is not actively used. Running mutation tests locally
  should be sufficient.

## [2.5.0] - 2022-01-30

  Provider. [\#255](https://github.com/azuyalabs/yasumi/pull/255) ([barami](https://github.com/barami)).
- Mothering Day for the United Kingdom [\#266](https://github.com/azuyalabs/yasumi/issues/266).

- All holiday providers now include a method that returns a list of external sources (i.e. references to websites,
  books, scientific papers, etc.) that are used for determining the calculation logic of the providers' holidays.

### Changed

- Revised rules to calculate substitution holidays of South Korea to apply the newly enacted law on June 2021. [\#255](https://github.com/azuyalabs/yasumi/pull/255) ([barami](https://github.com/barami)).

- `YasumiTestCaseInterface` was renamed to `HolidayTestCase` to better match the newly added `ProviderTestCase`
  interface.
- Updated codebase using PHP7.4 syntax features.
- Upgraded PHP CS Fixer to v3.

### Fixed

- All Saints Day (German: 'AllerHeiligen') was classified as `Other` for states celebrating this day. This was
  incorrect (or officially changed) and has been altered to `Official`
  . [\#263](https://github.com/azuyalabs/yasumi/issues/263)
- Corpus Christi (German: 'Fronleichnam') was classified as `Other` for states celebrating this day. This was
  incorrect (or officially changed)
  and has been altered to `Official`. [\#252](https://github.com/azuyalabs/yasumi/issues/252).
- The test for the USA in that juneteenthDay was considered for all years: it is only celebrated since 2021.
- Definition of Canada Day in Canada [\#257](https://github.com/azuyalabs/yasumi/pull/257) in that, Canada Day is July 1
  if that day is not Sunday, and July 2 if July 1 is a Sunday.([Owen V. Gray](https://github.com/adrx)).

  dropped in Yasumi once 7.1 has reached its end of life (December 2019).
- Code using class imports rather than Fully Qualified Class names.
- Upgraded to PHPUnit 8.
- Replaced the standard 'InvalidArgumentException' when an invalid year or holiday provider is given by a new exception
  for each of these two situations separately ('InvalidYearException' and 'ProviderNotFoundException'). This allows you

  class. [\#95](https://github.com/azuyalabs/yasumi/pull/95) ([qneyrat](https://github.com/qneyrat))
- Refactored the AbstractProvider::count method to use the newly added SubstituteHoliday class.

- Corrected reference to the Holiday Provider's ID to be static.

- Sometimes it is more convenient to be able to create a Yasumi instance by ISO3166 code rather than Yasumi's Holiday
  Provider name. A new function `createByISO3166_2` has been added to allow for
  that. [\#62](https://github.com/azuyalabs/yasumi/pull/62) ([huehnerhose](https://github.com/huehnerhose))
- Missing translations (de_DE) for Easter Sunday and
  Whitsunday. [\#60](https://github.com/azuyalabs/yasumi/pull/60) ([IceShack](https://github.com/IceShack))

  weekend. [\#48](https://github.com/azuyalabs/yasumi/issues/48) ([joshuabaker](https://github.com/joshuabaker))

## [1.5.0] - 2016-11-25

  . [\#38](https://github.com/azuyalabs/yasumi/pull/38) ([brucealdridge](https://github.com/brucealdridge))

  improvement if Yasumi does not include your provider (yet), but you want to use
  yours! [\#29](https://github.com/azuyalabs/yasumi/pull/29) ([navarr](https://github.com/navarr))
- Added Holiday Provider for
  Portugal. [\#44](https://github.com/azuyalabs/yasumi/pull/44) ([rvelhote](https://github.com/rvelhote))

- All Saints Day for Finland was incorrectly set for November 1st. The correct date is Saturday between 31 Oct and 6

- To determine a set of holidays between two dates you can now use the aptly named 'between()' method.

### Changed

- All Holiday Provider must now implement a code that will identify it. Typically, this is the ISO3166 code
  corresponding to the respective country or sub-region. This can help for purposes such as translations or interfacing
  with other API's for example.

### Fixed

- Fixed an issue with the unit test for the 'getProviders' method failing on Windows. Hardcoded unix-style directory
  separators have been replaced by
  DIRECTORY_SEPARATOR. [\#30](https://github.com/azuyalabs/yasumi/pull/30) ([navarr](https://github.com/navarr))
- Corrected a typo in the English translation for 敬老の日 (
  Japan) [\#22](https://github.com/azuyalabs/yasumi/pull/22) ([navarr](https://github.com/navarr))

  regions [\#5879133](https://github.com/azuyalabs/yasumi/commit/58791330ccf5c13b1626885921534c32866b7faf) ([R2c](https://github.com/R2c))

  Provider [\#9678bc4](https://github.com/azuyalabs/yasumi/commit/9678bc490e34980404ad5dc5b3d45a3c76a3ca0f) ([R2c](https://github.com/R2c))
- Corrected incorrect pathname reference \*BaseTestCase.php files ("Test" -> "test).
- Fixed issue for France as Good Friday and St. Stephens Day were defined as official holidays. These aren't national
  holidays and are only observed in the French departments Moselle, Bas-Rhin and Haut-Rhin. With this fix, these
  holidays have been removed from the France Holiday providers and new providers for the departments Moselle, Bas-Rhin
  and Haut-Rhin are added. [\#17](https://github.com/azuyalabs/yasumi/issues/17) ([R2c](https://github.com/R2c))

  .php_cs config file to adhere to the PSR-2 Coding Standards and resolve this issue. In addition, the php-cs-fixer
  command has been added to composer to run the fixers and on the CI server (Travis), meaning PR’s will need to be PSR2
  compliant before they can be merged. If any files do not pass, the build
  fails. [\#15](https://github.com/azuyalabs/yasumi/issues/15) [\#16](https://github.com/azuyalabs/yasumi/pull/16) ([badams](https://github.com/badams))
- Accidentally the timezone for Norway was set to "Europe/Copenhagen". This has been corrected to "Europe/Oslo"
