yasumi

A new release for the new year! In addition to numerous improvements, bug fixes and code enhancements, this release also includes a new country: Mexico. Also support for PHP 7.4 (and older) is dropped and support for PHP 8.3 is added.

Below you will find a summary of the most significant changes. For more details, please check the CHANGELOG file.

  observed. #311 (ihmels)

  and Christmas Day.
  #314 (barami)

Resolved Issues

  and United Nations Day were incorrectly calculated during for certain periods. #314 (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 (rChassat)

Removed

• Denmark will abolish Great Prayer Day ('store bededag') from 2024. #308 (c960657)

Full Changelog: https://github.com/azuyalabs/yasumi/compare/2.6.0...2.7.0

There is a fresh release at last! I really believe in releasing software as frequently as possible, yet I somehow neglected to do so for more than a year. Even though a lot of work was completed during that time, I was just unable to pick the ideal moment to make an official release.

Despite the fact that no new countries are included in this release, there are several upgrades, corrections, and refinements that make Yasumi 2.6 worthwhile to upgrade to.

Below you will find a summary of the most significant changes. For more details, please check the CHANGELOG file of this project or navigate to the v2.6 release blog post.

Implemented Enhancements

• Bank holiday for King Charles III’s Coronation in the United Kingdom. #305 (Freshleaf Media)
• Bank holiday for Queen Elizabeth II’s State Funeral on September 19, 2022, for the United Kingdom. #287 (Freshleaf Media)
• National Day of Mourning for Australia. #288 (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 (Jozef Grencik)

Resolved Issues

• Liberation Day for The Netherlands is only an official holiday every 5 years #280 (Daan Roet).
• 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.
• 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 (Anna Damm).
• 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.

It is that time again; the time for a new release!

We have two more countries, and for a few countries new holidays are added, or regulations have been revised. Even more importantly, support for PHP 7.3 has been dropped, so all the more reason to upgrade to version 2.5.

The documentation site has undergone a few changes, specifically to support readers with disabilities. And lastly, head over to GitHub Discussions to ask questions or share your ideas.

A couple of months after the successful v2 release, a new minor release is available as of today. Yasumi v2.1 addresses mostly a few issues for the Japan Holiday Provider and some other bug fixes.

Implemented enhancements

• As the Japanese Emperor will abdicate the throne on May 1st 2019, the holiday of the Emporers Birthday will change to February 23rd from 2020 (No holiday in 2019). In addition, Coronation Day and the Enthronement Proclamation Ceremony will be extra holidays in 2019. #130 (cookie-maker)

• Visibility of internal class functions to 'private'. These are to be used within the class only and should not be public.

• Tests for Bremen, Lower Saxony and Schleswig Holstein (Germany) also celebrated Reformation Day in 2017. The unit tests were failing as it didn't account for that.

Almost a year has passed since the release of v1.8.0, but finally it is here: Yasumi v2.0.0!

Upgraded entirely to PHP version 7 with PHP 7.1 being the minimum required version. Base code and all unit tests have been reworked to compatibility with PHP 7. This also means support of PHP 5 has now come to an end.

More details can be found in the blog entry here: Welcome Yasumi version 2!

• Fixed issue for summertime in Denmark in 1980. By default summertime in Denmark is set for the last day of March since 1980, however in 1980 itself, it started on April, 6th.
• Fixed spelling issue in the Swedish translation. #97 (c960657)
• Fixed spelling issues in the Danish translation. #96 (c960657)

Yasumi version 2.0 has been released (and v1.8.1)!

With the release of Yasumi v2.0.0 supporting only PHP version 7.1 (or higher), support for PHP 5 in Yasumi has ended (Sorry!).

This 1.8.1 bug fix release has been made available for those that still are on PHP 5 (or are in the process of upgrading to PHP 7). It only includes some serious/critical bug fixes discovered since version 1.8.0 and no new countries have been added for example.

Please be aware that all new development will be done from v2.0.0 onwards (in the 'develop' branch). The 'support/1.8.x' branch has been created for critical bug fixes only.

Changes

• Added PHP 7.2 and 7.3 to the TravisCI configuration.
• Changed Japanese holiday for the 2020 Olympic Games. Marine Day, Mountain Day and Health And Sports Day. #113
• Changed translation for Norway's national day. #98

Resolved issues

• Except New Years Day, all holidays for Russia didn't have the locale parameter in place, causing Yasumi to use the fallback locale ('en_US').
• Fixed spelling issue in the Swedish translation. #97
• Fixed spelling issues in the Danish translation. #96
• Fixed German Easter Sunday and Pentecost Sunday holidays (not nationwide, only in Brandenburg). #100
• Fixed BetweenFilter to ignore time part and timezone. #101
• Fixed bug in provider list generation related to variable order of files returned by the filesystem #107
• Fixed issues that assertNotHoliday() skips rest of test
• Type cast to integer as Yasumi::create() requires an integer.
• Changed access to static variables with 'self'. Accessing with 'static' can lead to possible sub-classes.
• Corrected date parameter to be of DateTime (instead of DateTimeInterface) as the parameter object needs to be a direct instance.
• Changed way to get current year so value is an integer (as required by the class). PHP's date function is intended for formatting and returns a string type as such.
• Corrected test using different start year to avoid incorrect assertion.

Yasumi v1.8.0 is now available as of Wednesday, February 21st supporting Russia and Estonia thanks to the work of Gedas Lukošius.

As already announced in my previous post, 1.8.0 will be the last release to officially support PHP5.x. I think it's about time that Yasumi will fully support PHP7 using its performance improvements.

Next to Russia and Estonia being part of the family, 1.8.0 includes a good number of fixes and changes as well.

Implemented enhancements:

• Added a function that can remove a holiday from the holidays providers (i.e. country/state) list of holidays. This function can be helpful in cases where an existing holiday provider class can be extended but some holidays are not part of the original (extended) provider.
• Changed various functions that have a date parameter to support now objects implementing the DateTimeInterface and objects of the DateTimeImmutable type.
• Added support for countries where the weekend definition (start and end day) differs from the global definition (Saturday and Sunday).
• Holiday Provider for Russia. #72 (lukosius)
• Holiday Provider for Estonia. #71 (lukosius)
• Added Scrutinizer integration.
• Locale List updated based on CLDR version 32.
• Added PHPStan static analysis tool to Travis CI #88 (lukosius)
• Various inline documentation enhancements. #87 (lukosius)
• Removed unnecessary typecasts and if-construct. #87 (lukosius)
• Updated inline documentation to include correction Exception throws.
• Removed unnecessary NULL checks.

Resolved Issues:

• Fixed Brazilian Carnaval Day and added Ash Wednesday to Brazilian Holidays. #92 (glauberm)
• Yasumi listed 01.04.2018 (Easter Sunday) for Spain as an official holiday, however it is not recognized as such. Fix made that recognizes Easter Sunday as being observed (in all regions). #86 (Bastian Konetzny)
• Corrected reference to the Holiday Provider's ID to be static.
• Changed weekend data property into constant as it is not dynamic (runtime).
• Corrected the name translation test for the Restoration of Independence Day (Portugal). The test didn't account for the fact that this holiday was abolished and reinstated at some time.
• Corrected unit test for Geneva (Switzerland) as the jeune Genevois day was incorrectly asserted as a regional holiday.
• Corrected the count logic so that in case a holiday is substituted (or observed), it is only counted once.
• Dropped unnecessary arguments of some methods in various Holiday Providers.
• Corrected Japanese "Green Day" and "Children's Day" to use "Hiragana" instead of Kanji. #80 (cookie-maker)

A new release was long overdue and v1.7.0 has some nice enhancements... Four new countries have been added (Latvia, Lithuania, Hungary and Switzerland) making the total of holiday providers 96! (31 countries and 65 sub-regions).

Instead of giving the country name as a parameter, you can now also use the ISO3166_2 code to instantiate a Holiday object, which in some cases makes more sense. Also, all filters implement the Countable interface so you can use the ->count() method, which will return the correct number of (filtered) holidays.

Heads up! v1.7.0 will be the last release supporting PHP5.x. PHP7 has been out for a long time and Yasumi can definitely benefit from the new features in PHP7. Likely the PHP7 only branch will start as v2.0.0.

As always a big thanks to all the contributors!

Implemented enhancements:

• Holiday Provider for Latvia. #70 (lukosius)
• Holiday Provider for Lithuania. #67 (lukosius)
• Holiday Provider for Hungary. #57 (AronNovak)
• Holiday Provider for Switzerland. #56 (qligier)
• All filters implement the Countable interface allowing you to use the ->count() method. #77
• 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 (huehnerhose)
• Missing translations (de_DE) for Easter Sunday and Whitsunday. #60 (IceShack)
• Made calculate method public and use of proper camel casing. #73 (patrickreck)
• Upgraded Faker Library to version 1.7
• Renamed the holiday type NATIONAL to OFFICIAL. Subregions may have official holidays and the name NATIONAL doesn't suit these situations. #65
• Upgraded PHP-CS-Fixer to version 2.6

Resolved Issues:

• Corrected Geneva (Switzerland) unit test to ensure some holidays that are established at a particular year are handled as such.
• Repentance Day is an official holiday in Saxony (Germany) #63
• Corrected the Easter Sunday translation for Austria (de_AT) #66
• Corrected Hungary unit test to ensure holidays that are established at a particular year are handled as such.
• Added missing Summer Bank Holiday for the United Kingdom. #64

This bugfix release addresses some minor annoying issues, so unfortunately no new features this time.

Implemented enhancements:

• Moved Reformation Day to Christian Holidays as it is not only celebrated in Germany.
• Added missing unit tests for the German Unit Day for each German state.

Resolved issues:

• Fixed Christmas Day and Boxing Day for the United Kingdom. A substitute bank holiday is now created for both Christmas and Boxing Day when either of those days fall on a weekend. #48 (joshuabaker)
• Renamed 'en_US' translation for the Second Christmas Day (from ‘Boxing Day’ to ‘Second Christmas Day’: Boxing Day concept does not exist in the US). #53 (AngelinCalu)
• Created fallback calculation of the easter_days function in case the PHP extension 'calendar' is not loaded. #55 (stelgenhof)
• Added missing unit tests for Reformation Day as in 2017 it is celebrated in all German states for its 500th anniversary.
• Changed Travis configuration to use Composer-installed phpunit to avoid if any issues arise with globally installed phpunit.

We start the new year with a new release, in which we welcome Austria, Ireland, Romania and South Africa to the Yasumi family. Also Yasumi hit the 8000 mark in the first week of 2017: over 8000 times Yasumi has been installed already!

Again, thank you all for your contributions and fixes!

Implemented enhancements:

• Added Holiday Provider for Romania. #52 (AngelinCalu)
• Added Holiday Provider for Ireland. stelgenhof
• Added Holiday Provider for South Africa. stelgenhof
• Added Holiday Provider for Austria. stelgenhof
• Refactored the calculation of Orthodox Easter using the function from ChristianHolidays.php. #47 (AngelinCalu)
• Added 'en_US' translations for the Polish Independence Day and Constitution Day. #45 (AngelinCalu)

Resolved issues:

• The parameters of the isHoliday and isWorkingDay methods now allow for classes that derive from DateTime (like the very popular Carbon class). #49 (stelgenhof)

Being occupied with other projects is good but has the side effect some others don't get the attention they deserve (sorry Yasumi). However, happy to announce a new release of Yasumi with 4 new countries added and holiday providers for all the German states.

Yasumi now supports 62 holiday providers (23 countries and 39 sub-regions) and has over 1500 unit tests ensuring all holidays are calculated correctly.

Big thanks to all the contributors making Yasumi better and more complete!

• You can now also use your own holiday providers in addition to the included holiday providers. A very helpful improvement if Yasumi does not include your provider (yet), but you want to use yours! #29 (navarr)

Resolved issues:

• Carnival Day in Brazil was incorrectly set to be 47 days after Easter. Carnival Day begins Friday before Ash Wednesday (51 days to Easter). #36 (icaroce)

  with other API's for example.
• To determine a set of holidays between two dates you can now use the aptly named 'between()' method.

  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 (R2c)

• Fixed base test for some Spain/LaRioja as some holidays have been established only in a particular year, causing
  false failures in the unit tests.
• Running php-cs-fixer fix . --level=psr2 generated a massive list of changes, and broke unit tests. Added a custom
  .php_cs config file to adhere to the PSR-2 Coding Standards and resolve this issue. In addition the php-cs-fixer
  command to 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 #16 (badams)
