Yasumi

Yasumi (Japanese for Holiday) is an easy PHP library to help you calculate the dates and names of holidays and other special celebrations from various countries/states. Many services exist on the internet that provide holidays, however are either not free or offer only limited information. In addition, no complete PHP library seems to exist today that covers a wide range of holidays and countries, except maybe PEAR's Date_Holidays which unfortunately hasn't been updated for a while.

The goal of Yasumi is to be powerful while remaining lightweight, by utilizing PHP native classes wherever possible. Yasumi's calculation is provider-based (i.e. by country/state) so it is easy to add new holiday providers that calculate holidays. The methods of Yasumi can be used to get a holiday's date and name in various languages.

Highlights

• Simple API
• Use of Providers to easily extend and expand new Holidays
• Common Holiday Providers
• Global Translations
• Implements ArrayIterator to easily process a provider's holidays
• Fully documented
• Fully Unit tested
• Framework-agnostic
• Composer ready, PSR-2 compliant

Currently the following holiday providers are implemented:

• Japan
• Netherlands
• Belgium
• USA

System Requirements

You need PHP >= 5.4.0 to use azuyalabs/yasumi but the latest stable version of PHP is recommended.

Installation

Install azuyalabs/yasumi using Composer.

$ composer require azuyalabs/yasumi

Testing

Yasumi has a PHPUnit test suite. To run the tests, run the following command from the project folder:

$ phpunit

The tests are organized in some test suites to make testing a bit more easier:

• Base : For testing the base functionality of Yasumi
• Japan : For separately testing the Japan Holiday Provider
• Netherlands: For separately testing the Netherlands Holiday Provider
• Belgium : For separately testing the Belgium Holiday Provider
• USA : For separately testing the USA Holiday Provider

<?php
// Require the composer auto loader
require 'vendor/autoload.php';

use Yasumi\Yasumi;

// Use the factory to create a new holiday provider instance
$holidays = Yasumi::create('USA', 2015);

// Get the number of defined holidays
echo $holidays->count() . PHP_EOL;
// 11

// Get a list all of the holiday names (short names)
