Carbon Extension to calculate German Holidays

Installation

Install the library using composer:

composer require fgits/carbon-german-holidays

Usage

General usage by example:

<?php
require_once 'vendor/autoload.php';

use Fgits\CarbonGermanHolidays\CarbonGermanHolidays;

// Now you can Use CarbonGermanHolidays like Carbon
// eg.: CarbonGermanHolidays::instance() etc.

// Create some instance
$instance1 = CarbonGermanHolidays::createFromDate(2019, 01, 01);
$instance2 = CarbonGermanHolidays::createFromDate(2018, 12, 24);

// Check if the instance is a German Holiday
echo $instance1->isGermanHoliday(); // true 
echo $instance2->isGermanHoliday(); // false

echo $instance2->isGermanHoliday(CarbonGermanHolidays::ALL_STATES_ALL_DAYS); // true, cause ALL_STATES_ALL_DAYS includes some more special days

// Get holiday names for instance
echo $instance1->getGermanHolidaysForDay(); // array('Neujahr') 
echo $instance2->getGermanHolidaysForDay(); // array() 

echo $instance2->getGermanHolidaysForDay(CarbonGermanHolidays::ALL_STATES_ALL_DAYS); // array('Heiligabend'), cause ALL_STATES_ALL_DAYS includes some more special days

Getting holidays for specific German states:

<?php
// import class etc, see above.

// Create some instance
$instance1 = CarbonGermanHolidays::createFromDate(2019, 11, 01);

// Check if the instance is a German Holiday
echo $instance1->isGermanHoliday(CarbonGermanHolidays::BRANDENBURG); // true 

// Get holiday names for instance
echo $instance1->getGermanHolidaysForDay(CarbonGermanHolidays::BRANDENBURG); // array('Reformationstag') 

Support for some other special days:

In Germany, eg. the 24th of December is not a public holiday. But in my opinion its a special day, you may want to check for. For this case, the class offers some additions to the German states:

<?php
// import class etc, see above.

// Create some instance
$instance1 = CarbonGermanHolidays::createFromDate(2018, 03, 29); // which is "Gründonnerstag"

// Check if the instance is a German Holiday
echo $instance1->isGermanHoliday(CarbonGermanHolidays::SPECIAL_DAYS_2); // true 

// Get holiday names for instance
echo $instance1->getGermanHolidaysForDay(CarbonGermanHolidays::SPECIAL_DAYS_2); // array('Gründonnerstag') 

For all supported days have a look at the constants in the CarbonGermanHolidays class and the function CarbonGermanHolidays::getHolidays
