.. highlight:: php

Proleptic Gregorian calendar is the default calendar of the library.

Years are assumed to be in the astronomical notation. (1 AD = 1, 1 BC = 0, 2 BC = -1)

The date range is -5884323-05-15 to 5874898-06-03 for a 32-bit system

and -25252734927771267-04-30 to 25252734927761842-06-20 on a 64-bit system.

Factories

=========

You can create an instance of date from either components or a ``Y-m-d`` string format (years can be negative)::

    <?php

    use Arokettu\Date\Date;

    use Arokettu\Date\Month;

    $date = Date::create(2012, 12, 21);

    // or use a month object

    $date = Date::create(2012, Month::December, 21);

    // or parse Y-m-d

    $date = Date::parse('2012-02-21');

    // years may be negative and leading zeroes are ignored

    $date = Date::parse('-5000-2-000001'); // works too!

Getters

=======

There are getters for day, month, year, string representation and array representation::

    <?php

    use Arokettu\Date\Date;

    $date = Date::parse('2012-12-21');

    $date->getDay(); // 21

    $date->getMonth(); // Month::December

    $date->getMonthNumber(); // 12

    $date->getYear(); // 2012

    $date->getDateArray(); // [$y, $m, $d]: [2012, 12, 24]

    $date->toString; // Y-m-d: 2012-12-24
