PHP Calendar Library : Factory

To simplify building calendars, a configurable factory is available : Popy\Calendar\Factory\ConfigurableFactory, and accept some options altering the building process.

<?php

use Popy\Calendar\Factory\ConfigurableFactory;

$factory = new ConfigurableFactory();

$calendar = $factory->build([
    /// options here
    'leap' => ...,
]);

?>

Leap year calculators

The Leap year calculators are used by converters to determine if a year is a leap one (obviously), the year length, and some other indexes. By default, the gregorian leap calculation is used, but many other are available, through the option 'leap' :

• noleap / none : no leap, as before the julian calendar
• julian / caesar : leap every 4 years
• modern / gregorian : leap every 4 years, but not every 100 years, but every 400 years
• futuristic : 1/4 - 1/100 + 1/400 - 1/2000 + 1/4000 - 1/20000
• persian / hijri : the persian cycle system
• von_madler : 1/4 - 1/128
• float : based on the float part of the year length

You can also provide any instance implementing the interface. All these classes also use the options 'year_length' (year duration in days, used as integer, exepct in the case of the float calculator) and 'era_start_year' (reference year from where to calculate dayIndex)
