Hijri Calendar Class is group of functions that gets the Hijri Calendar and converts it to other calendars

This class contains functions work similar to calendar functions in PHP but it is work with Hijri Calendar. The Class has two algorithms to calculate the Hijri Date

Hijri Tabular Algorithm:
This algorithm was used by past to simplify the Hijri Calendar calculation, The result of this algorithm identical to Hijri Calendar in Microsoft programs and "The Calendar of Centuries-تقويم القرون" book of "Saleh Alojiry صالح العجيري".
Umm Al-Qura Algorithm(Recommended).
This is the official calendar of Saudi Arabia Kingdom based on astronomical calculation which published in the site http://www.ummulqura.org.sa, the range of this algorithm from year 1318 to 1500, the start of hijri months of this algorithm can be adjusted by using CalendarAdjustment Class see file adjuster.php in folder example as sample
to set the default setting of this class use $hijri_settings variable which is an array with this sample structure: 
$hijri_settings=array(
'langcode'=>'ar',
'defaultformat'=>'_j _M _Yهـ',
'umalqura'=> TRUE,
'adj_data'=> array(1426 => 57250, 1429 => 57339,),
'grdate_format' => 'j M Y',
);
