12
Thank you.
The Jalali or hejira date is completely different from Garegorian date.
the year is 2012 in Garegorian but in jalali it is 1391 and in hejira it is 1433
The days in each month are totally different see below:
$g_days_in_month = array(31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31);
$j_days_in_month = array(31, 31, 31, 31, 31, 31, 30, 30, 30, 30, 30, 29);
i think all definitions and functions can be moved to language folder.
