To have these calendar functions, compile the PHP script using –enable-calender.
These calendar functions allow you to convert the date from one to another calendar. In Julian’s calendar, the count of days is not the same as it starts from January 1st, 4713 B.C and on the other hand, it is more accurate than working manually on the calendar.
