Extends
Calendar.
Construct a new Persian astronomical (Hijjri) calendar object. This class encodes
information about a Persian calendar. This class differs from the
Persian calendar in that the leap years are calculated based on the
astronomical observations of the sun in Teheran, instead of calculating
the leap years based on a regular cyclical rhythm algorithm.
Defined in: PersianCal.js.
