JDF - Jalali Date [and Time] functions

The Jalali calendar is a solar calendar that was used in Iran (Persia), variants of which today are still in use in Iran as well as Afghanistan. It gains approximately 1 day on the Julian calendar every 128 years. The tropical Jalali calendar (Persian: گاهشماری جلالی or تقویم جلالی‎), which inherited some aspects from the Yazdgerdi calendar, was adopted on 15 March 1079 by the Seljuk Sultan Jalal al-Din Malik Shah I (for whom it was named), based on the recommendations of a committee of astronomers, including Omar Khayyam, at the imperial observatory in his capital city of Isfahan. Month computations were based on solar transits through the zodiac, a system integrating ideas taken from Hindu calendars[citation needed], read more on Wikipedia.

Calendar conversion is based on the algorithm provided by Roozbeh Baabakaan.
