Fasli Jalal
Adherents of Zoroastrianism use three distinct versions of traditional calendars for Zoroastrian festivals, liturgical purposes, all derived from medieval Iranian calendars and ultimately based on the Babylonian calendar as used in the Achaemenid empire. ''Qadimi'' ("ancient") is a traditional reckoning introduced in 1006. ''Shahanshahi'' ("imperial") is a calendar reconstructed from the 10th century text ''Denkard''. ''Fasli'' is a term for a 1906 adaptation of the 11th century Jalali calendar following a proposal by Kharshedji Rustomji Cama made in the 1860s. A number of Calendar eras are in use: *A tradition of counting years from the Date of Zoroaster, birth of Zoroaster was reported from India in the 19th century.

The principal change was to space leap years differently so as to make the average calendar year 365.2425 days long, more closely approximating the 365.2422-day 'tropical' or 'solar' year that is determined by the Earth's revolution around the Sun. The rule for leap years is: There were two reasons to establish the Gregorian calendar. First, the Julian calendar assumed incorrectly that the average solar year is exactly 365.25 days long, an overestimate of a little under one day per century, and thus has a leap year every four years without exception. The Gregorian reform shortened the average (calendar) year by 0.0075 days to stop the drift of the calendar with respect to the equinoxes.See Wikisource English translation of the (Latin) 1582 papal bull '' Inter gravissimas''.
