Are you sure you want to hear about how to convert a date in Jalali (Persian) Calendar to Gregorian Calendar? Anyway, my date of birth being fixed in our calendar can be observed in three different days in Gregorian calendar, depending on which year that is. (Feb. 28th, Feb 29th, Mar. 1st). The reason is that we observe leap years quite different, more accurately with seasonal changes. No one cares for their Gregorian date of birth until they get their passport and those freaks have got mine wrong all these years, apparently in that year that I was born, the day had fallen on March 1st instead of Feb 28...
