Iranian Calendar
Iranian official calendar is based on Solar year and March 21 is first of the Iranian month of Farvardin and beginning of Iranian New Year is called Nowruz ( Also in Iran, Lunar calendar is used for religious events and rituals, because migration date of Holy Prophet Mohammad(S) from Mecca to Madinah on 621AD is the beginning of the official Lunar and solar calendar. So by adding 621 to Iranian solar calendar year the Gregorian calendar year will be determined and vice versa. In month of Ramadan Iranian Muslims observe fasting and in Muharram they mourn for the martyrdom of Imam Hussein, the third Imam of Shi’ites. On Thursdays some governmental organizations and departments are open half day and are and Friday is holiday in Iran and therefore only few shops and trading centers are open on Fridays. During these two Lunar months daily activities somehow differ from other months and there are few religious holidays within these two months. Friday is official holiday.

The Iranian currency is called Rial but so often we hear the word "Toman" when shopping which is equivalent to 10 Rials.
