Calendar


Iranian Official Calendar is Solar Hijri.

Iranian Official Calendar is Solar Hijri, based on Jalali calendar, the most accurate calendar. This Calendar is the result of an astronomers headed by Omar Khayam in 5th century AH.

A year in this calendar consists of 12 months(6 first months has 31 days, the next 5 months has 30 days and last month has 29 days). A complete turning of the earth around the sun takes approximately  365 days and 6 hours. This is why every 4 years the 12th month has 30 days and that year is called a leap year.

The Iranian year usually begins within a day of 21 March of the Gregorian calendar. To find the corresponding year of the Gregorian calendar, add 621 or 622 (depending on the time of the year) to a Solar Hejri year.
