The Iranian Calendar
The Iranian calendar has been based since pre-Islamic era on the movement of the sun . but the Islamic calendar which revolves round the movement of the moon is also current in Iran for religious purposes.
The Iranian solas calendar was modified in the 12th century AD by Omar Khayyam, the poet, scientist and astronomer.
The new calendar was named the Jalali calendar. It’s accuracy is one dap in 5000 years.
The Iranian calendar begins with the Hejira (departure), the day the ]Holy Prophet Mohammad left Mecca for Medina, in 421 AD. Each Iranian yearbegins on March 21st (the first day of spring) and ends on March 20th. The Iranian year is just over 365 days long and every four years, is a leap year, the last month of which, is considered as having 30 days instead of 29 days.
The Islamic calendar year, however, is about 354 days. Therefore, the two calendars, the national calendar and the religious calendar, do not coincide and vary from year to year.
The Iranian new year, the first day of spring, has since ancient times been a day of celebration, feast and joy.
