Tunisia marks the first day of Muharram, the beginning of the Islamic year, as a national public holiday each year.
|2020||20 Aug||Thu||Islamic New Year|
|2021||9 Aug||Mon||Islamic New Year|
Most Tunisians are Sunni Muslims, but both Sunnis and Shiites observe this holiday with fasting and prayer, though some other traditions differ on a sectarian basis.
The dating of the Islamic Calendar begins in C.E. 622 with the flight (Hijira) of Muhammad from Mecca to Medina.
The Islamic Calendar has only 354 or 355 days a year, being lunar-based. Therefore the date of Islamic New Year moves by 10 to 12 days on the Gregorian Calendar, which contains 365 days.
