Fixed and moving dates. Nowruz, Islamic Republic Day, Sizdah Bedar, 15 Khordad, Revolution Day and Oil Nationalisation Day sit on the solar calendar. They fall on the same Gregorian dates every year, give or take a day. The religious holidays follow the Islamic lunar calendar. They move about 11 days earlier each Gregorian year. The calendar office fixes them in advance, but the final call on Eid al-Fitr and some other dates rests on moon sighting.
The weekend. Friday is the weekly day off across Iran. Many offices and schools also close or work short hours on Thursday. Public holidays in Iran that land on a Friday are not moved to another day.
Nowruz. Only four of its days are public holidays in Iran, but the country slows for two weeks. Government offices, banks and many shops shut or open short hours until Sizdah Bedar on 13 Farvardin. Trains, buses and domestic flights sell out early. Hotels in Shiraz, Isfahan, Yazd and the Caspian coast fill up weeks ahead.
Muharram and Ramadan. Tasua and Ashura bring processions and street mourning, and most businesses close. Ramadan is not a holiday, but opening hours change and eating in public in daylight is not allowed. It starts about 11 days earlier each year.
Unplanned closures. The government often shuts schools and offices at short notice for air pollution, heat waves or power and gas shortages. These are announced a day or two ahead, usually by province, and do not count as public holidays in Iran. Banks and the Tehran Stock Exchange follow the official calendar.
Nowruz starts the day the March equinox passes before noon, Tehran time. If it passes after noon, 1 Farvardin is the following day.
