About these dates
Dates come from the open-source python-holidays project (0.106, MIT licence), which follows each country’s laws and official calendars; Hourora built these tables from it on 16 October 2026. Names are shown as the source gives them, in the local language and in English, without machine translation.
Dates marked “estimated” follow lunar or religious calendars and can move by a day when they are announced. Days off decreed at short notice, such as bridge days, may be missing. Check with an official source before you book.
Long weekends count the weekend (Friday) and nationwide public holidays only. “When” counts days by the local date in Tehran.
