Public holidays in Iran
Iran uses three official calendar systems, including the Solar Hijri calendar as the main and national calendar, the Gregorian calendar for international events and Christian holidays, and the Lunar Hijri calendar for Islamic holidays. In 2008, the Iranian government's English-language newspaper Iran Daily wrote that "[the] problem of too many annual public holidays has perpetually been a subject of concern," pointing out that the government would often declare "unofficial holidays [...] to allow extended weekends" around the national holidays.
