Time in Daily Life
Iran uses UTC+3:30 year-round with no daylight saving since 2022, a half-hour offset shared by Tehran, Isfahan, and Shiraz.
The country previously observed a summer shift but abandoned it, so schedules now stay fixed, and the half-hour difference is a small but constant factor when calling neighbours like Turkey or Pakistan.
During Nowruz, the Persian New Year in March, daily routines loosen and family visits stretch late into the night across the country.
The Persian New Year in March opens two weeks of family visits and travel, and the long summer heat sends Tehran's middle class toward the cooler Caspian coast and mountain resorts.
Domestic flights connect Tehran to Mashhad and Shiraz within a few hours, and the single national offset means no clock change when boarding, even though the country spans wide.
