About time in Tehran
Tehran runs on Iran Standard Time, abbreviated IRST, set at an unusual UTC+3:30 offset that includes an extra half hour. This thirty-minute offset places Tehran between the common whole-hour zones of its neighbors, a feature that often surprises travelers. For many years Iran shifted its clocks for daylight saving, but the country abolished the practice in 2022, so the offset now stays fixed all year. As a result, Tehran no longer springs forward or falls back, and IRST remains constant from January through December.
Tehran does not observe daylight saving time, so it keeps a fixed offset of UTC+3:30 (no DST) every day of the year. The live clock above reads Tehran's local time directly from the IANA time zone database in your browser, so it stays accurate through daylight-saving transitions without any manual adjustment.
