No clock changes: Iran stays on UTC+3:30 all year.
Time zone in Iran
Iran uses a single time zone: UTC+3:30 all year. Every clock in the country shows the same time.
Its offset, UTC+3:30, is not a whole number of hours, so the minutes differ too when you compare Iran with most of the world. No other zone in the database uses UTC+3:30.
Tehran lies at 51.4° east, where mean solar time is UTC+3:26 (four minutes per degree of longitude). That is within 4 min of its clock time, so the sun is highest close to noon.
Daylight saving time in Iran
No. Iran does not change its clocks under the current rules. It last used daylight saving time in 2022, after 34 years with summer time since 1970.
Clock history of Iran
The record begins with local mean time (clocks set by the sun, UTC+3:26 in Tehran), which ended on January 1, 1916, when TMT (UTC+3:26) replaced it. Between 1970 and 2024, a daylight saving period began in 34 of the 55 years, most recently in 2022. The first summer time in the record dates from 1977. The table summarises the clocks of Iran year by year since 1970, from the tzdata entry Asia/Tehran.
