What is Iran Standard Time (IRST)?
Iran Standard Time (IRST) is the official time zone used throughout the Islamic Republic of Iran. IRST is 3 hours and 30 minutes ahead of Coordinated Universal Time (UTC+03:30). Because Iran operates on a single time zone, the time remains consistent whether you are in Tehran, Mashhad, Isfahan, or Shiraz.
As of September 2022, Iran officially abolished the observance of Daylight Saving Time (DST). Therefore, the country remains on standard time (UTC+03:30) all year round, and there are no seasonal clock changes to worry about.
