About time in Tehran

Tehran keeps Iran Standard Time, UTC+3:30 from UTC all year. The offset never changes, so any difference between you and Tehran moves only when your own clocks do.

Tehran shares the zone Asia/Tehran with Mashhad, Isfahan, Karaj, Tabriz, so a time here is also the time there. One canonical page per zone keeps the difference honest: the settlement name changes, the clock does not.

Offsets and daylight saving rules come from the IANA time zone database — see IANA time zone notes for what that data does and does not promise about future dates.
