What time is it in Iran?

Iran stays on UTC+3:30 all year. Its offset from UTC never moves, so its relationship to places that do change shifts twice a year instead — which is usually why someone checks. Right now it is 3 hours 30 minutes ahead of UTC, and 8 hours 30 minutes ahead of New York.

Tehran is 8 hours 30 minutes ahead of New York and 11 hours 30 minutes ahead of Los Angeles. 9am in New York is 5:30 pm in Tehran.

To convert a specific time rather than read the current one, the converter shows both directions with the next clock change for each.

The day is 10 hours 21 minutes long in Tehran, and losing 2 minutes a day. The sun peaks at 11:48 am, 12 minutes before noon on the clock. A UTC offset is a promise that the sun is overhead at midday on one meridian, and Tehran sits 4 minutes of solar time west of UTC+3:30’s. The rest is the equation of time, which swings about a quarter of an hour either way across the year.

The solar year swings 4 hours 50 minutes in Tehran: 14 hours 34 minutes of daylight at the June solstice against 9 hours 44 minutes at the December one. Being north of the equator, its longest day falls in June — the opposite way round from the other hemisphere.

Iran has kept UTC+3:30 since Wednesday, September 21, 2022, when it moved from UTC+4:30. Before that its clocks read 1 hour ahead of what they read now.
