When the clocks change in Tehran
Tehran does not change its clocks. The offset stays at UTC+03:30 every day of the year, so a time arranged here means the same thing in January as it does in July. That makes Tehran a straightforward place to schedule against — there is no window in the calendar where a recurring meeting quietly shifts by an hour.
Of the cities compared further down this page, New York, London and Sydney do change their clocks, so their difference from Tehran moves by an hour twice a year; Dubai, New Delhi, Singapore and Tokyo do not, so those differences never change.
Calling Tehran from another time zone
A working day of roughly 09:00 to 17:00 in Tehran corresponds to 05:30–13:30 UTC. To find the equivalent window where you are, add your own offset to those hours: somewhere on UTC+00:00 would be looking at 05:30–13:30.
Taking a working day as 09:00 to 17:00 in each place:
- New York has no overlap at all: when it is 09:00 there, it is already 16:30 in Tehran, so a call means an early start or a late finish for someone.
- London’s working day overlaps with Tehran’s for 5½ hours, from 11:30 to 17:00 Tehran time.
- Tokyo overlaps for only 2½ hours, from 09:00 to 11:30 Tehran time — late in the day at one end and early at the other.
These windows use the offsets in force on 2026-10-09; where one side observes daylight saving and the other does not, they move by an hour twice a year.
