About Tehran time
Tehran keeps one clock.
Tehran offers many advantages for professionals and entrepreneurs. Its strategic location in Iran provides convenient access to both European and Asian markets. Business hours in Tehran center around the afternoon, with many offices opening mid-morning and winding down before sunset since there is no daylight saving time to contend with. If you're coordinating with teams further east or west, remember that Tehran's half-hour offset is its own quiet superpower — meetings tend to start late morning, leaving collaborative blocks across Eurasia neatly straddle Tehran's working day.
