About the time in Tehran
Clocks in Tehran stay put all year. There is no summer-time switch to remember, so UTC +3:30 is what you will get in January and in July alike — useful if you book recurring calls with people in Iran.
Tehran runs on Asia/Tehran, which puts the city UTC +3:30 from Coordinated Universal Time right now. The clock at the top of this page is not copied from your device: it is anchored to our reference timestamp and re-rendered every second against the IANA time zone database, so it stays right even when a laptop or phone has quietly drifted.
Sunrise today lands at 05:27 and sunset at 06:47 local time, giving 13h 20m of daylight. Those figures come from the city's own coordinates (35.69, 51.42) rather than a country-wide average, so they match what you would actually see from a window in Tehran.
