Tehran does not observe daylight saving time — it stays at UTC+3:30 all year round.
Tehran is 7h 30min ahead of New York and does not observe daylight saving time, so this difference stays constant all year round — unlike London, which changes clocks twice a year. Tehran uses a 30-minute offset (UTC+3:30) instead of a whole hour — like a handful of countries, including India and Nepal, that split the difference between whole-hour zones. Despite its geography, Iran keeps a single time zone nationwide, so every city we track there shares Tehran's offset.
