🇮🇷 德黑兰

Tehran is the capital and most populous city of Iran, home to roughly 7.2 million residents. It sits in the Asia/Tehran time zone, which keeps a standard offset of UTC+3:30 — one of the world's few half-hour zones. Iran discontinued seasonal daylight saving time in 2022, so the offset now holds constant throughout the year, and local clocks run three and a half hours ahead of Coordinated Universal Time. Located in northern Iran near 35.7°N, 51.4°E, the city serves as the seat of national government and the country's administrative centre. Its population places it among the largest urban centres of Western Asia.
