Capital status
National capital of Iran
Tehran is the capital and largest city of Iran, the political, economic, and cultural heart of the country with roughly 9 million residents in the city proper and over 16 million across its metropolitan area. The city runs on Iran Standard Time (IRST, UTC+3:30) and is the only place in the world where a 30-minute half-hour offset serves a national capital of this scale. Iran abolished daylight saving time on 21 September 2022, so Tehran no longer changes its clocks and stays at UTC+3:30 year-round. Sprawled along the southern slopes of the Alborz mountains at elevations ranging from about 900 to 1,800 metres, Tehran has been Iran's capital since the Qajar dynasty established it in 1786. It concentrates the bulk of the nation's universities, government ministries, and the Tehran Stock Exchange.
