Current time in Iran 30, Iran
The local time in Iran 30 is the same as elsewhere in Iran. The national time zone is three hours and thirty minutes ahead of Coordinated Universal Time. That half-hour difference is important when comparing the region with places that use whole-hour offsets.
Iran does not divide its provinces into separate time zones. A journey from this region to Tehran, Isfahan, Shiraz, or another Iranian city therefore requires no clock adjustment. Local schedules, transport departures, business hours, and appointments all use the same national time.
Time zone: Iran Standard Time UTC offset: UTC+3:30 Clock changes within Iran: none between provinces Useful comparison: add three hours and thirty minutes to UTC A half-hour offset is small enough to overlook and large enough to make an online meeting awkward.
Cities and local time
The name Iran 30 is an administrative label rather than the familiar name most residents would use in conversation. It commonly corresponds to Alborz Province, whose principal urban centre is Karaj. Other populated places in the province include Fardis, Nazarabad, Hashtgerd, and Eshtehard.
Every city and settlement in the region uses the same clock. Karaj is close to Tehran and is often the most practical reference point when arranging travel or checking local conditions. Fardis forms part of the heavily urbanised area nearby, while towns farther west retain the same time despite their different surroundings.
When a booking, address, or weather service displays “Iran 30,” check the accompanying city name. Administrative codes can be less intuitive than geographic names, but they do not indicate a separate time zone.
Sunrise across the region
Sunrise depends on the date and the exact coordinates used. Eastern parts of the province see the Sun appear slightly earlier than western parts on the same morning. Elevation, mountains, buildings, and the local horizon can also affect when direct sunlight becomes visible.
A sunrise time calculated for Karaj is suitable for Karaj but should not be treated as exact for every town in the region. Use the nearest listed city when planning photography, an early departure, outdoor work, or a religious observance.
Choose the correct city or coordinates. Confirm that the displayed time uses UTC+3:30. Check the intended calendar date. Allow for hills or buildings that may obscure the horizon.
Questions and answers

- Which city should I use for a general time check?
