Add comparison cities with the “+ Add City” button: Click + Add City and search for cities such as London, Dubai, and New York to compare Tehran with major finance, trade, and diaspora hubs. This is especially practical for import-export coordination, energy-sector communication, or scheduling calls between Iran and teams in Europe, the Gulf, or North America.
Use the visual grid to select a meeting window: Click Select to enter selection mode, then drag across Tehran’s row from 9:00 AM to 11:00 AM to highlight that time block in purple. On a standard-offset day, that shows 5:30 AM to 7:30 AM in London, 12:30 AM to 2:30 AM in New York, and 8:30 AM to 10:30 AM in Dubai, which quickly confirms whether a Tehran morning meeting works for your other participants.
Export or share the selected time range: After selecting the range, use the export options for ICS download, Google Calendar, Gmail, Copy to clipboard, or Share link. This is helpful when sending a confirmed Tehran meeting slot to a distributed team, because each person sees the event translated into their own local time automatically.
About Tehran Time Zone
Tehran uses the IANA time zone Asia/Tehran, which is the standard identifier used in operating systems, calendar apps, server logs, and scheduling platforms. The city’s standard UTC offset is UTC+03:30, placing it 3 hours and 30 minutes ahead of Coordinated Universal Time. That half-hour offset makes Tehran different from many nearby capitals that use whole-hour offsets, so it is important to verify exact local time before booking calls or flights.
At present, Iran does not observe daylight saving time, so Tehran remains on UTC+03:30 year-round. Iran ended seasonal clock changes after legislation took effect in 2022, meaning there are no spring-forward or fall-back transitions to account for in current scheduling. For businesses and remote teams, this creates more predictable recurring meeting times than in countries that still shift clocks seasonally.
Tehran is the capital of Iran and the country’s primary political, financial, and administrative center, located in north-central Iran near the Alborz mountain range. Compared with neighboring time zones, Tehran is 30 minutes ahead of Dubai (UTC+04:00 vs Tehran’s UTC+03:30 means Dubai is actually 30 minutes ahead)? Wait carefully: Dubai is UTC+04:00, so Dubai is 30 minutes ahead of Tehran. Tehran is 30 minutes behind Gulf cities such as Dubai and Abu Dhabi, 1 hour behind Baku (UTC+04:00), and 30 minutes ahead of Baghdad and Riyadh (UTC+03:00). These small but important differences matter for aviation schedules, regional trade calls, and cross-border logistics.
Tehran City Details
Tehran is the largest city in Iran, with a population of 7,153,309, making it the country’s main center for government, higher education, media, finance, and industry. Its large urban population supports dense business activity, so accurate time coordination is essential for meetings with local offices, suppliers, universities, and public institutions.
The city is located at 35.69439° N, 51.42151° E, placing it on the southern slopes of the Alborz range and within easy reference of major domestic and international transport corridors. For travelers and logistics planners, these coordinates identify Tehran’s position in northern Iran, east of the central Middle East trade routes connecting the Gulf, the Caucasus, and South Asia.
Tehran uses the Iranian rial (IRR) as its official currency, and Iran’s country dialing code is +98. If you are arranging payments, invoicing local vendors, or placing international calls to Tehran, these details are as important as the time zone because they affect banking timing, customer support hours, and communication formats.
Time Differences from Tehran
Tehran is 3 hours 30 minutes ahead of UTC, and because it currently stays on the same offset all year, its relationship to other cities changes mainly when those other cities enter or leave daylight saving time. This is especially relevant when coordinating with North America, Europe, and Australia, where seasonal clock changes can shift the overlap window by one hour.
Compared with major global cities:
- New York: Tehran is usually 7 hours 30 minutes ahead when New York is on Eastern Daylight Time, and 8 hours 30 minutes ahead when New York is on Eastern Standard Time.
- When it is 9:00 AM in Tehran, it is 1:30 AM in New York during EDT, or 12:30 AM in New York during EST.
- London: Tehran is usually 2 hours 30 minutes ahead when the UK is on British Summer Time, and 3 hours 30 minutes ahead when London is on Greenwich Mean Time.
- When it is 9:00 AM in Tehran, it is 6:30 AM in London during BST, or 5:30 AM in London during GMT.
- Tokyo: Tehran is 5 hours 30 minutes behind Tokyo year-round because Tokyo uses JST (UTC+09:00) and does not observe DST.
- When it is 9:00 AM in Tehran, it is 2:30 PM in Tokyo.
- Sydney: Tehran is 6 hours 30 minutes behind Sydney when Sydney is on Australian Eastern Standard Time (UTC+10:00), and 7 hours 30 minutes behind when Sydney is on Australian Eastern Daylight Time (UTC+11:00).
- When it is 9:00 AM in Tehran, it is 3:30 PM in Sydney during AEST, or 4:30 PM in Sydney during AEDT.
- Dubai: Tehran is 30 minutes behind Dubai year-round because Dubai uses Gulf Standard Time (UTC+04:00) with no DST.
- When it is 9:00 AM in Tehran, it is 9:30 AM in Dubai.
For practical scheduling, Tehran’s best overlap with London is often late morning to early afternoon in Iran, while overlap with New York usually falls in Tehran’s late afternoon or evening. If you work with Tokyo or Dubai, the overlap is much easier because the offset is smaller and both regions avoid seasonal clock changes.
Frequently Asked Questions
What time zone is Tehran in?
Tehran is in the Asia/Tehran time zone, which is the official IANA time zone identifier used by most digital systems and calendars. Its standard offset is UTC+03:30, so Tehran is 3 hours and 30 minutes ahead of UTC throughout the year under current rules.
Does Tehran observe daylight saving time?
No, Tehran does not currently observe daylight saving time. Iran ended seasonal clock changes in 2022, so clocks in Tehran now remain on UTC+03:30 year-round, which makes recurring meetings easier to manage than in regions that still switch between summer and winter time.
What is the time difference between Tehran and New York?
The time difference depends on whether New York is on daylight saving time. Tehran is typically 7 hours 30 minutes ahead of New York during U.S. daylight saving time and 8 hours 30 minutes ahead during standard time, so a morning in Tehran often corresponds to very late night or just after midnight in New York.
What is the best time to call Tehran from the US or UK?
From the UK, the most practical time is usually 8:00 AM to 11:00 AM London time, which corresponds to roughly 10:30 AM to 2:30 PM in Tehran during GMT, or one hour later relationship during BST. From the US East Coast, calling 8:00 AM to 10:00 AM New York time often reaches Tehran in the late afternoon or early evening, which is generally better than trying to match Tehran’s morning business hours from America.
What is the UTC offset for Tehran?
Tehran’s current UTC offset is UTC+03:30. This half-hour offset is less common than full-hour time zones, so it is worth checking carefully when creating calendar invites, especially for aviation, multinational operations, or remote teams using automated scheduling tools.
What currency does Tehran use?
Tehran uses the Iranian rial (IRR), which is the official currency of Iran. If you are planning travel, paying local service providers, or reviewing invoices from Tehran-based businesses, you should expect prices and transactions to be quoted in IRR, even though informal pricing discussions may sometimes reference toman equivalents locally.
How far ahead is Tehran compared with London?
Tehran is 3 hours 30 minutes ahead of London when London is on GMT, and 2 hours 30 minutes ahead when London is on BST. That means a standard 9:00 AM business start in Tehran corresponds to 5:30 AM in London during winter or 6:30 AM in London during summer, so midday Tehran is often the first practical overlap for live calls.
Is Tehran the same time as Dubai?
No, Tehran and Dubai are not on the same time. Dubai is 30 minutes ahead of Tehran because Dubai uses UTC+04:00 while Tehran uses UTC+03:30, so when it is 2:00 PM in Tehran, it is 2:30 PM in Dubai.
