What is the current time in Iran?

The current time in Iran follows Iran Standard Time (IRST), set at UTC+3:30. As of May 21, 2026, the live clock reads 09:02:47 IRST, Thursday, according to time.is. This represents the official, year-round standard time for the entire country, from Tehran in the north to the Persian Gulf coast in the south.

Iran’s half-hour offset makes it distinctive. While most countries use whole-hour differences from UTC, Iran sits 3 hours and 30 minutes ahead — a choice rooted in the country’s geographic position and maintained since 1946, according to historical references on Living in Tehran. The offset aligns with the 52.5° E longitude that runs through Tehran, which falls roughly midway between the UTC+3 and UTC+4 whole-hour bands.

Tehran time and the national clock

Tehran serves as the canonical reference city for Iran’s time zone. World Time Buddy notes that the capital’s local clock is identical to the standard applied across all provinces and cities — there is no regional variation within Iran. Whether you are checking time in Isfahan, Shiraz, or Mashhad, the displayed time matches Tehran’s clock exactly.

No daylight saving adjustments in 2026

As confirmed by 24timezones.com, Tehran’s world-clock page for 2026 lists no upcoming daylight saving time changes. Iran formally ended DST practice after parliamentary approval in September 2022, with the final transition back to standard time occurring on September 21, 2022. Reuters reported that the legislation made permanent standard time the national practice, removing the twice-yearly clock shifts that had been in effect under the former Iran Daylight Time (IRDT) system.

What this means: Iran’s time has been stable since late 2022 with no seasonal adjustments — a simplification for anyone coordinating across time zones with Iranian counterparts.

How to convert time to Iran time?

Converting your local time to Iran time requires adding 3 hours and 30 minutes to Coordinated Universal Time (UTC). The formula is straightforward: Iran Time = UTC + 3:30. For example, if it is 05:30 UTC, the equivalent Iran time is 09:00 IRST.

Using online converter tools

Practical converter sites like Savvy Time and World Time Buddy allow you to select your city and instantly see the corresponding Iran time. These tools handle the half-hour offset automatically, removing the need for manual calculation. Simply enter your current location, and the converter displays the time in Tehran alongside your local clock.

Converting major world cities to Iran time

For quick reference, here is how Iran’s UTC+3:30 compares with major time zones around the world. When it is noon in New York (Eastern Time, UTC-4 during standard time), it is 20:30 in Iran on the same day. When it is 09:00 in London (UTC+0), Iran shows 12:30 the same day. When it is 14:30 in Dubai (UTC+4), Iran sits at 13:00 — one hour behind.

Travel guides such as Young Pioneer Tours recommend adding Tehran to a world clock app on your phone so the offset is always visible alongside your home time. For those tracking two time zones simultaneously, a dual-time watch or a phone world clock widget can reduce the need for repeated manual conversion.

Iran time vs. neighboring countries

Two neighboring nations share borders with Iran and maintain different offsets. Iraq operates at UTC+3:00, placing it 30 minutes behind Iran. Afghanistan is at UTC+4:30, making it one full hour ahead of Iran. These differences matter for cross-border coordination — for example, a 10:00 business call in Tehran arrives at 09:30 in Baghdad but 11:00 in Kabul on the same day.

The implication: The half-hour offset between Iran and Iraq is a common source of confusion in regional coordination; always confirm the specific time zone when scheduling cross-border calls or travel.

What is today’s date in Iran?

Iran uses two calendar systems in parallel. The Gregorian calendar, aligned with international standards, runs alongside the Solar Hijri (Persian) calendar, which begins each year around the spring equinox. Official government documents, newspapers, and daily public life often reference both — so today’s Gregorian date and the Persian calendar date are both valid references.

Tools like time.ir display both calendar dates simultaneously, making it easy to confirm the current Persian calendar day, month, and year alongside the standard Gregorian equivalent. This dual-system approach is standard practice in Iranian media, education, and commerce, so foreign visitors and remote workers should become familiar with the Persian calendar format to avoid date confusion.

Checking Iran’s date online

The quickest way to see today’s date in both calendar formats is to visit timeanddate.com or time.ir and search for Tehran. These sites display the current local time, the day of the week, and both Gregorian and Persian calendar dates side by side. For a quick mobile check, searching “Tehran time” in a web browser or using a world clock widget on your phone provides the same information without installing additional apps.

The pattern: Because Iran maintains two parallel calendar systems, always clarify which calendar is being used when receiving a date from an Iranian source — especially for scheduling, contracts, or travel arrangements.
