Understanding Iranian Standard Time (IRST)
Iranian Standard Time, often abbreviated as IRST, is the official time zone observed throughout the Islamic Republic of Iran. Unlike many countries that align with whole or half-hour UTC offsets, Iran maintains a unique offset of UTC+03:30. This means that Iran is precisely three and a half hours ahead of Coordinated Universal Time (UTC), which is the primary time standard by which the world regulates clocks and time. The IANA time zone identifier for Iran is Asia/Tehran, reflecting its geographical and cultural context within the Asian continent, with Tehran serving as the reference point for the national time standard.

This specific offset is not arbitrary. Iran bases its standard time specifically on the solar time at 52.5° east longitude. This meridian runs approximately 400 kilometers (250 miles) east of Tehran, providing a consistent astronomical basis for the nation's timekeeping. This same meridian is also fundamentally linked to the Persian Solar Hijri calendar, or Iranian calendar, which is the official calendar of Iran. It is used to set the precise start of the year, an event known as Nowruz (or Norooz), which typically falls around the vernal equinox. This deep connection to solar events underscores the historical and cultural significance of Iran's time zone, moving beyond mere technical specifications to embrace a profound link with astronomical phenomena and ancient traditions. Understanding this foundational aspect is key to grasping the nuances of what time in Iran truly represents.
Iran and Daylight Saving Time: A Recent Shift
One of the most significant changes concerning what time in Iran in recent years has been the abolition of Daylight Saving Time (DST). For many years, like numerous countries worldwide, Iran observed DST, advancing clocks by one hour during warmer months to make better use of daylight. However, this practice was officially discontinued. Iran has not had daylight saving time since 2022. This decision means that the country now maintains a consistent UTC+03:30 offset throughout the entire year, eliminating the biannual clock changes that were once a feature of Iranian life.
The cancellation of daylight saving time simplifies time calculations for both residents and international visitors or businesses. There are no longer "official time change dates" for winter time or daylight saving dates to track. This permanent adherence to Iranian Standard Time (IRST) streamlines scheduling and reduces potential confusion that often arises from seasonal clock adjustments. For instance, prior to 2022, one would need to consider whether it was standard time or DST when calculating time differences with other countries. Now, the calculation remains constant, providing greater predictability and ease of planning for anyone interacting with Iran, whether for travel, communication, or commerce.
Comparing Iran Time to Major Global Cities
When planning international calls, business meetings, or travel, understanding the time difference between Iran and other global hubs is essential. Given Iran's unique UTC+03:30 offset and its permanent non-observance of DST, these comparisons become straightforward once you grasp the fixed difference. This section will specifically detail the time difference with New York, a major global financial and cultural center, providing a clear example of how to calculate time disparities.
Iran vs. New York Time
New York City, located in the Eastern Time Zone (ET), observes both Eastern Standard Time (EST) and Eastern Daylight Time (EDT). This means its offset changes seasonally, which directly impacts its time difference with Iran. The provided data explicitly states the relationship:
- When New York is on Standard Time (EST, UTC-05:00), the time in Iran is 8 hours and 30 minutes ahead of the time in New York.
- When New York is on Daylight Saving Time (EDT, UTC-04:00), the time in Iran is 7 hours and 30 minutes ahead of the time in New York.
Let's illustrate this with an example. If it's 10:00 AM EST in New York (Standard Time), you would add 8 hours and 30 minutes to find the time in Iran, making it 6:30 PM in Tehran. Conversely, if it's 10:00 AM EDT in New York (Daylight Saving Time), you would add 7 hours and 30 minutes, resulting in 5:30 PM in Tehran. This consistent calculation, regardless of the time of year in Iran, simplifies international scheduling significantly. It's crucial for anyone needing to know what time in Iran it is relative to a major Western city.
Current Local Time Across Iranian Cities
One of the most common questions for anyone planning to visit or connect with Iran is, "What time is it right now?" The good news is that Iran operates on a single national time zone. This means that the current local time is the same across all of Iran's cities, from its bustling capital to its ancient cultural centers and industrial hubs. Whether you're interested in Tehran, Mashhad, Isfahan, Karaj, Tabriz, or Shiraz, the clock shows the identical time.
Tehran: The Capital City's Time
As the capital and largest city, Tehran serves as the de facto reference point for Iranian time. The current local time right now in Tehran, Iran, is consistently UTC+03:30. This page will give you the current local time in Tehran, Iran, along with the day of the week and date. For instance, if you see the time right now in Tehran, Iran is 22:40:36, it means it's 10:40 PM and 36 seconds in the capital. This consistency simplifies any inquiry about what time in Iran it might be at any given moment, as the answer for Tehran applies nationwide.
Time in Other Major Iranian Cities
While Tehran is the focal point, it's important to reiterate that cities like Isfahan, Karaj, Mashhad, Shiraz, and Tabriz all observe the exact same time. There are no internal time zone differences within Iran. This unified approach makes domestic travel and communication straightforward. For example, the time in Isfahan is also 8 hours and 30 minutes ahead of the time in New York when New York is on standard time, and 7 hours and 30 minutes ahead when New York is on daylight saving time, mirroring Tehran's relationship. This uniformity is a significant convenience for anyone navigating the country or coordinating activities across different regions.
The Solar Basis of Iranian Time
Iran's timekeeping is deeply rooted in astronomical observations, particularly the position of the sun. As mentioned, Iran bases its standard time specifically on the solar time at 52.5° east longitude. This meridian is not just a line on a map; it represents a significant astronomical reference point that dictates the rhythm of daily life and cultural events in Iran. This unique approach contrasts with many countries that simply adopt a time zone based on political or geographical convenience, often aligning with GMT/UTC in whole-hour increments.
The concept of "solar noon" is particularly relevant here. Solar noon is the moment when the sun reaches its highest point in the sky for a given location on a particular day. In Tehran, the local time is typically a few minutes ahead of solar noon. For example, the provided data indicates that the local time in Tehran is 3 minutes 10 seconds ahead of solar noon (middle of the solar day). This slight offset reflects the precise calculation based on the 52.5° east meridian, which is slightly east of Tehran itself. Furthermore, understanding solar events like sunrise and sunset is crucial for daily life, influencing prayer times and daily routines. The sunrises and sunsets in Tehran take approximately 2 minutes 57 seconds, indicating the duration of twilight. Today's maximum elevation angle the sun achieved (solar noon) was 75.92 degrees, i.e., 0.16 degrees higher than yesterday, showcasing the precision with which these solar movements are tracked and how they subtly influence the perceived timing of the day.
Practical Applications for Travelers and Businesses
For travelers planning a visit to Iran, or businesses engaging with Iranian counterparts, understanding the time nuances goes beyond mere curiosity. It impacts everything from flight schedules and meeting times to daily activities and communication strategies. Being aware of what time in Iran it is, and how it relates to your own location, can prevent misunderstandings and foster efficiency.
Checking Sunrise and Sunset in Iran
Beyond the current hour and minute, knowing the sunrise and sunset times is invaluable for various reasons. For tourists, it helps plan sightseeing activities, photography sessions, or simply knowing when to expect daylight. For religious observers, these times are critical for daily prayers (Salat). Information services often explore Tehran's sunrise and sunset, as well as moonrise and moonset, providing a comprehensive astronomical outlook for the city. This data is readily available online and can be crucial for daily planning, especially given the rapid changes in daylight hours depending on the season.
Using Time Zone Converters
While this article provides detailed explanations, the easiest way to compare Tehran with other cities around the world, or to convert time from Iran (Islamic Republic of) to any time zone, is to use a reliable online time zone converter. These tools instantly calculate the difference, taking into account DST rules (or lack thereof) in both locations. If you need to compare more than just two places at once, advanced converters can display multiple cities simultaneously, making complex international scheduling far simpler. This is particularly useful for global businesses operating across several time zones, ensuring everyone is on the same page regarding meeting times or deadlines.
Iran Time Zone Identifier and GMT/UTC Difference
For technical and professional purposes, understanding the official time zone identifier and its precise difference from GMT/UTC is paramount. Iran's time zone is officially recognized as UTC+03:30. This means it is 3 hours and 30 minutes ahead of Coordinated Universal Time (UTC). Historically, the difference from Greenwich Mean Time (GMT) was also a common
