Time Conversion Guide: EET to Tehran

EET runs on Eastern European Time (EET) at UTC+02:00. Tehran runs on Iran Standard Time (IRST) at UTC+03:30. That puts EET 1 hour 30 minutes ahead of Tehran — a difference of +1h 30m at the current offsets.

In practice, when it is 9:00 AM in EET it is 10:30 AM in Tehran. Midnight in EET is 1:30 AM in Tehran. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert EET to Tehran time

Scheduling a call from EET to Tehran: a 10:00 AM start in EET lands at 11:30 AM in Tehran, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both EET and Tehran are inside the 9-to-5 working day between 9:00 AM and 3:30 PM EET time (10:30 AM–5:00 PM IRST). That is roughly 6 hours 30 minutes of usable overlap.
Watching a live event or market open: EET viewers need 10:30 AM in Tehran to catch a 9:00 AM start there, and 10:30 PM if the event is anchored to EET.

Always state the zone abbreviation, not just the hour. "3:00 PM EET" is unambiguous; "3 PM" across a +1h 30m gap is not.
Block 9:00 AM–3:30 PM EET as the recurring meeting window if you work primarily from EET and need Tehran colleagues present.

About EET (Eastern European Time)

Eastern European Time (EET) covers a wide geographical area including Eastern Europe (Finland, Greece, Romania, Bulgaria, Ukraine), the Middle East (Israel, Lebanon, Jordan), and northeastern Africa (Egypt, Libya). During summer, most EET countries switch to Eastern European Summer Time (EEST, UTC+03:00). Turkey permanently moved to UTC+03:00 in 2016, effectively leaving EET.

About IRST (Iran Standard Time)

Iran Standard Time (IRST) is one of the few time zones with a 30-minute offset. Iran observes daylight saving time (IRDT, UTC+04:30) from late March to late September. Tehran, the capital, is one of the largest cities in the Middle East.

Best time to call between EET and Tehran

Both EET and Tehran sit inside the 9 AM – 5 PM working day between 9:00 AM–3:30 PM EET, which is 10:30 AM–5:00 PM IRST. That gives roughly 6 hours and 30 minutes of shared time — the safest window for a live call or meeting.

Business hours overlap

EET and Tehran share 6 hours of working-hours overlap (9:00 AM–3:30 PM EET), so scheduling a live meeting is straightforward.

EET is 1 hour 30 minutes ahead of Tehran (EET UTC+02:00 → IRST UTC+03:30). The shared working window is 9:00 AM–3:30 PM EET. Remember to re-check around daylight-saving transitions.
