Understanding the -1h 30m Gap: Iran vs EET
Iran runs on Iran Standard Time (IRST) at UTC+03:30. EET runs on Eastern European Time (EET) at UTC+02:00. That puts Iran 1 hour 30 minutes behind EET — a difference of -1h 30m at the current offsets.
In practice, when it is 9:00 AM in Iran it is 7:30 AM in EET. Midnight in Iran is 10:30 PM in EET. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert Iran to EET time
- Scheduling a call from Iran to EET: a 10:00 AM start in Iran lands at 8:30 AM in EET, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both Iran and EET are inside the 9-to-5 working day between 10:30 AM and 5:00 PM IRST time (9:00 AM–3:30 PM EET). That is roughly 6 hours 30 minutes of usable overlap.
- Booking travel or deliveries: tracking EET local time against Iran keeps pickup windows and arrival estimates honest across the -1h 30m offset.
- Always state the zone abbreviation, not just the hour. "3:00 PM IRST" is unambiguous; "3 PM" across a -1h 30m gap is not.
- Block 10:30 AM–5:00 PM IRST as the recurring meeting window if you work primarily from Iran and need EET colleagues present.
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.
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.
Best time to call between Iran and EET
Both Iran and EET sit inside the 9 AM – 5 PM working day between 10:30 AM–5:00 PM IRST, which is 9:00 AM–3:30 PM EET. That gives roughly 6 hours and 30 minutes of shared time — the safest window for a live call or meeting.
Business hours overlap
Iran and EET share 6 hours of working-hours overlap (10:30 AM–5:00 PM IRST), so scheduling a live meeting is straightforward.
Iran is 1 hour 30 minutes behind EET (IRST UTC+03:30 → EET UTC+02:00). The shared working window is 10:30 AM–5:00 PM IRST. Remember to re-check around daylight-saving transitions.
