IST and EET on the World Map
The map below highlights the IST (India Standard Time) and EET (Eastern European Time) timezone regions across the globe.
IST – India Standard Time
UTC+05:30India Standard Time (IST) is the time zone for India and Sri Lanka, 5 hours and 30 minutes ahead of UTC.
- •India is 10 hours 30 minutes ahead of EST and 5 hours 30 minutes ahead of GMT.
- •India uses a single time zone despite spanning 30° of longitude.
- •IST is one of only a handful of time zones with a 30-minute offset.
- •IST is the most populous single time zone in the world with over 1.4 billion people.
- •The Bombay Stock Exchange (BSE) and National Stock Exchange (NSE) operate on IST.
EET – Eastern European Time
UTC+02:00Eastern European Time (EET) is used in Eastern Europe, the Middle East, and northeastern Africa, 2 hours ahead of UTC.
- •EET covers countries across three continents: Europe, Asia, and Africa.
- •Cairo is the most populous city in the EET zone.
- •Turkey used to be on EET but permanently moved to UTC+03:00 in 2016.
- •Finland, the Baltic states, and Greece all use EET.
Understanding the -3h 30m Gap: IST vs EET
IST runs on India Standard Time (IST) at UTC+05:30. EET runs on Eastern European Time (EET) at UTC+02:00. That puts IST 3 hours 30 minutes behind EET — a difference of -3h 30m at the current offsets.
In practice, when it is 9:00 AM in IST it is 5:30 AM in EET. Midnight in IST is 8:30 PM in EET. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert IST to EET time
- Scheduling a call from IST to EET: a 10:00 AM start in IST lands at 6:30 AM in EET, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both IST and EET are inside the 9-to-5 working day between 12:30 PM and 5:00 PM IST time (9:00 AM–1:30 PM EET). That is roughly 4 hours 30 minutes of usable overlap.
- Booking travel or deliveries: tracking EET local time against IST keeps pickup windows and arrival estimates honest across the -3h 30m offset.
- Always state the zone abbreviation, not just the hour. "3:00 PM IST" is unambiguous; "3 PM" across a -3h 30m gap is not.
- Block 12:30 PM–5:00 PM IST as the recurring meeting window if you work primarily from IST and need EET colleagues present.
About IST (India Standard Time)
India Standard Time (IST) is the time observed throughout India and Sri Lanka. It is based on the 82.5°E meridian, passing through Mirzapur in Uttar Pradesh. India uses a single time zone despite spanning roughly 30° of longitude, which has been debated. IST does not observe daylight saving time. India is the world's most populous country, making IST one of the most-used time zones globally. The IT outsourcing industry and call centers operate primarily on IST, making the EST-to-IST conversion one of the most searched timezone conversions.
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 IST and EET
Both IST and EET sit inside the 9 AM – 5 PM working day between 12:30 PM–5:00 PM IST, which is 9:00 AM–1:30 PM EET. That gives roughly 4 hours and 30 minutes of shared time — the safest window for a live call or meeting.
Business hours overlap
IST and EET overlap for about 4 hours during the working day — enough for meetings if you avoid the edges of the window.
IST is 3 hours 30 minutes behind EET (IST UTC+05:30 → EET UTC+02:00). The shared working window is 12:30 PM–5:00 PM IST. Remember to re-check around daylight-saving transitions.
