EEST and IST on the World Map
The map below highlights the EEST (Eastern European Time) and IST (Greenwich Mean Time) timezone regions across the globe.

- •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.

- •GMT is based on the Prime Meridian (0° longitude) passing through Greenwich, London.
- •The Royal Observatory in Greenwich has been the reference point for GMT since 1884.

Understanding the -2h Gap: Bucharest vs Ireland
Bucharest runs on Eastern European Summer Time (EEST) at UTC+03:00, currently observing daylight saving time. Ireland runs on Irish Standard Time (IST) at UTC+01:00, also currently on daylight saving time. That puts Bucharest 2 hours behind Ireland — a difference of -2h at the current offsets.
In practice, when it is 9:00 AM in Bucharest it is 7:00 AM in Ireland. Midnight in Bucharest is 10:00 PM in Ireland. Because both zones shift for daylight saving, the gap between them only changes during the few weeks each year when their transition dates differ.

Why people convert Bucharest to Ireland time
- Scheduling a call from Bucharest to Ireland: a 10:00 AM start in Bucharest lands at 8:00 AM in Ireland, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both Bucharest and Ireland are inside the 9-to-5 working day between 11:00 AM and 5:00 PM EEST time (9:00 AM–3:00 PM IST). That is roughly 6 hours of usable overlap.
- Keeping family and friends in sync: knowing that 8:00 PM in Bucharest is 6:00 PM in Ireland makes it easy to avoid calling at 3 AM.
- Always state the zone abbreviation, not just the hour. "3:00 PM EEST" is unambiguous; "3 PM" across a -2h gap is not.
- Block 11:00 AM–5:00 PM EEST as the recurring meeting window if you work primarily from Bucharest and need Ireland colleagues present.
- Bucharest: Clocks fall back on Sun, Oct 25, 2026. Re-check this page after that date because the offset changes and so does the -2h gap.
- Ireland: Clocks fall back on Sun, Oct 25, 2026. Any meeting series spanning that date will shift by an hour in local time.
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 GMT (Greenwich Mean Time)
Greenwich Mean Time (GMT) is the clock time at the Royal Observatory in Greenwich, London, which sits on the Prime Meridian (0° longitude). GMT serves as the reference point from which all other time zones are calculated. The United Kingdom uses GMT during winter months and switches to British Summer Time (BST, UTC+01:00) from late March to late October. Several West African nations use GMT year-round. GMT is often used interchangeably with UTC (Coordinated Universal Time), although technically they are different – UTC is based on atomic clocks while GMT is based on Earth's rotation.
