EET and AST on the World Map
The map below highlights the EET (Eastern European Time) and AST (Atlantic Standard Time) timezone regions across the globe.
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.
AST – Atlantic Standard Time
UTC-04:00Atlantic Standard Time (AST) is the time zone for the Canadian Atlantic provinces and the Caribbean, 4 hours behind UTC.
- •Puerto Rico uses AST year-round and does not observe DST.
- •AST is 1 hour ahead of EST.
- •Halifax, the capital of Nova Scotia, is the largest city in AST Canada.
Understanding the -6h Gap: EET vs AST
EET runs on Eastern European Time (EET) at UTC+02:00. AST runs on Atlantic Standard Time (AST) at UTC-04:00. That puts EET 6 hours behind AST — a difference of -6h at the current offsets.
In practice, when it is 9:00 AM in EET it is 3:00 AM in AST. Midnight in EET is 6:00 PM in AST. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert EET to AST time
- Scheduling a call from EET to AST: a 10:00 AM start in EET lands at 4:00 AM in AST, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both EET and AST are inside the 9-to-5 working day between 3:00 PM and 5:00 PM EET time (9:00 AM–11:00 AM AST). That is roughly 2 hours of usable overlap.
- Booking travel or deliveries: tracking AST local time against EET keeps pickup windows and arrival estimates honest across the -6h offset.
- Always state the zone abbreviation, not just the hour. "3:00 PM EET" is unambiguous; "3 PM" across a -6h gap is not.
- Block 3:00 PM–5:00 PM EET as the recurring meeting window if you work primarily from EET and need AST 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 AST (Atlantic Standard Time)
Atlantic Standard Time (AST) covers Canada's Atlantic provinces (Nova Scotia, New Brunswick, Prince Edward Island, and most of Labrador), as well as several Caribbean nations. Puerto Rico and the US Virgin Islands use AST year-round without daylight saving time. The Canadian provinces switch to Atlantic Daylight Time (ADT) in summer.
Best time to call between EET and AST
Both EET and AST sit inside the 9 AM – 5 PM working day between 3:00 PM–5:00 PM EET, which is 9:00 AM–11:00 AM AST. That gives roughly 2 hours of shared time — the safest window for a live call or meeting.
Business hours overlap
EET and AST overlap for about 2 hours during the working day — enough for meetings if you avoid the edges of the window.
EET is 6 hours behind AST (EET UTC+02:00 → AST UTC-04:00). The shared working window is 3:00 PM–5:00 PM EET. Remember to re-check around daylight-saving transitions.
