Convert a specific time from EET to AST

Pick any time and date to convert it both ways. The conversion runs in your browser against the real zone rules, so a date inside a daylight saving period gets that period's offset rather than today's.

What is the time difference between EET and AST?

Atlantic Time is 6 hours behind Eastern European Time. To go from EET to AST you subtract 6 hours. That gap is not fixed. Across 2026 the distance between these two zones takes 2 different values, from 5 hours to 6 hours, because the two sides change their clocks on different dates. This page recomputes it rather than assuming.

EET to AST conversion table

Every hour of Friday, September 25, 2026 in Eastern European, with the matching reading in Atlantic. 6 of the 24 hours land on a different calendar date in Atlantic, which is the part people get wrong when they schedule across this pair.

What are the best hours to schedule a call between EET and AST?

2 hours of the standard 9:00 am to 5:00 pm working day line up in both zones, from 3:00 pm EET to 5:00 pm EET. In Atlantic that window reads 9:00 am to 11:00 am. Outside it, one side is either not yet at their desk or already gone.

Does daylight saving change EET to AST?

Eastern European Time is currently on EEST and changes next on Sunday, October 25, 2026, when the clock falls back from 3:59 am to 3:00 am and the offset moves from UTC+3 to UTC+2.

Atlantic Time is currently on ADT and changes next on Sunday, November 1, 2026, when the clock falls back from 1:59 am to 1:00 am and the offset moves from UTC-3 to UTC-4.

Because the two sides do not move together, the answer to this conversion changes during the year. The United States changes on the second Sunday in March and the first Sunday in November, while the United Kingdom and European Union change on the last Sunday in March and the last Sunday in October. Those dates are weeks apart, which opens a window each spring and autumn where the usual gap is an hour out. The table above is built for today, not for an average day.

Is EET ahead of or behind AST?

EET is ahead of AST by 6 hours: when it is 12:00 pm in Eastern European, it is 6:00 am in Atlantic. One wrinkle worth knowing: EET and EEST are two names for the same zone, not two zones. Eastern European Time reads EET in winter and EEST in summer. When somebody types "eet to ast" they nearly always mean the zone rather than the literal winter offset, so this page resolves EET to Europe/Athens and AST to America/Halifax and applies whichever offset is genuinely in force on the day.

Eastern European Time covers Athens, Helsinki, Bucharest and Kyiv. Atlantic Time covers Halifax, Moncton and the Canadian Maritimes. The identifiers behind them are Europe/Athens and America/Halifax, which is what any calendar or scheduling system should be storing rather than a fixed number of hours.
