Convert a specific time from AST to EET

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 AST and EET?

Eastern European Time is 6 hours ahead of Atlantic Time. To go from AST to EET you add 6 hours. That gap is not fixed.

This page recomputes it rather than assuming.

AST to EET conversion table

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

Does daylight saving change AST to EET?

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.

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.

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 AST ahead of or behind EET?

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

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