What is AST in EET?

Eastern European Time is 6 hours ahead

Atlantic Time is on UTC−3:00 and Eastern European Time is on UTC+3:00 right now. Both are on daylight saving, so their clocks read ADT and EEST. The gap changes during the year — see below.

When the difference changes

Atlantic Time and Eastern European Time do not change their clocks on the same dates, so the gap between them is not the same all year. Most converters show only today’s figure. These are the periods ahead:

  1. Now – October 24, 2026Eastern European Time is 6 hours ahead
  2. October 24, 2026 – November 1, 2026Eastern European Time is 5 hours ahead
  3. November 1, 2026 – March 14, 2027Eastern European Time is 6 hours ahead
  4. March 14, 2027 – March 27, 2027Eastern European Time is 5 hours ahead
  5. March 27, 2027 – onwardsEastern European Time is 6 hours ahead

Periods shorter than a day are not listed. Each zone changes at its own local time, so on a date when both move there are a few hours when the gap is briefly something else.

Scheduling between the two

Working hours overlap from 9:00 am to 12:00 pm ADT, which is 3:00 pm to 6:00 pm EEST. Anything inside that window falls in the normal working day at both ends.

A note on AST: it can also mean Arabia Standard Time (UTC+3). This page means Atlantic Time.

Atlantic Time (ADT) is used in Nova Scotia, New Brunswick and Puerto Rico

Eastern European Time (EEST) is used in Helsinki, Bucharest, Kyiv and Cairo
