When the difference changes

Atlantic Time and Central 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 – March 14, 2027Central European Time is 5 hours ahead
  2. March 14, 2027 – March 27, 2027Central European Time is 4 hours ahead
  3. March 27, 2027 – October 30, 2027Central European Time is 5 hours ahead
  4. October 30, 2027 – November 7, 2027Central European Time is 4 hours ahead
  5. November 7, 2027 – onwardsCentral European Time is 5 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 1:00 pm AST, which is 2:00 pm to 6:00 pm CET. 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 (AST) is used in Nova Scotia, New Brunswick and Puerto Rico

Central European Time (CET) is used in Berlin, Madrid, Rome, Amsterdam, Warsaw and Stockholm
