When the difference changes

Central European Time and Greenwich Mean 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 28, 2027Greenwich Mean Time is 1 hour behind
  2. March 28, 2027 – October 31, 2027Greenwich Mean Time is 2 hours behind
  3. October 31, 2027 – onwardsGreenwich Mean Time is 1 hour behind

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.

Daylight saving

Central European Time

Sunday, March 28, 2027

Clocks go forward one hour — 2:00 am becomes 3:00 am local time, and the zone is on CEST after that.

Greenwich Mean Time

No clock changes

Greenwich Mean Time stays on GMT all year, so its offset from UTC never moves.

Scheduling between the two

Working hours overlap from 10:00 am to 6:00 pm CET, which is 9:00 am to 5:00 pm GMT. Anything inside that window falls in the normal working day at both ends.

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

Greenwich Mean Time (GMT) is used in as a fixed UTC+0 offset. Note that the UK itself leaves GMT every summer — see British Time below.
