GMT to CET

The difference month by month — the same all year, even though both zones move their clocks — and what that means for a call between London and Berlin.

How far apart are GMT and CET?

CET is 1 hour ahead of GMT on every date the pinned table covers.

When it is 9:00 AM in London, it is 10:00 AM in Berlin.

How does the difference change month by month?

The difference is the same in every month of 2026, which is unusual for a zone pair and worth checking rather than assuming. Here it is, month by month.

Dates here are calendar dates in GMT time. Where a clock change happens overnight, the calendar in the other zone can already have turned over.

When does the usual difference not hold?

It always holds. Both zones move their clocks on the same dates, so the difference between them never breaks.
