CET to GMT converter
GMT is 2 hours behind CET for most of the year. The gap is different for part of the year, because only one side changes its clocks: in 2026 that is 1 January to 28 March (1 hour) and 25 October to 31 December (1 hour). If you schedule something in that period, check the date.

How to convert CET to GMT
To convert CET to GMT by hand, subtract 2 hours for most of the year, then fix the date if you cross midnight.
- 8 PM CET on 15 January is 7:00 PM GMT.
- 8 PM CEST on 15 July is 6:00 PM GMT.
- On the other side of the year, 8 PM CET on 13 February is 7:00 PM GMT, because the gap is then 1 hour.
- 8 PM CEST on 15 October is 6:00 PM GMT.
UTC is the easy anchor: convert to UTC first, then to the other zone, and you never have to think about which side changed its clocks.
About the two time zones
Central European Time (CET/CEST). Used in: Paris, Berlin, Madrid, Rome, Amsterdam, Brussels, Vienna, Stockholm, Oslo, Warsaw. Clocks go forward on the last Sunday in March and back on the last Sunday in October.
CET is the winter name and CEST (Central European Summer Time) is the summer name. People often write CET all year; the clock in Europe is on CEST from March to October.
Greenwich Mean Time (GMT). Used in: Reykjavik and much of West Africa use GMT all year. No daylight saving: the offset is the same all year.
GMT and UTC show the same time. The UK is on GMT only in winter; in summer it moves to BST, which is one hour ahead. This page uses the fixed GMT (UTC+0) zone.
