CET to London

About Central European Time

Central European Time covers most of the continent, from Spain to Poland, at UTC+1 as CET and UTC+2 as CEST. Every EU country changes at the same instant — 01:00 UTC on the last Sunday of March and of October — rather than at 02:00 local like North America, so the whole bloc moves together and the steps between European zones never wobble.

Cities on this clock: Paris, Berlin, Madrid, Rome, Amsterdam, Brussels, Vienna, Warsaw.

About United Kingdom Time

The United Kingdom is on GMT (UTC+0) for about five months and BST (UTC+1) for the rest, changing on the last Sunday in March and the last Sunday in October. Ireland keeps exactly the same clock, so every figure here applies to Dublin as well as London.

Cities on this clock: London, Lisbon, Dublin, Edinburgh, Manchester.

How the difference is worked out

Neither Central European Time nor United Kingdom Time moves its clock relative to the other, so united kingdom time is 1 hour behind central european time is a rule rather than a fact about one particular year. The hour-by-hour table above holds on every date. The one exception is a few hours on each transition day: the two zones do change their clocks, and not at the same instant, so the gap is briefly an hour off between one switching and the other.

With both zones on their own standard time — daylight saving not in force anywhere — United Kingdom Time is 1 hour behind Central European Time. That figure never changes; everything else on this page follows from it plus whichever clocks have moved.

Every figure here comes from the IANA time zone database via your browser's own Intl engine, using the zone ids Europe/Paris and Europe/London. Nothing is looked up on a server and nothing about your visit is recorded.
