CET is 1 hour ahead of GMT all year, because both zones change their clocks on the same dates. GMT is London time, GMT at UTC+0 in winter and BST at UTC+1 in summer. CET is Central European Time, CET at UTC+1 in winter and CEST at UTC+2 in summer. Paste a Unix timestamp, an ISO 8601 string or a plain date such as June 1 2026 3:00 pm and the converter shows that moment in both zones, with UTC and Unix time alongside.

Common questions
- What is the time difference between GMT and CET?
- CET is 1 hour ahead of GMT all year, because both zones change their clocks on the same dates. The table on this page lists common GMT hours with their CET equivalents, and the converter gives the exact gap for any date you enter.
- What time is it in CET right now?
- The CET panel at the top of the page shows the current local time there, next to GMT, so you can compare at a glance. The gap is the same whatever the date, so the reading never needs adjusting.
- How do I convert a specific GMT time to CET?
- Type the GMT time into the box and the panel shows the same moment in CET. For example, 09:00 in GMT on 1 June 2026 is 10:00 the same day in CET. A time with no zone is read as GMT on this page; the selector under the box switches that to CET or to your own zone, and a Unix number or an ISO 8601 string with an offset is always read as written.
- Does the GMT to CET difference change with daylight saving time?
- Not in practice. Both zones change their clocks at the same moment, on 29 March and 25 October in 2026, so the gap holds at 1 hour all year.
