About converting CET to GMT

Central European Time (Paris) and Greenwich Mean Time (Greenwich) are in different time zones, so a meeting, call or stream that's convenient in one may be early or late in the other. The clocks above update live and account for daylight saving automatically, so the time difference you see is the real one for today — not a fixed number that goes stale twice a year.

To plan across the two, type a time into the CET box (or tap a quick preset) and read the GMT equivalent, including a "next day" or "previous day" note when the conversion crosses midnight. For any other pair of zones or cities, use the full timezone converter.

CET vs GMT: the time difference through the year

The gap between CET and GMT changes during the year because only one of them uses daylight saving.

Best time to meet

The two zones

CET · Central European Time

Central European Time is UTC+1 in winter (CET) and UTC+2 in summer (CEST). It covers Paris, Berlin, Madrid, Rome, Amsterdam and most of the EU, switching on the last Sundays of March and October.

GMT · Greenwich Mean Time

Greenwich Mean Time is UTC+0 all year. It is the base for world time; the UK uses GMT only in winter and switches to BST in summer.

Frequently asked questions

6 answers
What is the time difference between CET and GMT?
It's shown live at the top of this page (and it can change with daylight saving). The converter uses the current, DST-aware difference between Central European Time and Greenwich Mean Time, so the time you see is always right for right now.
How do I convert CET to GMT?
Enter a time in the CET box and the equivalent GMT time appears instantly, adjusted for the current offset between the two zones — including a note if it lands on the previous or next day.
Is this CET to GMT converter accurate with daylight saving?
Yes. It uses your browser's built-in time-zone database (the IANA zones behind Paris and Greenwich), which tracks daylight-saving changes automatically, so the current times and difference are correct.
What time is it in Greenwich right now?
The live clock above shows the current time in Greenwich (GMT), updating every second, alongside CET.
Does the CET to GMT time difference change?
Yes. Over the next 12 months it is 2 h behind or 1 h behind, depending on the date — see the table of periods on this page.
