Daylight saving right now

Central European Summer Time

Europe/Paris is currently on CET (UTC+01:00). That is not CEST. This page is named for the abbreviation people search for, and tells you the truth about which one is actually in force.

next change: Sun, 28 Mar 2027 03:00 local → CEST (132 days, clocks go forward)

CEST is UTC+2, the summer clock for Paris, Berlin, Madrid and Rome, running from the last Sunday in March to the last Sunday in October.

Greenwich Mean Time

Etc/GMT is on GMT (UTC+00:00).

no clock change scheduled: fixed at UTC+00:00

GMT is UTC+0 and never shifts. The UK observes GMT in winter only: in summer it is on BST (UTC+1), so "GMT" on a British invite dated in July usually means BST.

Best time to call green = 09:00 to 18:00 on both sides

8 overlapping working hours. The longest run is 09:00 to 17:00 GMT, which is 10:00 to 18:00 CEST.

GMT to CEST: questions

What time is it in CEST when it is GMT now?
CEST is currently 20:46 on Sunday, 15 November 2026 (CET, UTC+01:00), while GMT is 19:46 (UTC+00:00). That is 1 hours ahead of the source clock right now.
How many hours ahead is CEST of GMT?
1 hours at this moment. The gap is not constant across the year: Greenwich Mean Time and Central European Summer Time change clocks on different dates (or one of them not at all), so a difference you hard-code in summer can be an hour wrong in winter. The table on this page is computed from the current tzdata rules, not from a fixed offset.
Is CEST on daylight saving time right now?
No. Europe/Paris is on CET (UTC+01:00) at the moment.
When does CEST next change its clocks?
Europe/Paris next changes on Sunday, 28 March 2027 at 03:00 local time, when it moves forward 60 minutes and the abbreviation becomes CEST (UTC+02:00). That is 132 days away. This date comes from the IANA tzdata rules currently in force, so it updates if a government changes the law.
What is the best time to schedule a call between GMT and CEST?
There are 8 hours of overlap where both sides are inside a 09:00-18:00 working day. The longest block is 09:00 to 17:00 GMT, which is 10:00 to 18:00 CEST. Use the calendar buttons above to drop it straight into Google Calendar, Outlook or an .ics file.
Which IANA timezone name should I use for CEST in code?
Use Europe/Paris. Abbreviations like CEST are ambiguous and not resolvable by most libraries. Python's ZoneInfo, Java's ZoneId, Go's time.LoadLocation and JavaScript's Intl all expect the IANA name. Hard-coding UTC+01:00 instead will be wrong the moment the rules change.
