Daylight saving right now

Greenwich Mean Time

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

no clock change scheduled — this zone is 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.

Central European Time

Europe/Paris is on CEST (UTC+02:00).

next change: Sun, 25 Oct 2026 02:00 local → CET (72 days)

CET is UTC+1, the winter clock for most of mainland western Europe. From late March to late October the same countries run CEST (UTC+2).

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

7 overlapping working hours. The longest run is 11:00–18:00 CET, which is 09:00–16:00 GMT.

CET to GMT — questions

What time is it in GMT when it is CEST now?
GMT is currently 01:00 on Thursday, 13 August 2026 (GMT, UTC+00:00), while CET is 03:00 (UTC+02:00). That is 2 hours behind the source clock right now.
How many hours behind is GMT of CET?
2 hours at this moment. The gap is not constant across the year: Central European Time and Greenwich Mean 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 GMT on daylight saving time right now?
No. Etc/GMT is on GMT (UTC+00:00) at the moment.
Does GMT observe daylight saving time?
No. Etc/GMT stays on UTC+00:00 all year, so the difference from CET only moves when CET itself changes.
What is the best time to schedule a call between CET and GMT?
There are 7 hours of overlap where both sides are inside a 09:00-18:00 working day. The longest block is 11:00–18:00 CET, which is 09:00–16:00 GMT. 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 GMT in code?
Use Etc/GMT. Abbreviations like GMT 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+00:00 instead will be wrong the moment the rules change.
