How to Convert CET to GMT
Converting between Central European Time and Greenwich Mean Time means accounting for a 1 hour gap — here's how to do it in under 10 seconds with no sign-up.
Pick the date and time in Central European Time (UTC +1) that you want to convert. Hit "Now" to load the current CET time instantly, or use "+1h" to step forward and compare.
The equivalent Greenwich Mean Time (UTC +0) time appears immediately. Since GMT is 1 hour behind of CET, most daytime conversions stay on the same calendar day.
Click "Copy Time" to grab the GMT result for your calendar or message. Use "+1d" to check how the conversion shifts across dates — useful when Daylight Saving Time changes the gap.
Why Choose Our CET to GMT Converter
When someone in Central Europe suggests 10:00 AM CET, that's 9:00 AM GMT. This converter shows the overlap so both sides agree on one slot — no back-and-forth.
Late-night CET times can land on a different date in GMT because of the 1 hour offset. The converter labels "next day" or "previous day" next to the result so you never send a message a day early or miss a deadline.
Daylight Saving adjustments can widen or narrow the CET–GMT gap by an hour. During transition weeks many people get it wrong. This converter pulls the current UTC offsets automatically, so the result is right even on the changeover day.
Product launches, sports matches, and webinars are often announced in CET. Convert the event time to GMT so you know exactly when to tune in — with a 1 hour difference, a morning event in Central Europe falls during work hours in Universal.
