GMT is 1 hour behind CET. CET (Central European Time) is UTC+1 and GMT (Greenwich Mean Time) is UTC+0.
How do I convert CET to GMT?
Take your time in CET and subtract 1 hours. For example, 9:00 AM CET is 8:00 AM in GMT. The live clocks at the top of this page always show the current conversion.
Does daylight saving time affect CET to GMT conversion?
Yes. CET switches to CEST (UTC+2) in summer and GMT switches to BST (UTC+1) in summer, so the gap between the two zones changes during DST periods. The live clocks on this page use the IANA timezone database and always reflect the correct current offset automatically.
What is the best time for a meeting between CET and GMT?
Look for overlap between 9:00 AM-6:00 PM working hours in both zones using the conversion table above. GMT is 1 hour behind CET, so there is normally several hours of business-hours overlap.
