GMT (Greenwich Mean Time) is 1 hours behind CET (Central European Time). This means when it's 12:00 PM in Paris (CET), it's 11:00 AM in London (GMT).
The best time to call from CET to GMT is during overlapping business hours. For CET callers, schedule between 12:00 PM - 5:00 PM CET to ensure both parties are within standard business hours.
The time difference may change during daylight saving transitions if one region observes DST while the other doesn't. Central European Time (UTC+1 (CET) / UTC+2 (CEST)) and Greenwich Mean Time (UTC+0 (GMT) / UTC+1 (BST)) may have different DST schedules.
CET includes cities like Paris. GMT includes cities like London. Both time zones cover important business and cultural centers.
In 2025, DST in North America starts on March 9 at 2:00 AM and ends on November 2 at 2:00 AM. Other regions may have different DST schedules or not observe DST at all.
