Converting Greenwich Mean Time to Central European Time
Greenwich Mean Time (GMT) and Central European Time (CET) are separated by a 1 hour time difference. CET is 1 hour ahead of GMT. GMT is UTC+0, used in United Kingdom, Ireland, Portugal, while CET is UTC+1, used in Germany, France, Italy.
When converting from GMT to CET, the key reference points to remember are: 9:00 AM GMT equals 10:00 AM CET, 12:00 PM noon GMT equals 1:00 PM CET, and 5:00 PM GMT equals 6:00 PM CET. The conversion table above shows every hour of the day mapped between these two time zones.
Scheduling Across GMT and CET
For professionals scheduling meetings between GMT and CET, finding overlapping business hours is essential. Standard business hours are typically 9:00 AM to 5:00 PM in each time zone. Given the 1 hour difference, the window of overlap may be limited. Use the highlighted working hours in the conversion table above to quickly identify suitable meeting times.
Daylight Saving Time Considerations
GMT observes Daylight Saving Time, switching to BST (UTC+1) during summer months. CET observes DST, switching to CEST (UTC+2). During DST transitions, the time difference between these zones may temporarily change by 1 hour. Always verify the current offset during spring and fall transition periods.
