Converting Central European Time to Greenwich Mean Time
Central European Time (CET) and Greenwich Mean Time (GMT) are separated by a 1 hour time difference. GMT is 1 hour behind CET. CET is UTC+1, used in Germany, France, Italy, while GMT is UTC+0, used in United Kingdom, Ireland, Portugal.
When converting from CET to GMT, the key reference points to remember are: 9:00 AM CET equals 8:00 AM GMT, 12:00 PM noon CET equals 11:00 AM GMT, and 5:00 PM CET equals 4:00 PM GMT. The conversion table above shows every hour of the day mapped between these two time zones.
Scheduling Across CET and GMT
For professionals scheduling meetings between CET and GMT, 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
CET observes Daylight Saving Time, switching to CEST (UTC+2) during summer months. GMT observes DST, switching to BST (UTC+1). 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.
