Converting Greenwich Mean Time to Coordinated Universal Time
Greenwich Mean Time (GMT) and Coordinated Universal Time (UTC) are separated by a 0 hours time difference. UTC is 0 hours the same as GMT. GMT is UTC+0, used in United Kingdom, Ireland, Portugal, while UTC is UTC+0.
When converting from GMT to UTC, the key reference points to remember are: 9:00 AM GMT equals 9:00 AM UTC, 12:00 PM noon GMT equals 12:00 PM UTC, and 5:00 PM GMT equals 5:00 PM UTC. The conversion table above shows every hour of the day mapped between these two time zones.
Scheduling Across GMT and UTC
For professionals scheduling meetings between GMT and UTC, finding overlapping business hours is essential. Standard business hours are typically 9:00 AM to 5:00 PM in each time zone. Given the 0 hours 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. UTC does not observe DST, staying at UTC+0 year-round. 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.
