Converting Greenwich Mean Time to Australian Eastern Standard Time
Greenwich Mean Time (GMT) and Australian Eastern Standard Time (AEST) are separated by a 10 hours time difference. AEST is 10 hours ahead of GMT. GMT is UTC+0, used in United Kingdom, Ireland, Portugal, while AEST is UTC+10, used in Australia.
When converting from GMT to AEST, the key reference points to remember are: 9:00 AM GMT equals 7:00 PM AEST, 12:00 PM noon GMT equals 10:00 PM AEST, and 5:00 PM GMT equals 3:00 AM AEST. The conversion table above shows every hour of the day mapped between these two time zones.
Scheduling Across GMT and AEST
For professionals scheduling meetings between GMT and AEST, finding overlapping business hours is essential. Standard business hours are typically 9:00 AM to 5:00 PM in each time zone. Given the 10 hours difference, the window of overlap may be limited, making early morning or late evening calls necessary for one party. 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. AEST observes DST, switching to AEDT (UTC+11). 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.
