Converting Australian Eastern Standard Time to Greenwich Mean Time
Australian Eastern Standard Time (AEST) and Greenwich Mean Time (GMT) are separated by a 10 hours time difference. GMT is 10 hours behind AEST. AEST is UTC+10, used in Australia, while GMT is UTC+0, used in United Kingdom, Ireland, Portugal.
When converting from AEST to GMT, the key reference points to remember are: 9:00 AM AEST equals 11:00 PM GMT, 12:00 PM noon AEST equals 2:00 AM GMT, and 5:00 PM AEST equals 7:00 AM GMT. The conversion table above shows every hour of the day mapped between these two time zones.
Scheduling Across AEST and GMT
For professionals scheduling meetings between AEST 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 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
AEST observes Daylight Saving Time, switching to AEDT (UTC+11) 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.
