GMT (Greenwich Mean Time) is 11 hours behind AEST (Australian Eastern Standard Time). This means when it's 12:00 PM in Sydney (AEST), it's 1:00 AM in London (GMT).
The best time to call from AEST to GMT is during overlapping business hours. For AEST callers, schedule between 12:00 PM - 5:00 PM AEST to ensure both parties are within standard business hours.
The time difference may change during daylight saving transitions if one region observes DST while the other doesn't. Australian Eastern Standard Time (UTC+10 (AEST) / UTC+11 (AEDT)) and Greenwich Mean Time (UTC+0 (GMT) / UTC+1 (BST)) may have different DST schedules.
AEST includes cities like Sydney. GMT includes cities like London. Both time zones cover important business and cultural centers.
In 2025, DST in North America starts on March 9 at 2:00 AM and ends on November 2 at 2:00 AM. Other regions may have different DST schedules or not observe DST at all.
