How many hours apart are AEDT and GMT?
GMT is 11 hours behind AEDT. In everyday terms, once you know the time on one side you just subtract 11 hours to get the other — so a call between Sydney and London (winter) is always 11 hours apart.
What's the current time in GMT?
Right now the time in Greenwich Mean Time (GMT) is Monday, June 29, 2026 · 5:54:05 PM. It ticks every second, so you’re always looking at the live GMT clock.
And what time is it in AEDT?
And in Australian Eastern Daylight Time (AEDT), it’s currently Tuesday, June 30, 2026 · 4:54:05 AM. Compare the two and the 11 hours gap is easy to see.
When is a good time to schedule a AEDT to GMT meeting?
For example, a 9:00 AM AEDT meeting takes place at 10:00 PM GMT (−1 day). The trick is to aim for a slot that lands inside normal working hours on both sides. Once you’ve found a time, hit Share on the converter to copy a link with the time built in — easy to send to a colleague. Juggling three or more zones? The meeting planner highlights the hours that overlap for everyone.
Does daylight saving time change the AEDT–GMT difference?
The labels AEDT and GMT are fixed offsets, so the result on this page is always exact. One side switches between standard and summer time while the other stays put, so the real-world gap can shift by an hour for part of the year. It's worth checking which label a region is actually using before you lock in a time.
How accurate is this AEDT to GMT conversion?
We don’t guess. AEDT and GMT times are worked out from the official IANA time zone database, the trusted standard that operating systems use worldwide. Because daylight-saving rules and regional offsets do change over time, we track those updates rather than relying on a fixed number — which is exactly where many converters slip up.

Frequently asked questions
How many hours behind AEDT is GMT?
GMT is 11 hours behind AEDT — a fixed 11 hours difference, since both are fixed-offset labels.
What time is it in GMT when it's 12:00 PM AEDT?
When it's 12:00 PM (noon) AEDT, it's 1:00 AM GMT.
Do AEDT or GMT use daylight saving time?
Australian Eastern Daylight Time (AEDT) observes daylight saving, alternating with AEST; Greenwich Mean Time (GMT) is a fixed offset with no daylight saving.
Why might the real-world AEDT–GMT difference change during the year?
The labels AEDT and GMT are fixed offsets, so this converter is always exact. But Australian Eastern Daylight Time's region switches between standard and summer time, so for part of the year you may actually want AEST to GMT. Always check which label a region is currently using before you schedule.
