11:00 GMT to AEDT

11:00 GMT on 13 August 2026 is
21:00 AEST
9:00 PM · Thursday, 13 August 2026 · UTC+10:00
Two answers, and the difference matters. Read literally, AEDT is a fixed +11:00 offset, which puts 11:00 GMT at 22:00. But Australia/Sydney is on AEST on this date, so the clock on the wall there reads 21:00. If a human wrote "11:00 GMT", they almost certainly meant the wall clock.

Daylight saving right now

Australian Eastern Daylight Time

Australia/Sydney is currently on AEST (UTC+10:00). That is not AEDT — this page is named for the abbreviation people search for, and tells you the truth about which one is actually in force.

next change: Sun, 4 Oct 2026 03:00 local → AEDT (51 days, clocks go forward)

AEDT is UTC+11, in force in Sydney and Melbourne from the first Sunday in October to the first Sunday in April.

Greenwich Mean Time

Etc/GMT is on GMT (UTC+00:00).

no clock change scheduled — fixed at UTC+00:00

GMT is UTC+0 and never shifts. The UK observes GMT in winter only — in summer it is on BST (UTC+1), so "GMT" on a British invite dated in July usually means BST.

Best time to call green = 09:00–18:00 on both sides

No overlap inside a 09:00–18:00 day on both sides. Someone has to take an early or late slot — the table below shows exactly which hours are least bad.

GMT to AEDT — questions

What is 11:00 GMT in AEDT?
11:00 GMT is 21:00 (9:00 PM) in Australian Eastern Daylight Time, computed for 13 August 2026 using the AEST rules in force that day.
Does the answer change during the year?
Yes, whenever either side changes its clocks. On this date the destination is on AEST (UTC+10:00); at other times of year the same 11:00 GMT lands on a different local hour. That is why this page recomputes from tzdata on every request instead of storing a fixed answer.
