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.

Every hour as its own page

GMT to AEDT — questions

What time is it in AEDT when it is GMT now?
AEDT is currently 10:25 on Thursday, 13 August 2026 (AEST, UTC+10:00), while GMT is 00:25 (UTC+00:00). That is 10 hours ahead of the source clock right now.
How many hours ahead is AEDT of GMT?
10 hours at this moment. The gap is not constant across the year: Greenwich Mean Time and Australian Eastern Daylight Time change clocks on different dates (or one of them not at all), so a difference you hard-code in summer can be an hour wrong in winter. The table on this page is computed from the current tzdata rules, not from a fixed offset.
Is AEDT on daylight saving time right now?
No. Australia/Sydney is on AEST (UTC+10:00) at the moment.
When does AEDT next change its clocks?
Australia/Sydney next changes on Sunday, 04 October 2026 at 03:00 local time, when it moves forward 60 minutes and the abbreviation becomes AEDT (UTC+11:00). That is 51 days away. This date comes from the IANA tzdata rules currently in force, so it updates if a government changes the law.
Is there any working-hours overlap between GMT and AEDT?
Not inside a normal 09:00-18:00 day on both sides — the 10-hour gap is too wide. One party has to take an early or late slot; the hour table above shows exactly which hours land where so you can pick the least painful one.
Which IANA timezone name should I use for AEDT in code?
Use Australia/Sydney. Abbreviations like AEDT are ambiguous and not resolvable by most libraries — Python's ZoneInfo, Java's ZoneId, Go's time.LoadLocation and JavaScript's Intl all expect the IANA name. Hard-coding UTC+10:00 instead will be wrong the moment the rules change.
