Daylight saving right now

Greenwich Mean Time

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

no clock change scheduled — this zone is 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.

Australian Eastern Daylight Time

Australia/Sydney is on AEST (UTC+10:00).

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

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

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

AEDT to GMT — questions

What time is it in GMT when it is AEST now?
GMT is currently 01:00 on Thursday, 13 August 2026 (GMT, UTC+00:00), while AEDT is 11:00 (UTC+10:00). That is 10 hours behind the source clock right now.
How many hours behind is GMT of AEDT?
10 hours at this moment. The gap is not constant across the year: Australian Eastern Daylight Time and Greenwich Mean 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 GMT on daylight saving time right now?
No. Etc/GMT is on GMT (UTC+00:00) at the moment.
Does GMT observe daylight saving time?
No. Etc/GMT stays on UTC+00:00 all year, so the difference from AEDT only moves when AEDT itself changes.
Is there any working-hours overlap between AEDT and GMT?
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 GMT in code?
Use Etc/GMT. Abbreviations like GMT 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+00:00 instead will be wrong the moment the rules change.
