AEST to UTC converter

UTC is 10 hours behind AEST right now. Live clocks on both sides, a direct time input, the full 24-hour table with a permalink per hour, and the real daylight-saving state — computed from the IANA tz database on every request, never from a stored offset.

Daylight saving right now

Coordinated Universal Time

UTC is currently on UTC (UTC+00:00).

no clock change scheduled — this zone is fixed at UTC+00:00

UTC is the reference clock every other offset is quoted against. It has no daylight saving and never shifts.

Australian Eastern Standard Time

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

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

AEST is UTC+10. Because Australia is in the southern hemisphere its daylight saving runs October to April — Sydney is on AEDT (UTC+11) during the northern winter. Brisbane never shifts.

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.

AEST to UTC — questions

What time is it in UTC when it is AEST now?
UTC is currently 00:16 on Thursday, 13 August 2026 (UTC, UTC+00:00), while AEST is 10:16 (UTC+10:00). That is 10 hours behind the source clock right now.
How many hours behind is UTC of AEST?
10 hours at this moment. The gap is not constant across the year: Australian Eastern Standard Time and Coordinated Universal 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 UTC on daylight saving time right now?
No. UTC is on UTC (UTC+00:00) at the moment.
Does UTC observe daylight saving time?
No. UTC stays on UTC+00:00 all year, so the difference from AEST only moves when AEST itself changes.
Is there any working-hours overlap between AEST and UTC?
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 UTC in code?
Use UTC. Abbreviations like UTC 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.
