UTC to AEST converter

AEST is 10 hours ahead of UTC 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

Australian Eastern Standard Time

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

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

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.

Coordinated Universal Time

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

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

UTC is the reference clock every other offset is quoted against. It has no daylight saving and 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.

UTC to AEST — questions

What time is it in AEST when it is UTC now?
AEST is currently 09:27 on Thursday, 13 August 2026 (AEST, UTC+10:00), while UTC is 23:27 (UTC+00:00). That is 10 hours ahead of the source clock right now.
How many hours ahead is AEST of UTC?
10 hours at this moment. The gap is not constant across the year: Coordinated Universal Time and Australian Eastern Standard 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 AEST on daylight saving time right now?
No. Australia/Sydney is on AEST (UTC+10:00) at the moment.
When does AEST 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 UTC and AEST?
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 AEST in code?
Use Australia/Sydney. Abbreviations like AEST 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.
