AEDT — Australian Eastern Daylight Time
AEDT is Australian Eastern Daylight Time, 11 hours ahead of UTC. It is a fixed offset: unlike a time zone, it does not change with the season — the zones that use it switch to a different abbreviation instead.

Is AEDT in force right now?
A zone only carries this abbreviation for part of the year. This is which of them were on it at 2 Aug 2026 07:46 UTC; the list is re-derived against your own clock when scripts load.
On AEDT now
- No zone was using AEDT at that moment.
Using a different abbreviation
- Australia/Sydney — on AEST (UTC+10)
- Australia/Melbourne — on AEST (UTC+10)
- Australia/Hobart — on AEST (UTC+10)
AEDT alternates with AEST across the year.
Writing “AEDT” for a date in the other half of the year is the most common time zone mistake in meeting invitations.
Convert AEDT to other time zones
City clocks reflect whatever their zone is doing; where a city observes daylight saving time, its difference from AEDT changes twice a year. Use the time zone converter for a specific date.

Why AEDT is not an identifier
AEDT is shorthand, not a standard. There is no registry of time zone abbreviations, no authority that assigns them, and nothing preventing two regions from adopting the same three letters — which is what makes codes like IST and CST unusable without context.
For anything a machine will read — a calendar invitation, a database column, an API response — use the IANA identifier of the zone (Australia/Sydney, for example) or an explicit UTC offset alongside the date. The identifier survives a change in the law; AEDT and its 11 hours offset do not.
Frequently asked questions
What does AEDT stand for?
AEDT stands for Australian Eastern Daylight Time. It is 11 hours ahead of UTC, written UTC+11.
What is AEDT in UTC?
AEDT is UTC+11. To convert an AEDT time to UTC, subtract 11 hours.
What is the difference between AEDT and AEST?
AEDT is the daylight saving form and AEST the standard form of the same zones. The two are one hour apart and only one is ever in force at a time, so a recurring meeting written "AEDT" shifts by an hour when the clocks change.
Which time zone should I use instead of AEDT?
Use an IANA identifier — Australia/Sydney, Australia/Melbourne and Australia/Hobart for Australian Eastern Daylight Time — or state the UTC offset with the date. Abbreviations are not identifiers: they are not unique, they are not registered anywhere, and half of them change with the season. Calendar software resolves this automatically when you pick a city rather than typing letters.
