AEDT and UTC on the World Map
The map below highlights the AEDT (Australian Eastern Daylight Time) and UTC (Coordinated Universal Time) timezone regions across the globe.
AEDT – Australian Eastern Daylight Time
UTC+11:00Australian Eastern Daylight Time (AEDT, UTC+11:00) is the daylight saving period in south-eastern Australia, from October to April.
- •AEDT runs from the first Sunday in October to the first Sunday in April.
- •AEDT is one hour ahead of Australian Eastern Standard Time (AEST).
- •Queensland does not observe daylight saving, so Brisbane stays on AEST.
- •During AEDT, Sydney is 16 hours ahead of New York and 11 hours ahead of UTC.
UTC – Coordinated Universal Time
UTC+00:00Coordinated Universal Time (UTC) is the world's primary time standard, used as the basis for civil time worldwide.
- •UTC is the basis for all civil time zones worldwide.
- •The abbreviation 'UTC' is a compromise between English (CUT) and French (TUC).
- •UTC is based on atomic clocks and is accurate to within a nanosecond per day.
- •Servers and databases worldwide store timestamps in UTC to avoid timezone confusion.
- •Leap seconds are occasionally added to UTC to keep it aligned with Earth's rotation.
AEDT vs UTC: Offsets, DST and Best Call Times
AEDT runs on Australian Eastern Daylight Time (AEDT) at UTC+11:00. UTC runs on Coordinated Universal Time (UTC) at UTC+00:00. That puts AEDT 11 hours behind UTC — a difference of -11h at the current offsets.
In practice, when it is 9:00 AM in AEDT it is 10:00 PM in UTC on the previous day. Midnight in AEDT is 1:00 PM in UTC. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert AEDT to UTC time
- Scheduling a call from AEDT to UTC: a 10:00 AM start in AEDT lands at 11:00 PM in UTC the previous day, so you can confirm the slot without doing the arithmetic yourself.
- Handling a -11h gap: AEDT and UTC have no overlap inside a normal 9-to-5 day, so real-time meetings need an early-morning or late-evening slot on one side. 9:00 AM in UTC is 10:00 PM in AEDT.
- Watching a live event or market open: AEDT viewers need 10:00 PM in UTC to catch a 9:00 AM start there, and 11:00 AM if the event is anchored to AEDT.
- Always state the zone abbreviation, not just the hour. "3:00 PM AEDT" is unambiguous; "3 PM" across a -11h gap is not.
- With a -11h gap there is no shared 9-to-5 window, so alternate the early start: one week AEDT takes the early slot, the next week UTC does.
About AEDT (Australian Eastern Daylight Time)
Australian Eastern Daylight Time (AEDT) is the daylight saving period in south-eastern Australia, one hour ahead of Australian Eastern Standard Time (AEST, UTC+10:00). Because Australia is in the southern hemisphere, AEDT runs through the summer — from the first Sunday in October to the first Sunday in April — which is almost exactly the reverse of the European and North American schedules. New South Wales, Victoria, Tasmania and the Australian Capital Territory observe it; Queensland and the Northern Territory do not, so Brisbane stays on AEST year round while Sydney moves to AEDT. During AEDT, Sydney is 11 hours ahead of UTC and 16 hours ahead of New York.
About UTC (Coordinated Universal Time)
Coordinated Universal Time (UTC) is the primary time standard by which the world regulates clocks and time. It is effectively the successor to GMT and is based on International Atomic Time with leap seconds added to keep it synchronized with Earth's rotation. UTC is used in aviation, computing, navigation, weather forecasting, and the International Space Station. Most programming languages and databases store timestamps in UTC.
Best time to call between AEDT and UTC
With a -11h offset there is no overlap inside a normal 9 AM – 5 PM day. UTC opens at 9:00 AM UTC, which is 10:00 PM in AEDT, so real-time calls need an early-morning or late-evening slot on one side.
Business hours overlap
AEDT and UTC have no shared working hours because of the -11h gap. Teams need to alternate early starts or rely on asynchronous handovers.
AEDT is 11 hours behind UTC (AEDT UTC+11:00 → UTC UTC+00:00). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
