UTC and AEDT on the World Map
The map below highlights the UTC (Coordinated Universal Time) and AEDT (Australian Eastern Daylight Time) timezone regions across the globe.
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 – 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 vs AEDT: Offsets, DST and Best Call Times
UTC runs on Coordinated Universal Time (UTC) at UTC+00:00. AEDT runs on Australian Eastern Daylight Time (AEDT) at UTC+11:00. That puts UTC 11 hours ahead of AEDT — a difference of +11h at the current offsets.
In practice, when it is 9:00 AM in UTC it is 8:00 PM in AEDT. Midnight in UTC is 11:00 AM in AEDT. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert UTC to AEDT time
- Scheduling a call from UTC to AEDT: a 10:00 AM start in UTC lands at 9:00 PM in AEDT, so you can confirm the slot without doing the arithmetic yourself.
- Handling a +11h gap: UTC and AEDT 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 AEDT is 8:00 PM in UTC.
- Booking travel or deliveries: tracking AEDT local time against UTC keeps pickup windows and arrival estimates honest across the +11h offset.
- Always state the zone abbreviation, not just the hour. "3:00 PM UTC" 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 UTC takes the early slot, the next week AEDT does.
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.
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.
Best time to call between UTC and AEDT
With a +11h offset there is no overlap inside a normal 9 AM – 5 PM day. AEDT opens at 9:00 AM AEDT, which is 8:00 PM in UTC, so real-time calls need an early-morning or late-evening slot on one side.
Business hours overlap
UTC and AEDT have no shared working hours because of the +11h gap. Teams need to alternate early starts or rely on asynchronous handovers.
UTC is 11 hours ahead of AEDT (UTC UTC+00:00 → AEDT UTC+11:00). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
