EDT and AEDT on the World Map
The map below highlights the EDT (Eastern Daylight Time) and AEDT (Australian Eastern Daylight Time) timezone regions across the globe.
EDT – Eastern Daylight Time
UTC-04:00Eastern Daylight Time (EDT) is the daylight saving time observed in the Eastern Time Zone, 4 hours behind UTC.
- •EDT is observed from the second Sunday of March to the first Sunday of November.
- •During EDT, the US East Coast is only 4 hours behind London (instead of 5).
- •Not all EST locations switch to EDT – Panama and Jamaica stay on EST year-round.
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.
Comparing Time Zones: EDT and AEDT
EDT runs on Eastern Daylight Time (EDT) at UTC-04:00. AEDT runs on Australian Eastern Daylight Time (AEDT) at UTC+11:00. That puts EDT 15 hours ahead of AEDT — a difference of +15h at the current offsets.
In practice, when it is 9:00 AM in EDT it is 12:00 AM in AEDT on the next day. Midnight in EDT is 3:00 PM in AEDT. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert EDT to AEDT time
- Scheduling a call from EDT to AEDT: a 10:00 AM start in EDT lands at 1:00 AM in AEDT the next day, so you can confirm the slot without doing the arithmetic yourself.
- Handling a +15h gap: EDT 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 12:00 AM in EDT.
- Booking travel or deliveries: tracking AEDT local time against EDT keeps pickup windows and arrival estimates honest across the +15h offset.
- Always state the zone abbreviation, not just the hour. "3:00 PM EDT" is unambiguous; "3 PM" across a +15h gap is not.
- With a +15h gap there is no shared 9-to-5 window, so alternate the early start: one week EDT takes the early slot, the next week AEDT does.
About EDT (Eastern Daylight Time)
Eastern Daylight Time (EDT) is used during the summer months (second Sunday of March to the first Sunday of November) in the Eastern Time Zone. During EDT, clocks are advanced by one hour to take advantage of longer daylight hours. Not all locations in the Eastern Time Zone observe DST – Panama, Jamaica, and most of the Caribbean remain on EST year-round.
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 EDT and AEDT
With a +15h offset there is no overlap inside a normal 9 AM – 5 PM day. AEDT opens at 9:00 AM AEDT, which is 12:00 AM in EDT, so real-time calls need an early-morning or late-evening slot on one side.
Business hours overlap
EDT and AEDT have no shared working hours because of the +15h gap. Teams need to alternate early starts or rely on asynchronous handovers.
EDT is 15 hours ahead of AEDT (EDT UTC-04:00 → 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.
