Comparing Time Zones: AEDT and EDT
AEDT runs on Australian Eastern Daylight Time (AEDT) at UTC+11:00. EDT runs on Eastern Daylight Time (EDT) at UTC-04:00. That puts AEDT 15 hours behind EDT — a difference of -15h at the current offsets.
In practice, when it is 9:00 AM in AEDT it is 6:00 PM in EDT on the previous day. Midnight in AEDT is 9:00 AM in EDT. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert AEDT to EDT time
- Scheduling a call from AEDT to EDT: a 10:00 AM start in AEDT lands at 7:00 PM in EDT the previous day, so you can confirm the slot without doing the arithmetic yourself.
- Handling a -15h gap: AEDT and EDT 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 EDT is 6:00 PM in AEDT.
- Coordinating a AEDT-based team with EDT contacts: quoting times in the other side's local clock — not your own — removes the single biggest source of missed meetings.
- Always state the zone abbreviation, not just the hour. "3:00 PM AEDT" 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 AEDT takes the early slot, the next week EDT 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 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.
Best time to call between AEDT and EDT
With a -15h offset there is no overlap inside a normal 9 AM – 5 PM day. EDT opens at 9:00 AM EDT, which is 6:00 PM in AEDT, so real-time calls need an early-morning or late-evening slot on one side.
Business hours overlap
AEDT and EDT have no shared working hours because of the -15h gap. Teams need to alternate early starts or rely on asynchronous handovers.
AEDT is 15 hours behind EDT (AEDT UTC+11:00 → EDT UTC-04:00). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
