Understanding the -14h Gap: AEST vs EDT
AEST runs on Australian Eastern Standard Time (AEST) at UTC+10:00. EDT runs on Eastern Daylight Time (EDT) at UTC-04:00. That puts AEST 14 hours behind EDT — a difference of -14h at the current offsets.
In practice, when it is 9:00 AM in AEST it is 7:00 PM in EDT on the previous day. Midnight in AEST is 10:00 AM in EDT. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert AEST to EDT time
- Scheduling a call from AEST to EDT: a 10:00 AM start in AEST lands at 8:00 PM in EDT the previous day, so you can confirm the slot without doing the arithmetic yourself.
- Handling a -14h gap: AEST 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 7:00 PM in AEST.
- Watching a live event or market open: AEST viewers need 7:00 PM in EDT to catch a 9:00 AM start there, and 2:00 PM if the event is anchored to AEST.
- Always state the zone abbreviation, not just the hour. "3:00 PM AEST" is unambiguous; "3 PM" across a -14h gap is not.
- With a -14h gap there is no shared 9-to-5 window, so alternate the early start: one week AEST takes the early slot, the next week EDT does.
About AEST (Australian Eastern Standard Time)
Australian Eastern Standard Time (AEST) is used in the eastern states of Australia including New South Wales, Victoria, Queensland, Tasmania, and the ACT. During summer (October to April), NSW, VIC, TAS, and ACT switch to Australian Eastern Daylight Time (AEDT, UTC+11:00), while Queensland remains on AEST year-round.
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 AEST and EDT
With a -14h offset there is no overlap inside a normal 9 AM – 5 PM day. EDT opens at 9:00 AM EDT, which is 7:00 PM in AEST, so real-time calls need an early-morning or late-evening slot on one side.
Business hours overlap
AEST and EDT have no shared working hours because of the -14h gap. Teams need to alternate early starts or rely on asynchronous handovers.
AEST is 14 hours behind EDT (AEST UTC+10:00 → 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.
