Why people convert AEDT to AKST time
- Scheduling a call from AEDT to AKST: a 10:00 AM start in AEDT lands at 2:00 PM in AKST the previous day, so you can confirm the slot without doing the arithmetic yourself.
- Handling a -20h gap: AEDT and AKST 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 AKST is 1:00 PM in AEDT.
- Coordinating a AEDT-based team with AKST 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 -20h gap is not.
- With a -20h gap there is no shared 9-to-5 window, so alternate the early start: one week AEDT takes the early slot, the next week AKST 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 AKST (Alaska Standard Time)
Alaska Standard Time (AKST) is used in nearly all of Alaska. Due to Alaska's vast geographic size, the Aleutian Islands use Hawaii-Aleutian Standard Time instead. During summer months, Alaska switches to Alaska Daylight Time (AKDT, UTC-08:00).
Best time to call between AEDT and AKST
With a -20h offset there is no overlap inside a normal 9 AM – 5 PM day. AKST opens at 9:00 AM AKST, which is 1:00 PM in AEDT, so real-time calls need an early-morning or late-evening slot on one side.
Business hours overlap
AEDT and AKST have no shared working hours because of the -20h gap. Teams need to alternate early starts or rely on asynchronous handovers.
AEDT is 20 hours behind AKST (AEDT UTC+11:00 → AKST UTC-09:00). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
