Why people convert AKST to AEDT time
- Scheduling a call from AKST to AEDT: a 10:00 AM start in AKST lands at 6:00 AM in AEDT the next day, so you can confirm the slot without doing the arithmetic yourself.
- Handling a +20h gap: AKST 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 5:00 AM in AKST.
- Keeping family and friends in sync: knowing that 8:00 PM in AKST is 4:00 PM in AEDT makes it easy to avoid calling at 3 AM.
- Always state the zone abbreviation, not just the hour. "3:00 PM AKST" 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 AKST takes the early slot, the next week AEDT does.
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).
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 AKST and AEDT
With a +20h offset there is no overlap inside a normal 9 AM – 5 PM day. AEDT opens at 9:00 AM AEDT, which is 5:00 AM in AKST, so real-time calls need an early-morning or late-evening slot on one side.
Business hours overlap
AKST and AEDT have no shared working hours because of the +20h gap. Teams need to alternate early starts or rely on asynchronous handovers.
AKST is 20 hours ahead of AEDT (AKST UTC-09:00 → 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.
