What is ACST in AKST?

Alaska Time is 19 hours 30 minutes behind

Australian Central Time is on UTC+10:30 and Alaska Time is on UTC−9:00 right now. Australian Central Time is on daylight saving, so its clocks read ACDT. The gap changes during the year — see below.

When the difference changes

Australian Central Time and Alaska Time do not change their clocks on the same dates, so the gap between them is not the same all year. Most converters show only today’s figure. These are the periods ahead:

  1. Now – March 14, 2027Alaska Time is 19 hours 30 minutes behind
  2. March 14, 2027 – April 4, 2027Alaska Time is 18 hours 30 minutes behind
  3. April 4, 2027 – October 3, 2027Alaska Time is 17 hours 30 minutes behind
  4. October 3, 2027 – November 7, 2027Alaska Time is 18 hours 30 minutes behind
  5. November 7, 2027 – onwardsAlaska Time is 19 hours 30 minutes behind

Periods shorter than a day are not listed. Each zone changes at its own local time, so on a date when both move there are a few hours when the gap is briefly something else.

Scheduling between the two

Working hours overlap from 9:00 am to 2:00 pm ACDT, which is 1:30 pm to 6:30 pm AKST. Anything inside that window falls in the normal working day at both ends.

Australian Central Time (ACDT) is used in South Australia and the Northern Territory, on a half-hour offset from the east coast
