What is AEST in KST?

Korea Standard Time is 2 hours behind

Australian Eastern Time is on UTC+11:00 and Korea Standard Time is on UTC+9:00 right now. Australian Eastern Time is on daylight saving, so its clocks read AEDT. The gap changes during the year — see below.

When the difference changes

Australian Eastern Time and Korea Standard 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 – April 4, 2027Korea Standard Time is 2 hours behind
  2. April 4, 2027 – October 3, 2027Korea Standard Time is 1 hour behind
  3. October 3, 2027 – onwardsKorea Standard Time is 2 hours 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.

Daylight saving

Australian Eastern Time

Sunday, April 4, 2027

Clocks go back one hour — 3:00 am becomes 2:00 am local time, and the zone is on AEST after that.

Korea Standard Time

No clock changes

Korea Standard Time stays on KST all year, so its offset from UTC never moves.

Scheduling between the two

Working hours overlap from 11:00 am to 6:00 pm AEDT, which is 9:00 am to 4:00 pm KST. Anything inside that window falls in the normal working day at both ends.

Australian Eastern Time (AEDT) is used in Melbourne, Canberra and Brisbane. Queensland stays on AEST all year while the southern states move to AEDT.
