What is JST in AEST?

Australian Eastern Time is 2 hours ahead

Japan Standard Time is on UTC+9:00 and Australian Eastern Time is on UTC+11:00 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

Japan Standard Time and Australian Eastern 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, 2027Australian Eastern Time is 2 hours ahead
  2. April 4, 2027 – October 3, 2027Australian Eastern Time is 1 hour ahead
  3. October 3, 2027 – onwardsAustralian Eastern Time is 2 hours ahead

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

Japan Standard Time

No clock changes

Japan Standard Time stays on JST all year, so its offset from UTC never moves.

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.

Scheduling between the two

Working hours overlap from 9:00 am to 4:00 pm JST, which is 11:00 am to 6:00 pm AEDT. 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.
