What is PST in AEST?

Australian Eastern Time is 19 hours ahead

Pacific Time is on UTC−8:00 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

Pacific 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:

Now – March 14, 2027Australian Eastern Time is 19 hours ahead
March 14, 2027 – April 3, 2027Australian Eastern Time is 18 hours ahead
April 3, 2027 – October 2, 2027Australian Eastern Time is 17 hours ahead
October 2, 2027 – November 7, 2027Australian Eastern Time is 18 hours ahead
November 7, 2027 – onwardsAustralian Eastern Time is 19 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.
