What is GMT in AEST?

Australian Eastern Time is 11 hours ahead

Greenwich Mean Time is on UTC+0:00 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

Greenwich Mean 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 3, 2027Australian Eastern Time is 11 hours ahead
  2. April 3, 2027 – October 2, 2027Australian Eastern Time is 10 hours ahead
  3. October 2, 2027 – onwardsAustralian Eastern Time is 11 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

Greenwich Mean Time

No clock changes

Greenwich Mean Time stays on GMT 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

There is no overlap between a nine-to-six working day in Greenwich and one in Sydney — the gap is too wide. A call has to sit early or late for one side. Early morning in Greenwich is the usual compromise, since that is late afternoon or evening in Sydney.

Greenwich Mean Time (GMT) is used in as a fixed UTC+0 offset. Note that the UK itself leaves GMT every summer — see British Time below.

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