What is AEST in BST?

British Time is 11 hours behind

Australian Eastern Time is on UTC+11:00 and British Time is on UTC+0:00 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 British 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 28, 2027British Time is 11 hours behind
  2. March 28, 2027 – April 4, 2027British Time is 10 hours behind
  3. April 4, 2027 – October 3, 2027British Time is 9 hours behind
  4. October 3, 2027 – October 31, 2027British Time is 10 hours behind
  5. October 31, 2027 – onwardsBritish Time is 11 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.

Scheduling between the two

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

A note on BST: it can also mean Bangladesh Standard Time (UTC+6). This page means British Summer Time.

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

British Time (GMT) is used in the whole United Kingdom. In winter the UK is on GMT; from late March to late October it is on BST, an hour ahead.
