What is AEST in WAT?

West Africa Time is 10 hours behind

Australian Eastern Time is on UTC+11:00 and West Africa Time is on UTC+1:00 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 West Africa 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, 2027West Africa Time is 10 hours behind
  2. April 4, 2027 – October 3, 2027West Africa Time is 9 hours behind
  3. October 3, 2027 – onwardsWest Africa Time is 10 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.

West Africa Time

No clock changes

West Africa Time stays on WAT all year, so its offset from UTC never moves.

Scheduling between the two

There is no overlap between a nine-to-six working day in Sydney and one in Lagos — 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 Lagos.

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

West Africa Time (WAT) is used in Nigeria, Algeria, Angola and Cameroon
