What is ACST in EAT?

East Africa Time is 7 hours 30 minutes behind

Australian Central Time is on UTC+10:30 and East Africa Time is on UTC+3:00 right now. Australian Central Time is on daylight saving, so its clocks read ACDT. The gap changes during the year — see below.

When the difference changes

Australian Central Time and East 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, 2027East Africa Time is 7 hours 30 minutes behind
  2. April 4, 2027 – October 3, 2027East Africa Time is 6 hours 30 minutes behind
  3. October 3, 2027 – onwardsEast Africa Time is 7 hours 30 minutes 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 Central Time

Sunday, April 4, 2027

Clocks go back one hour — 3:00 am becomes 2:00 am local time, and the zone is on ACST after that.

East Africa Time

No clock changes

East Africa Time stays on EAT all year, so its offset from UTC never moves.

Australian Central Time (ACDT) is used in South Australia and the Northern Territory, on a half-hour offset from the east coast

East Africa Time (EAT) is used in Kenya, Tanzania, Uganda and Ethiopia
