What is CET in ACST?

Australian Central Time is 9 hours 30 minutes ahead

Central European Time is on UTC+1:00 and Australian Central Time is on UTC+10:30 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

Central European Time and Australian Central 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, 2027Australian Central Time is 9 hours 30 minutes ahead
  2. March 28, 2027 – April 3, 2027Australian Central Time is 8 hours 30 minutes ahead
  3. April 3, 2027 – October 2, 2027Australian Central Time is 7 hours 30 minutes ahead
  4. October 2, 2027 – October 31, 2027Australian Central Time is 8 hours 30 minutes ahead
  5. October 31, 2027 – onwardsAustralian Central Time is 9 hours 30 minutes 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.

Scheduling between the two

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

Central European Time (CET) is used in Berlin, Madrid, Rome, Amsterdam, Warsaw and Stockholm

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