What is ACST in CET?

Central European Time is 9 hours 30 minutes behind

Australian Central Time is on UTC+10:30 and Central European Time is on UTC+1:00 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 Central European 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, 2027Central European Time is 9 hours 30 minutes behind
  2. March 28, 2027 – April 4, 2027Central European Time is 8 hours 30 minutes behind
  3. April 4, 2027 – October 3, 2027Central European Time is 7 hours 30 minutes behind
  4. October 3, 2027 – October 31, 2027Central European Time is 8 hours 30 minutes behind
  5. October 31, 2027 – onwardsCentral European Time is 9 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

Scheduling between the two

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

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

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