What is ACST in CET?
Central European Time is 7 hours 30 minutes behind
Australian Central Time is on UTC+9:30 and Central European Time is on UTC+2:00 right now. Central European Time is on daylight saving, so its clocks read CEST. 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:
- Now – October 3, 2026Central European Time is 7 hours 30 minutes behind
- October 3, 2026 – October 25, 2026Central European Time is 8 hours 30 minutes behind
- October 25, 2026 – March 28, 2027Central European Time is 9 hours 30 minutes behind
- March 28, 2027 – April 3, 2027Central European Time is 8 hours 30 minutes behind
- April 3, 2027 – October 2, 2027Central European Time is 7 hours 30 minutes behind
- October 2, 2027 – onwardsCentral European Time is 8 hours 30 minutes behind
Periods shorter than a day are not listed: both zones change at 2am in their own local time, so there are a few hours on each transition date when the gap is briefly something else.
