What is EET in ACST?

Australian Central Time is 6 hours 30 minutes ahead

Eastern European Time is on UTC+3:00 and Australian Central Time is on UTC+9:30 right now. Eastern European Time is on daylight saving, so its clocks read EEST. The gap changes during the year — see below.

When the difference changes

Eastern 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:

Now – October 3, 2026Australian Central Time is 6 hours 30 minutes ahead
October 3, 2026 – October 25, 2026Australian Central Time is 7 hours 30 minutes ahead
October 25, 2026 – March 28, 2027Australian Central Time is 8 hours 30 minutes ahead
March 28, 2027 – April 3, 2027Australian Central Time is 7 hours 30 minutes ahead
April 3, 2027 – October 2, 2027Australian Central Time is 6 hours 30 minutes ahead
October 2, 2027 – onwardsAustralian Central Time is 7 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.
