Frequently asked questions
What is the time difference between CET and ACST?+
CET is UTC+01:00 and ACST is UTC+09:30 in standard time. The gap between them changes during the year if either place observes daylight saving, so enter a date to see the difference on that day.
Does CET observe daylight saving time?+
No. CET stays on UTC+01:00 all year.
Does ACST observe daylight saving time?+
No. ACST stays on UTC+09:30 all year.
Why does one local time sometimes have two answers?+
When clocks go back, the hour before the change repeats, so that local reading happens twice and both instants are valid. When clocks go forward, the skipped hour never occurs, so that reading has no matching instant at all. The converter reports both cases rather than guessing.
