CET to AEST Time Converter
Australian Eastern Standard Time (AEST) is currently 9 hours ahead of Central European Time (CET). CET is UTC+1 and AEST is UTC+10. The table below converts every hour of the day between the two, and the call planner shows where working hours line up.
Best Time for a Call
There is no overlap between 9:00 AM and 5:00 PM office hours in these two zones. Stretching to early mornings and evenings, the workable window runs from 7:00 AM to 12:00 PM in CET, which is 4:00 PM to 9:00 PM in AEST. One side ends up outside normal hours, so alternating who takes the awkward slot is a fair way to handle recurring calls.

Does the Difference Change During the Year?
CET and AEST are fixed offsets, so the difference between them never changes.

AEST is UTC+10. Sydney and Melbourne switch to AEDT (UTC+11) from October to April, while Brisbane stays on AEST year round.
