AEST to CET Time Converter
Central European Time (CET) is currently 9 hours behind Australian Eastern Standard Time (AEST). AEST is UTC+10 and CET is UTC+1. 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 4:00 PM to 9:00 PM in AEST, which is 7:00 AM to 12:00 PM in CET. 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?

AEST is UTC+10. Sydney and Melbourne switch to AEDT (UTC+11) from October to April, while Brisbane stays on AEST year round.
CET is UTC+1, used across most of continental Europe in winter. The region switches to CEST (UTC+2) from late March to late October.
