CET to AEST Converter

Standard business hours (9 AM–5 PM, Mon–Fri) in Central European Time and Australian Eastern Time don't overlap on the same weekday. Australian Eastern Time is 8 hours ahead of Central European Time.

With some flexibility, there’s a workable window outside standard hours:

• 7 AM–12 PM in Central European Time (3 PM–8 PM in Australian Eastern Time) — suggest 9:00 AM Central European Time (5:00 PM Australian Eastern Time).

This means an early start or late finish for one side, but it’s a reasonable slot for a one-off meeting.

Central European Time is also known as CET, or CEST. To call France, dial +33.

Australian Eastern Time is also known as AEST, or AEDT. To call Australia, dial +61.

Australian Eastern Time is approximately 10,550 miles east of Central European Time.

Both zones observe daylight saving time, but they transition on different dates.

Central European Time: next transition on Sunday, October 25, 2026.

Australian Eastern Time: next transition on Sunday, October 4, 2026.

Central European Time and Australian Eastern Time are in opposite hemispheres, so their clocks change in opposite directions about six months apart — one springs forward while the other falls back. The offset between them therefore shifts twice a year and can swing by up to two hours across the seasons, more than a typical same-hemisphere pair. Recurring meetings will need re-checking after each transition.

See the daylight saving time page for transition dates across every time zone.
