Which zone this page means. AEST applies in winter; AEDT (UTC+11) applies from the first Sunday in October to the first Sunday in April. Australian seasons are reversed, so summer time runs over the southern summer. Queensland stays on AEST all year. CET is winter time; CEST (UTC+2) applies from the last Sunday in March to the last Sunday in October. Europe changes on different dates from the United States, so the gap to US zones shifts for a few weeks each spring and autumn.
AEST is ahead of CET by 8 hours today
On 28 August 2026, Australian Eastern Standard Time is on AEST at UTC+10:00 and Central European Time is on CEST at UTC+02:00. The gap between them is 8 hours, with CET behind. So 9:00 am in AEST is 1:00 am in CET, and 5:00 pm in AEST is 9:00 am in CET. Going the other way, see CET to AEST.
The gap is not constant, and that is the part that catches people out
Australian Eastern Standard Time is currently on standard time and changes next on 4 October 2026, when clocks go forward an hour. Central European Time is currently observing daylight saving and changes next on 25 October 2026. Because the two zones change on different dates — AU rules for AEST and EU rules for CET — there are a few weeks each year when the usual gap between them is an hour out. That window is the single most common source of a missed call between these two zones, and it is why a page that quotes only the nominal offset is wrong for part of the year.
When you can actually both be at work
Taking a working day as 9:00 am to 5:00 pm local at each end, there are 0 overlapping hours in a normal day. There is none: the two working days do not touch at all, so any live meeting between Australian Eastern Standard Time and Central European Time has to sit outside somebody's normal hours. The table above shows which end has the shorter stretch to give up.
Zone rules are set by legislation and change, sometimes at short notice. This page is built against tzdata 2026a, last reviewed 2026-08-18. Quarterly. Zone rules change by legislation, sometimes at short notice. Version and review date are shown on every zone page. The converter above reads your browser's own copy of the zone database, so if a rule has changed since this page was built the live answer follows the new rule — and so does everything above, which is worked out from the same database when you open the page.
Every convention used above — whether the start date counts, how month ends are clamped, which holidays close an office — is written out on the methodology page, including the daylight-saving rules behind the 8-hour gap above.
