Everything You Need to Know About AEDT and CEST Time
AEDT runs on Australian Eastern Daylight Time (AEDT) at UTC+11:00. CEST runs on Central European Summer Time (CEST) at UTC+02:00. That puts AEDT 9 hours behind CEST — a difference of -9h at the current offsets.
In practice, when it is 9:00 AM in AEDT it is 12:00 AM in CEST. Midnight in AEDT is 3:00 PM in CEST. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert AEDT to CEST time
- Scheduling a call from AEDT to CEST: a 10:00 AM start in AEDT lands at 1:00 AM in CEST, so you can confirm the slot without doing the arithmetic yourself.
- Handling a -9h gap: AEDT and CEST have no overlap inside a normal 9-to-5 day, so real-time meetings need an early-morning or late-evening slot on one side. 9:00 AM in CEST is 12:00 AM in AEDT.
- Watching a live event or market open: AEDT viewers need 12:00 AM in CEST to catch a 9:00 AM start there, and 9:00 AM if the event is anchored to AEDT.
- Always state the zone abbreviation, not just the hour. "3:00 PM AEDT" is unambiguous; "3 PM" across a -9h gap is not.
- With a -9h gap there is no shared 9-to-5 window, so alternate the early start: one week AEDT takes the early slot, the next week CEST does.
About AEDT (Australian Eastern Daylight Time)
Australian Eastern Daylight Time (AEDT) is the daylight saving period in south-eastern Australia, one hour ahead of Australian Eastern Standard Time (AEST, UTC+10:00). Because Australia is in the southern hemisphere, AEDT runs through the summer — from the first Sunday in October to the first Sunday in April — which is almost exactly the reverse of the European and North American schedules. New South Wales, Victoria, Tasmania and the Australian Capital Territory observe it; Queensland and the Northern Territory do not, so Brisbane stays on AEST year round while Sydney moves to AEDT. During AEDT, Sydney is 11 hours ahead of UTC and 16 hours ahead of New York.
About CEST (Central European Summer Time)
Central European Summer Time (CEST) is observed from the last Sunday of March to the last Sunday of October across most of Europe. During CEST, clocks are 2 hours ahead of UTC. The EU has debated abolishing seasonal clock changes since 2019.
Best time to call between AEDT and CEST
With a -9h offset there is no overlap inside a normal 9 AM – 5 PM day. CEST opens at 9:00 AM CEST, which is 12:00 AM in AEDT, so real-time calls need an early-morning or late-evening slot on one side.
Business hours overlap
AEDT and CEST have no shared working hours because of the -9h gap. Teams need to alternate early starts or rely on asynchronous handovers.
AEDT is 9 hours behind CEST (AEDT UTC+11:00 → CEST UTC+02:00). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
