Everything You Need to Know About CEST and AEDT Time
CEST runs on Central European Summer Time (CEST) at UTC+02:00. AEDT runs on Australian Eastern Daylight Time (AEDT) at UTC+11:00. That puts CEST 9 hours ahead of AEDT — a difference of +9h at the current offsets.
In practice, when it is 9:00 AM in CEST it is 6:00 PM in AEDT. Midnight in CEST is 9:00 AM in AEDT. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert CEST to AEDT time
- Scheduling a call from CEST to AEDT: a 10:00 AM start in CEST lands at 7:00 PM in AEDT, so you can confirm the slot without doing the arithmetic yourself.
- Handling a +9h gap: CEST and AEDT 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 AEDT is 6:00 PM in CEST.
- Keeping family and friends in sync: knowing that 8:00 PM in CEST is 5:00 AM in AEDT makes it easy to avoid calling at 3 AM.
- Always state the zone abbreviation, not just the hour. "3:00 PM CEST" 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 CEST takes the early slot, the next week AEDT does.
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.
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.
Best time to call between CEST and AEDT
With a +9h offset there is no overlap inside a normal 9 AM – 5 PM day. AEDT opens at 9:00 AM AEDT, which is 6:00 PM in CEST, so real-time calls need an early-morning or late-evening slot on one side.
Business hours overlap
CEST and AEDT have no shared working hours because of the +9h gap. Teams need to alternate early starts or rely on asynchronous handovers.
CEST is 9 hours ahead of AEDT (CEST UTC+02:00 → AEDT UTC+11:00). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
