Understanding the +8h Gap: CEST vs AEST
CEST runs on Central European Summer Time (CEST) at UTC+02:00. AEST runs on Australian Eastern Standard Time (AEST) at UTC+10:00. That puts CEST 8 hours ahead of AEST — a difference of +8h at the current offsets.
In practice, when it is 9:00 AM in CEST it is 5:00 PM in AEST. Midnight in CEST is 8:00 AM in AEST. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert CEST to AEST time
- Scheduling a call from CEST to AEST: a 10:00 AM start in CEST lands at 6:00 PM in AEST, so you can confirm the slot without doing the arithmetic yourself.
- Handling a +8h gap: CEST and AEST 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 AEST is 5:00 PM in CEST.
- Booking travel or deliveries: tracking AEST local time against CEST keeps pickup windows and arrival estimates honest across the +8h offset.
- Always state the zone abbreviation, not just the hour. "3:00 PM CEST" is unambiguous; "3 PM" across a +8h gap is not.
- With a +8h gap there is no shared 9-to-5 window, so alternate the early start: one week CEST takes the early slot, the next week AEST 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 AEST (Australian Eastern Standard Time)
Australian Eastern Standard Time (AEST) is used in the eastern states of Australia including New South Wales, Victoria, Queensland, Tasmania, and the ACT. During summer (October to April), NSW, VIC, TAS, and ACT switch to Australian Eastern Daylight Time (AEDT, UTC+11:00), while Queensland remains on AEST year-round.
Best time to call between CEST and AEST
With a +8h offset there is no overlap inside a normal 9 AM – 5 PM day. AEST opens at 9:00 AM AEST, which is 5:00 PM in CEST, so real-time calls need an early-morning or late-evening slot on one side.
Business hours overlap
CEST and AEST have no shared working hours because of the +8h gap. Teams need to alternate early starts or rely on asynchronous handovers.
CEST is 8 hours ahead of AEST (CEST UTC+02:00 → AEST UTC+10:00). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
