Understanding the -9h Gap: AEDT vs CAT
AEDT runs on Australian Eastern Daylight Time (AEDT) at UTC+11:00. CAT runs on Central Africa Time (CAT) at UTC+02:00. That puts AEDT 9 hours behind CAT — a difference of -9h at the current offsets.
In practice, when it is 9:00 AM in AEDT it is 12:00 AM in CAT. Midnight in AEDT is 3:00 PM in CAT. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert AEDT to CAT time
- Scheduling a call from AEDT to CAT: a 10:00 AM start in AEDT lands at 1:00 AM in CAT, so you can confirm the slot without doing the arithmetic yourself.
- Handling a -9h gap: AEDT and CAT 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 CAT is 12:00 AM in AEDT.
- Keeping family and friends in sync: knowing that 8:00 PM in AEDT is 11:00 AM in CAT makes it easy to avoid calling at 3 AM.
- 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 CAT 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 CAT (Central Africa Time)
Central Africa Time (CAT) is fixed at UTC+02:00 all year across a broad belt of southern and central Africa, including Zimbabwe, Zambia, Mozambique, Malawi, Rwanda, Burundi and the eastern Democratic Republic of the Congo. None of these countries observes daylight saving time, so CAT never shifts. It is the same offset as South Africa Standard Time (SAST) and the winter version of Central European Time, which makes CAT a convenient bridge between African, European and Middle Eastern schedules — Harare is level with Johannesburg all year and one hour ahead of Lagos.
Best time to call between AEDT and CAT
With a -9h offset there is no overlap inside a normal 9 AM – 5 PM day. CAT opens at 9:00 AM CAT, 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 CAT 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 CAT (AEDT UTC+11:00 → CAT 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.
