Why people convert CAT to AEDT time
- Scheduling a call from CAT to AEDT: a 10:00 AM start in CAT lands at 7:00 PM in AEDT, so you can confirm the slot without doing the arithmetic yourself.
- Handling a +9h gap: CAT 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 CAT.
- Coordinating a CAT-based team with AEDT contacts: quoting times in the other side's local clock — not your own — removes the single biggest source of missed meetings.
- Always state the zone abbreviation, not just the hour. "3:00 PM CAT" 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 CAT takes the early slot, the next week AEDT does.
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.
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 CAT 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 CAT, so real-time calls need an early-morning or late-evening slot on one side.
Business hours overlap
CAT and AEDT have no shared working hours because of the +9h gap. Teams need to alternate early starts or rely on asynchronous handovers.
CAT is 9 hours ahead of AEDT (CAT 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.
