Frequently Asked Questions
What is the time difference between CAT and AEDT?
During standard time, Australian Eastern Daylight Time is 9 hours ahead of Central Africa Time.
Does the Central Africa Time zone observe Daylight Saving Time?
None of the countries observing Central Africa Time use Daylight Saving Time. South Africa abolished DST in 1994, and no other CAT-observing nation currently applies seasonal clock changes — CAT remains permanently fixed at UTC+02:00 throughout the year.
Which major countries use Central Africa Time (CAT)?
Central Africa Time is observed by South Africa, Zimbabwe, Zambia, Botswana, Mozambique, Malawi, and Eswatini. South Africa is the zone's dominant economy, with Johannesburg functioning as the region's primary financial center and home to the Johannesburg Stock Exchange (JSE), Africa's largest equity market by capitalization.
When does AEDT start and end?
AEDT begins on the first Sunday in October at 02:00 local time, when clocks spring forward one hour from AEST (UTC+10) to AEDT (UTC+11). It ends on the first Sunday in April at 03:00 local time, when clocks fall back to AEST. In 2026, AEDT starts on October 4 and ends on April 5 — following the Southern Hemisphere summer calendar, which runs opposite to DST schedules in Europe and North America.
Is Brisbane on AEDT?
No — Queensland, including Brisbane, does not observe Daylight Saving Time and remains on AEST (UTC+10) year-round. During the AEDT period from October through April, Sydney and Melbourne advance to UTC+11 while Brisbane stays at UTC+10, creating a one-hour gap between cities that share nearly the same longitude and are otherwise in the same time zone for the other six months of the year.
