Shared working hours
They do not overlap at all. A 09:00–17:00 working day in South Africa Standard Time ends 1 hour before the Australian Eastern Time one begins, so any live call sits outside somebody's working hours.
The shortest reach is the edges: early morning in SAST against late evening in AEST, or the other way round.
When the difference changes
The two zones move their clocks on different dates, so the gap takes more than one value. These are the stretches of 2026:
| Dates | AEST is | Why |
|---|---|---|
| 1 January – 4 April | 9 hours ahead of | — |
| 4 April – 3 October | 8 hours ahead of | Australian Eastern Time clocks go back one hour |
| 3 October – 1 January | 9 hours ahead of | Australian Eastern Time clocks go forward one hour |
Dates are South Africa Standard Time local dates for 2026. Transition dates move by a few days from year to year; the rule each country follows does not.
About South Africa Standard Time
South Africa is a fixed UTC+2 and has never used daylight saving. Being in the southern hemisphere, its working day overlaps Europe most comfortably and North America least — and unlike its northern counterparts nothing about that changes through the year.
Cities on this clock: Johannesburg, Cape Town, Khartoum.
About Australian Eastern Time
Sydney, Melbourne and Canberra run at UTC+10 as AEST and UTC+11 as AEDT, changing on the first Sunday in October and the first Sunday in April. Queensland does not change at all, so Brisbane matches Sydney for about half the year and sits an hour behind it for the rest — on the same "Eastern" label.
Cities on this clock: Sydney, Melbourne.
How the difference is worked out
The gap between South Africa Standard Time and Australian Eastern Time is not one number. The two zones change their clocks on different dates, so for part of the year the difference is 9 hours and for the rest it is something else — the table above lists each stretch of 2026 with the date it starts and which country's clocks moved.
With both zones on their own standard time — daylight saving not in force anywhere — Australian Eastern Time is 8 hours ahead of South Africa Standard Time. That figure never changes; everything else on this page follows from it plus whichever clocks have moved.
Every figure here comes from the IANA time zone database via your browser's own Intl engine, using the zone ids Africa/Johannesburg and Australia/Sydney. Nothing is looked up on a server and nothing about your visit is recorded.
