About ACDT
Australian Central Daylight Time (ACDT) is UTC+10:30. It is used in Adelaide in summer.
Australian Central Daylight Time is UTC+10:30, what South Australia keeps from October to April. Darwin stays on ACST through the summer, so for those months two cities in the same nominal zone are an hour apart — the only reason to be precise about which of the two abbreviations a meeting invitation carries.
About SAST
South Africa Standard Time (SAST) is UTC+2. It is used in South Africa, Lesotho and Eswatini.
South Africa Standard Time is UTC+2 with no daylight saving, unchanged since 1903 apart from two wartime years. The whole country keeps it, and so do Lesotho and Eswatini. Against the UK it is two hours ahead in winter and one in summer, which is the shift that catches London–Johannesburg standing calls every March and October.
Does this gap change with the seasons?
Neither ACDT nor SAST shifts with the seasons, so this 8.5-hour difference holds all year. That is unusual enough to be worth relying on: most cross-continental gaps move twice a year.
This is the reason scheduling systems store an IANA zone such as Region/City rather than an offset or an abbreviation: the zone knows its own rules and the offset does not.
Frequently asked questions
What time is 9:00 AM ACDT in SAST?
9:00 AM ACDT is 12:30 AM SAST.
Is SAST ahead of ACDT?
SAST is 8 hours 30 minutes behind ACDT.
Which time zone does this use?
ACDT is UTC+10:30 and SAST is UTC+2. Both abbreviations denote a single fixed offset, so this conversion never shifts with daylight saving — what changes is which abbreviation a place is using at the time.
