Time zone in South Australia

All of South Australia keeps the same time: Australian Central Standard Time (ACST, UTC+9:30) in winter and Australian Central Daylight Time (ACDT, UTC+10:30) in summer.

Its standard offset, UTC+9:30, is not a whole number of hours, so the minutes differ too when you compare South Australia with most of the world. Only 3 of the 312 zones in the database use UTC+9:30 at any time of year.

Adelaide lies at 138.6° east, where mean solar time is UTC+9:14 (four minutes per degree of longitude). Standard time runs 16 min ahead of the sun, so on average the sun is highest at about 12:16 PM in winter and an hour later in summer.

Daylight saving time in South Australia

Yes. South Australia moves its clocks forward one hour on the first Sunday of October at 2:00 AM and back on the first Sunday of April at 3:00 AM (local time). It is in the southern hemisphere, so summer time runs from about October to April, the opposite of Europe and North America.

All coming change dates are on the Australia/Adelaide page.

Clock history of South Australia

South Australia has kept the same clocks as Adelaide since at least 1970: tzdata records both under Australia/Adelaide. Between 1970 and 2024, a daylight saving period began in 54 of the 55 years. Before 1970 local practice could differ from Adelaide’s, and tzdata does not track it separately; the year-by-year table, which starts with Adelaide’s local mean time, is on the Australia/Adelaide page.
