Australia spans 5 time zones; these dates are computed from Australia/Sydney. Regions that opt out of daylight saving — where they exist — keep standard time through the summer.
Transitions are computed directly from the IANA time-zone database at build time, not from a hand-kept table — if the rules change, these dates change with the next daily build.
FAQ
When do the clocks change in Australia?
Saturday, 3 April 2027, at 03:00 local time, when clocks go back one hour.
Why does the time difference to other countries wobble?
Countries change their clocks on different dates — Europe and North America are a week or more apart — so for a few weeks each spring and autumn the usual difference is temporarily an hour off. Every overlap and difference figure on this site reads the current offsets from the IANA time-zone database, so those weeks are handled automatically.
