In most years, the long weekend in early October in some states marks the beginning of daylight saving time for those that observe it.
However, SafeWork SA is reminding people that because of the way the calendar falls this year, daylight saving will not take effect until next weekend.
That is because daylight saving comes into effect in South Australia, NSW, Victoria, the ACT and Tasmania from the first Sunday in October, while this year, the public holiday (Labour Day in NSW, South Australia and the ACT) falls on Monday, 1 October.
“[As such] instead, daylight saving period will commence on Sunday, 7 October, when clocks go forward one hour at 2am, and continue until Sunday, 7 April next year,” the agency said.
“In 2019, daylight saving will once again align with the October long weekend.”
The annual change sees the number of time zones across Australia increase from three to five, given that Queensland, the Northern Territory and WA do not observe it.
Daylight saving time operates between the first Sunday of October through to the first Sunday of April each year.
Queensland will also mark a public holiday on Monday, 1 October for the Queen’s birthday, which most other states and territories observe on the second Monday of June (while WA marked the holiday this week on Monday, 24 September).
In an interesting piece of trivia, the far western NSW town of Broken Hill actually observes SA time during daylight saving rather than NSW time. That is because it sits much closer to Adelaide (around 490 kilometres) than Sydney (around 1,040 km).
