It’s a moment synonymous with the fast approaching summer.
Australians will get their first glimpse of the sunny season on Sunday when daylight saving kicks in and clocks are put forward by one hour at 2am on Sunday – except in Western Australia, Northern Territory and Queensland. Christmas Island and the Cocos (Keeling) Islands don’t do daylight savings either.
It’s welcome news for night owls who can enjoy an additional hour of daylight in the evening but not so great if you were planning to sleep in on Sunday because snoozers will lose an hour of shut eye.
While many clocks on phones and smart watches will change automatically, manual clocks will need to be altered.
NSW, Victoria, South Australia, Tasmania, the ACT and Norfolk Island all welcome daylight saving.
Australia is one of 70 other countries that participate, joining the likes of the US, Canada, Mexico and New Zealand.
Even Antarctica alters its clocks.
In Australia daylight saving always begins at 2am on the first Sunday in October and ends at 2am on the first Sunday in April.
This year’s cycle comes as health experts at Monash University in Victoria warn that shifting the time by an hour interrupts people’s circadian rhythms – responsible for mood.
“As we approach the changeover to daylight saving time, the practice remains controversial to the extent that the European Union parliament has recently voted to cease recommending the practice,” professor of diabetes Paul Zimmet said last month.
“It has left individual nations to decide for themselves.”
Mood disorders are often associated with disrupted circadian clock-controlled responses.
WHAT IS IT?
Daylight saving originated in the former Canadian city of Port Arthur in 1908 when a council moved the clock forward so the people could enjoy an additional hour of sun.
Germany is thought to be the first country to fully implement it. Daylight saving didn’t exist in Australia until 1967 in Tasmania and was prompted by drought.
Other states followed suit in the early ’70s.
