Love it or hate it, it’s that time of year again, but there’s literally no point in losing any sleep over it!

It’s time to turn your clock back one hour this Sunday morning for the end of Daylight Saving Time (DST). Millions of Australians are approaching the end of DST, when all but three states and territories will wind their clocks back by an hour and potentially gain an extra hour of sleep by doing so.

However, not all states and territories opt in.

NSW, Victoria, South Australia, Tasmania and the ACT all observe DST, while Queensland, Western Australia and the Northern Territory do not.

Most smartphones and computers will automatically update their clocks when DST ends, but some older models may need to be updated manually.

Most microwaves and ovens that display the time will also have to be changed manually.

DST is the practice of setting the clocks forward one hour from standard time during the summer months and back again in autumn, to make better use of natural daylight.

Reportedly, the residents of Thunder Bay, Ontario, Canada, claim to have been the first to turn their clocks forward by one hour in 1908 when the town was known as Port Arthur.

However, DST is reported to have caught on globally when first introduced in 1916 by the Germans, closely followed by Britain and France, to save on artificial lighting and in turn, fuel during wartime.

Daylight Saving Time is now used in more than 70 countries worldwide, affecting more than one billion people each year. The start and end dates vary from one country to another.

A question always asked when DST comes around each year is about putting your clock forward or back, but a useful little saying can help with that “spring forward, fall (autumn) back”.

You set your clock forward in the spring when DST starts, losing one hour and then back one hour when it ends in autumn, therefore regaining the one hour.

Although most people change their clocks before going to bed the night before, DST will officially come to an end on Sunday, 5 April when clocks go back one hour at 3am Australian Eastern Daylight Time (AEDT).

The official time changes again at 2am on Sunday, 4 October, pushing the clock forward to 3am.
