Daylight savings: What you need to know

Daylight savings: What you need to know

Aussies are preparing for daylight savings to hit their state, which impacts everyone except Western Australia, Queensland and the Northern Territory.

This means that the clocks are put forward by one hour at 2 am on Sunday, and many associate daylight savings with the start of summer.

Many clocks on smartphones and smartwatches will change automatically, but manual clocks will need to be altered.

However, this year's cycle comes with a health warning as experts from Monash University in Victoria warn that the time shift interrupts people's circadian rhythms, which are 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.”

Australia is one of 70 other countries that participate in daylight savings, with other countries including the US, Mexico, New Zealand and Antarctica.
