While daylight savings usually occurs over the October long weekend, this year some states won't turn their clocks forward until the following Sunday.

Clocks will be turned forward one hour on Sunday 7 October from 2.00am in the states of New South Wales, Victoria, the ACT, South Australia and Tasmania,

Daylight savings always falls on the first Sunday of October.

This usually coincides with the public holiday, but for the first time since 2012 it will occur seven days after the start of October.

Anglican Church League in Sydney has issued a community service announcement on their website, highlighting the date the time changes in bold.

"Might be worth reminding congregations," the website reads.

Most smartphone devices and computers automatically adjust the time without any human intervention, but analogue clocks will need to be manually changed.

Daylight savings is still a contentious issue for some states with Queensland, the Northern Territory and Western Australia not taking part.

Confusion when milking cows, and curtains fading, are some of the arguments used against moving the time forward.
