Daylight saving returns on the first Sunday of October in New South Wales, Victoria, South Australia, Tasmania and the ACT, putting the clocks forward an hour. 9 October 2027 falls in this month of change, while Queensland, Western Australia and the Northern Territory keep the same clock they run all year, unaffected by the switch.
A public holiday that falls on a Saturday sits inside the weekend rather than beside it, so it does not automatically create a substitute day off during the working week; whether one applies depends on the specific holiday and the state. Saturday 9 October 2027 falls on this day of the week, inside the weekend itself.
2027 has 365 days on the calendar. Leap years add a single extra day to February, giving those years 366 days instead of 365 and shifting the day-of-year number for every date from March onward by one compared with an ordinary year. This is the only irregularity in the length of the Australian calendar year.
