Daylight saving ends on the first Sunday of April in New South Wales, Victoria, South Australia, Tasmania and the ACT, putting the clocks back an hour. 23 April 2027 falls in the month where those five states move off daylight time, while Queensland, Western Australia and the Northern Territory keep the same clock they have run all year without any change.
A public holiday on a Friday pairs directly with the Saturday and Sunday that follow it, producing one of the two most common three-day-weekend patterns on the Australian calendar. Friday 23 April 2027 falls on this day of the week, the last working day of its standard Monday-to-Friday week before the weekend begins.
A public holiday that falls on a Monday or a Friday produces a three-day weekend without using any annual leave, which is why long-weekend planning around 23 April 2027 depends on which day of the week the nearest public holiday falls on. A midweek holiday delivers no such automatic extension, though many workers bridge it with a single day of leave.
