ANZAC Day falls on the fixed date of 25 April, marked nationwide with dawn services regardless of which day of the week it lands on. 21 April 2027 falls inside the same 30-day month, alongside Easter, which moves from year to year but falls within or close to April in most years across the Australian calendar.
The Ekka public holiday in greater Brisbane is held on a Wednesday during the Royal Queensland Show each August, one of the few recurring public holidays fixed to this day of the week. Wednesday 21 April 2027 falls on the same weekday as this regional observance, which applies only within greater Brisbane and not to the rest of Queensland.
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 21 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.
