Summer begins on 1 December, and December carries the two biggest fixed public holidays of the year: Christmas Day on 25 December and Boxing Day on 26 December. 23 December 2027 falls inside this 31-day month, at the height of the Australian retail and travel calendar for the year.
Workplaces commonly schedule their heaviest meeting load on Thursday, leaving Friday clearer for closing out the week's remaining work. 23 December 2027 falls on this day, the fourth working day of its standard Monday-to-Friday week, with one working day remaining before the weekend begins and the count above resets for Monday.
The working-day count on this page excludes both weekend days and any public holiday declared for the state selected, so the same date in 2027 can show a different total depending on which state's calendar applies to 23 December. Interstate businesses need to check more than one state's list before setting a national deadline.
