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. 14 December 2026 falls inside this 31-day month, at the height of the Australian retail and travel calendar for the year.
Monday 14 December 2026 is the first working day of its week. Any bill, deadline or rostered task set for the preceding Saturday or Sunday moves to this date under standard business-day rules, and the working-day count above treats it as day one of a fresh five-day working stretch that runs through to Friday, before the weekend resets the cycle again.
Contracts and legal deadlines that specify calendar days count every day from 14 December 2026 including weekends and public holidays, while deadlines specified in working or business days count only the days this page includes in its working-day total. The difference between the two conventions can shift a deadline by several days once weekends and holidays are counted.
