The school year ends for most students partway through December, handing over to the long summer holidays that run through January and into February of the following year. 5 December 2027 falls inside this end-of-year school stretch, the longest holiday period on the Australian school calendar.
Any deadline or bill payment due on Sunday 5 December 2027 moves to the following Monday under standard business-day rules, since Sunday sits outside the working week this page counts by default. This convention applies consistently across contracts, invoices and statutory deadlines throughout Australia, regardless of which state or territory is involved.
Contracts and legal deadlines that specify calendar days count every day from 5 December 2027 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.
