The Boxing Day Test and the Sydney to Hobart yacht race both begin on 26 December every year, two of the most recognisable fixtures on the Australian sporting calendar. 20 December 2029 falls inside the same 31-day month as both events, alongside the school year's final weeks.
A public holiday landing on a Thursday sits one day short of the weekend, and workers commonly take the Friday after it as annual leave to turn a single day off into a four-day break. Thursday 20 December 2029 falls on this day of the week, one working day ahead of Friday and two ahead of the weekend that follows it.
Contracts and legal deadlines that specify calendar days count every day from 20 December 2029 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.
