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 2026 falls inside the same 31-day month as both events, alongside the school year's final weeks.
Any deadline or bill payment due on Sunday 20 December 2026 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.
The hours and minutes shown in the countdown to 20 December 2026 are calculated against the clock and time zone set on the device displaying this page, and the countdown reaches zero at midnight local to that device. Two people in different time zones will see slightly different figures at the exact same moment, each reflecting their own local midnight.
