The Australian Open runs in Melbourne throughout January, and the Big Bash cricket season plays out across the same weeks. 12 January 2026 sits inside this national sporting calendar, alongside the height of the wet season across the tropical north and the peak of the summer beach season in the southern capital cities, before both the cricket and tennis seasons wind down in February.
Monday 12 January 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.
The quarter containing 12 January 2026 is based on the calendar year running January to December, a separate system from the Australian financial year, which runs from 1 July to 30 June and splits into its own four quarters. Businesses often track both systems side by side, one for tax filings and one for calendar-year planning.
