The Australian Open runs in Melbourne throughout January, and the Big Bash cricket season plays out across the same weeks. 31 January 2027 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.
Sunday 31 January 2027 is a weekend day under the standard Monday-to-Friday working pattern and does not count toward the working-day total shown above, the last day of the weekend before the working week resumes on Monday morning across most Australian workplaces and schools.
A public holiday that falls on a Monday or a Friday produces a three-day weekend without using any annual leave, which is why long-weekend planning around 31 January 2027 depends on which day of the week the nearest public holiday falls on. A midweek holiday delivers no such automatic extension, though many workers bridge it with a single day of leave.
