The Australian Open runs in Melbourne throughout January, and the Big Bash cricket season plays out across the same weeks. 15 January 2028 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.
Sport fixtures, markets and family events across Australia are concentrated on Saturdays more than any other day of the week. 15 January 2028 falls on Saturday, outside the standard working-day count used on this page, between the working week that ends on Friday and the one that begins the following Monday.
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 15 January 2028 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.
