January carries two fixed public holidays: New Year's Day on 1 January and Australia Day on 26 January. 13 January 2026 falls inside the 31-day month that both dates bookend, with school holidays and the Australian Open running through the weeks in between. Where either date lands on a weekend, several states shift the public holiday to the following Monday, the same rule applied to Christmas and Boxing Day later in 2026.
Tuesday 13 January 2026 is an ordinary working day in the standard Monday-to-Friday week, sitting in the first half of its week and counting toward the working-day total shown above. It follows the return-to-work adjustment of Monday and precedes the midweek point that Wednesday marks in most Australian workplaces running a standard five-day schedule.
2026 has 365 days on the calendar. Leap years add a single extra day to February, giving those years 366 days instead of 365 and shifting the day-of-year number for every date from March onward by one compared with an ordinary year. This is the only irregularity in the length of the Australian calendar year.
