January carries two fixed public holidays: New Year's Day on 1 January and Australia Day on 26 January. 7 January 2027 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 2027.
A public holiday landing on a Thursday sits one day short of the weekend, and workers commonly take the Friday after it as annual leave to turn a single day off into a four-day break. Thursday 7 January 2027 falls on this day of the week, one working day ahead of Friday and two ahead of the weekend that follows it.
2027 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.
