15 January 2027 sits in the middle of the Australian summer, when the southern states run hot and dry with bushfire risk at its seasonal peak. The tropical north sits inside its wet season, part of the cyclone season that runs from November through to April every year. Daylight saving stays in effect in New South Wales, Victoria, South Australia, Tasmania and the ACT for the whole of January, keeping evenings light well past eight in the evening across those five states.
Some employers close early or run a shortened day on Friday, ahead of the weekend that follows. 15 January 2027 falls on this day, the last of the five working days counted in the total shown above for its week, immediately before Saturday and Sunday begin the two-day break most standard working arrangements observe.
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.
