Winter begins on 1 June, and by 5 June 2027 the southern states run their coldest mornings of the year so far. The financial year also closes on 30 June, so June carries the full weight of both the seasonal change and the financial year close arriving in the same four weeks, a combination that makes June one of the busier months on the business calendar.
Any deadline or bill payment due on Saturday 5 June 2027 moves to the following Monday under standard business-day rules, since Saturday is not a working day for the Monday-to-Friday workforce this page counts by default. Shift-based industries follow their own separate rostering rules instead of this convention.
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.
