Winter begins on 1 June, and by 9 June 2030 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.
Sunday 9 June 2030 is a weekend day under the standard Monday-to-Friday working pattern and does not count toward the working-day total shown above, the last day of the weekend before the working week resumes on Monday morning across most Australian workplaces and schools.
2030 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.
