The winter solstice falls in the third week of June every year, the shortest day and longest night on the Australian calendar. 2 June 2030 sits close to this turning point, after which daylight hours slowly lengthen again toward summer, even though winter continues for two more months, through July and August.
Any deadline or bill payment due on Sunday 2 June 2030 moves to the following Monday under standard business-day rules, since Sunday sits outside the working week this page counts by default. This convention applies consistently across contracts, invoices and statutory deadlines throughout Australia, regardless of which state or territory is involved.
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.
