Autumn begins on 1 March, and by 9 March 2030 the southern states see shorter days and cooler mornings settling in. The northern wet season continues through March, with cyclone activity still active ahead of its April end, while the south moves out of its summer bushfire peak as the season turns over into the cooler months.
Any deadline or bill payment due on Saturday 9 March 2030 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.
Contracts and legal deadlines that specify calendar days count every day from 9 March 2030 including weekends and public holidays, while deadlines specified in working or business days count only the days this page includes in its working-day total. The difference between the two conventions can shift a deadline by several days once weekends and holidays are counted.
