Autumn begins on 1 March, and by 23 March 2026 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.
The week containing Monday 23 March 2026 is counted from this date under the standard week-numbering convention used on this page, with weeks running Monday to Sunday rather than Sunday to Saturday. This convention affects rostering, payroll cycles and any planning done in weekly blocks across Australian workplaces that pay staff or schedule shifts on a weekly basis.
The working-day count on this page excludes both weekend days and any public holiday declared for the state selected, so the same date in 2026 can show a different total depending on which state's calendar applies to 23 March. Interstate businesses need to check more than one state's list before setting a national deadline.
