Daylight saving remains in effect throughout March in New South Wales, Victoria, South Australia, Tasmania and the ACT, with the clocks not going back until the first Sunday of April. 23 March 2027 still runs on daylight time in those five jurisdictions, one of the last full months of extended evening light before the shift into shorter winter days.
Tuesday 23 March 2027 carries no recurring public holiday of its own outside the first Tuesday of November, when the Melbourne Cup applies in metropolitan Melbourne. On every other date, this day of the week runs as a standard working day across the country, counted fully in the working-day total above.
The week number shown for 23 March 2027 counts full weeks from the start of 2027, a figure used in payroll cycles, rostering and any planning done in weekly or fortnightly blocks rather than by calendar month. Businesses running fortnightly pay runs rely on this figure to track which of the two alternating pay weeks a date falls in.
