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. 1 March 2030 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.
A public holiday on a Friday pairs directly with the Saturday and Sunday that follow it, producing one of the two most common three-day-weekend patterns on the Australian calendar. Friday 1 March 2030 falls on this day of the week, the last working day of its standard Monday-to-Friday week before the weekend begins.
The quarter containing 1 March 2030 is based on the calendar year running January to December, a separate system from the Australian financial year, which runs from 1 July to 30 June and splits into its own four quarters. Businesses often track both systems side by side, one for tax filings and one for calendar-year planning.
