Labour Day falls on the first Monday of March in Western Australia and on the second Monday of March in Victoria and Tasmania. New South Wales, Queensland, South Australia, the Northern Territory and the ACT do not hold a Labour Day public holiday in March at all, so the long weekend applies only in the three states that observe it on these dates.
Shift rosters in retail, hospitality, healthcare and emergency services regularly schedule staff on Tuesdays as part of rotating patterns that do not follow the standard Monday-to-Friday week. Tuesday 20 March 2029 falls within this rostering system for shift-based industries, separate from the standard working-day count above that assumes a five-day week.
The quarter containing 20 March 2029 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.
