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.
Workplaces commonly schedule their heaviest meeting load on Thursday, leaving Friday clearer for closing out the week's remaining work. 22 March 2029 falls on this day, the fourth working day of its standard Monday-to-Friday week, with one working day remaining before the weekend begins and the count above resets for Monday.
The week number shown for 22 March 2029 counts full weeks from the start of 2029, 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.
