Labour Day falls on the first Monday of October in New South Wales, South Australia and the ACT, the only three jurisdictions observing the holiday on this date. 18 October 2029 carries this public holiday in those three states, with every other state and territory working through an ordinary day.
A public holiday landing on a Thursday sits one day short of the weekend, and workers commonly take the Friday after it as annual leave to turn a single day off into a four-day break. Thursday 18 October 2029 falls on this day of the week, one working day ahead of Friday and two ahead of the weekend that follows it.
The week number shown for 18 October 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.
