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. 28 October 2029 carries this public holiday in those three states, with every other state and territory working through an ordinary day.
A public holiday that falls on a Sunday sits inside the weekend rather than beside it, and whether a substitute day off applies to the following Monday depends on the specific holiday and the state. Sunday 28 October 2029 falls on this day of the week, at the close of the weekend, immediately before the working week resumes.
2029 has 365 days on the calendar. Leap years add a single extra day to February, giving those years 366 days instead of 365 and shifting the day-of-year number for every date from March onward by one compared with an ordinary year. This is the only irregularity in the length of the Australian calendar year.
