Grape harvest finishes in most Australian wine regions during March, timed to the arrival of autumn across the southern states. School Term 1 assessments concentrate in March across every state, and 18 March 2029 falls inside this seasonal window, ahead of the Term 1 school holidays that begin the following month in April.
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 18 March 2029 falls on this day of the week, at the close of the weekend, immediately before the working week resumes.
The working-day count on this page excludes both weekend days and any public holiday declared for the state selected, so the same date in 2029 can show a different total depending on which state's calendar applies to 18 March. Interstate businesses need to check more than one state's list before setting a national deadline.
