The AFL finals series runs through most of September, culminating in the Grand Final at the very end of the month or the start of October. 4 September 2029 falls inside this finals fixture list, alongside the NRL finals running on a similar schedule, with both codes crowning premiers within weeks of each other.
The Melbourne Cup is held on the first Tuesday of November every year, a public holiday in metropolitan Melbourne. Tuesday 4 September 2029 falls on this day of the week, the same weekday the race runs on every year regardless of the date it lands on, drawing national attention well beyond Victoria's own borders.
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.
