The Melbourne Cup runs on the first Tuesday of November every year, a public holiday in metropolitan Melbourne and a national event followed everywhere else. 18 November 2029 falls inside the same 30-day month as this race, at the peak of the spring racing carnival that runs across several states.
Any deadline or bill payment due on Sunday 18 November 2029 moves to the following Monday under standard business-day rules, since Sunday sits outside the working week this page counts by default. This convention applies consistently across contracts, invoices and statutory deadlines throughout Australia, regardless of which state or territory is involved.
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.
