Warmer weather returns in earnest across the southern states by 23 November 2027, with the first genuinely hot days of the season arriving during November, ahead of summer's official start on 1 December and the cyclone season that runs through the tropical north until April.
The Melbourne Cup is held on the first Tuesday of November every year, a public holiday in metropolitan Melbourne. Tuesday 23 November 2027 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.
2027 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.
