Warmer weather returns in earnest across the southern states by 13 November 2029, 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.
Tuesday 13 November 2029 carries no recurring public holiday of its own outside the first Tuesday of November, when the Melbourne Cup applies in metropolitan Melbourne. On every other date, this day of the week runs as a standard working day across the country, counted fully in the working-day total above.
The quarter containing 13 November 2029 is based on the calendar year running January to December, a separate system from the Australian financial year, which runs from 1 July to 30 June and splits into its own four quarters. Businesses often track both systems side by side, one for tax filings and one for calendar-year planning.
