Warmer weather returns in earnest across the southern states by 4 November 2028, 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.
Any deadline or bill payment due on Saturday 4 November 2028 moves to the following Monday under standard business-day rules, since Saturday is not a working day for the Monday-to-Friday workforce this page counts by default. Shift-based industries follow their own separate rostering rules instead of this convention.
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 2028 can show a different total depending on which state's calendar applies to 4 November. Interstate businesses need to check more than one state's list before setting a national deadline.
