Warmer weather returns in earnest across the southern states by 28 November 2030, 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.
A public holiday landing on a Thursday sits one day short of the weekend, and workers commonly take the Friday after it as annual leave to turn a single day off into a four-day break. Thursday 28 November 2030 falls on this day of the week, one working day ahead of Friday and two ahead of the weekend that follows it.
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 2030 can show a different total depending on which state's calendar applies to 28 November. Interstate businesses need to check more than one state's list before setting a national deadline.
