September is the third and final month of the financial year's first quarter, which runs from July to September. 13 September 2029 falls a quarter of the way through the financial year that began the previous July, in the third calendar quarter of 2029 under the standard January-to-December system used across most business reporting.
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 13 September 2029 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 2029 can show a different total depending on which state's calendar applies to 13 September. Interstate businesses need to check more than one state's list before setting a national deadline.
