September is the third and final month of the financial year's first quarter, which runs from July to September. 22 September 2026 falls a quarter of the way through the financial year that began the previous July, in the third calendar quarter of 2026 under the standard January-to-December system used across most business reporting.
Tuesday 22 September 2026 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.
2026 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.
