September is the third and final month of the financial year's first quarter, which runs from July to September. 7 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.
Friday 7 September 2029 is the last working day of the standard Monday-to-Friday week, the fifth and final working day before the weekend begins. A public holiday landing on this day of the week joins directly onto the Saturday and Sunday that follow it, forming a three-day weekend without using any annual leave.
2029 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.
