September is the third and final month of the financial year's first quarter, which runs from July to September. 28 September 2030 falls a quarter of the way through the financial year that began the previous July, in the third calendar quarter of 2030 under the standard January-to-December system used across most business reporting.
Saturday 28 September 2030 is a weekend day under the standard Monday-to-Friday working pattern and does not count toward the working-day total shown above. Retail, hospitality, healthcare and emergency services staff commonly work rostered shifts on this day regardless of the standard week that applies to most other industries and workplaces across the country.
2030 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.
