September is the third and final month of the financial year's first quarter, which runs from July to September. 23 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.
The week containing Monday 23 September 2030 is counted from this date under the standard week-numbering convention used on this page, with weeks running Monday to Sunday rather than Sunday to Saturday. This convention affects rostering, payroll cycles and any planning done in weekly blocks across Australian workplaces that pay staff or schedule shifts on a weekly basis.
The week number shown for 23 September 2030 counts full weeks from the start of 2030, a figure used in payroll cycles, rostering and any planning done in weekly or fortnightly blocks rather than by calendar month. Businesses running fortnightly pay runs rely on this figure to track which of the two alternating pay weeks a date falls in.
