Spring is fully established across the country by 21 October 2029, with milder days and longer evenings standard in every state during October. The financial year's second quarter, October to December, begins alongside this seasonal shift, three months out from the 30 June financial year close.
A public holiday that falls on a Sunday sits inside the weekend rather than beside it, and whether a substitute day off applies to the following Monday depends on the specific holiday and the state. Sunday 21 October 2029 falls on this day of the week, at the close of the weekend, immediately before the working week resumes.
The quarter containing 21 October 2029 is based on the calendar year running January to December, a separate system from the Australian financial year, which runs from 1 July to 30 June and splits into its own four quarters. Businesses often track both systems side by side, one for tax filings and one for calendar-year planning.
