Spring begins on 1 September, and by 26 September 2027 warmer days return across the southern states after the winter months. The AFL finals series runs through September, ahead of the Grand Final that follows in late September or early October, drawing national attention as one of the biggest fixtures on the Australian sporting calendar.
Sunday 26 September 2027 is a weekend day under the standard Monday-to-Friday working pattern and does not count toward the working-day total shown above, the last day of the weekend before the working week resumes on Monday morning across most Australian workplaces and schools.
The quarter containing 26 September 2027 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.
