Spring is fully established across the country by 11 October 2026, 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.
Retail, hospitality, healthcare and emergency services rosters regularly schedule staff to work on Sundays as part of standard shift patterns that do not follow the Monday-to-Friday week. 11 October 2026 falls on Sunday, a working day for these shift-based industries even though it sits outside the standard working-day count above.
2026 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.
