School Term 3 ends toward the close of September or the start of October, depending on the state. 30 September 2029 falls inside this final stretch of Term 3, ahead of the short holiday break before Term 4 begins, the last school term of the calendar year for Australian students before the long summer break in December.
Sunday 30 September 2029 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 30 September 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.
