Father's Day is observed on the first Sunday of September every year, shaping retail trade for the week either side of it. 14 September 2029 falls inside the same 30-day month as this observance, in the first month of the Australian spring, as warmer weather returns across the southern half of the country.
Some employers close early or run a shortened day on Friday, ahead of the weekend that follows. 14 September 2029 falls on this day, the last of the five working days counted in the total shown above for its week, immediately before Saturday and Sunday begin the two-day break most standard working arrangements observe.
The quarter containing 14 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.
