Summer officially begins on 1 December, and by 14 December 2029 the country runs its hottest, longest-daylight stretch of the year. December closes 2029 in the fourth calendar quarter, the final quarter under the standard January-to-December system used on this page.
Some employers close early or run a shortened day on Friday, ahead of the weekend that follows. 14 December 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 December 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.
