Summer officially begins on 1 December, and by 6 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.
Workplaces commonly schedule their heaviest meeting load on Thursday, leaving Friday clearer for closing out the week's remaining work. 6 December 2029 falls on this day, the fourth working day of its standard Monday-to-Friday week, with one working day remaining before the weekend begins and the count above resets for Monday.
The quarter containing 6 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.
