Summer officially begins on 1 December, and by 29 December 2026 the country runs its hottest, longest-daylight stretch of the year. December closes 2026 in the fourth calendar quarter, the final quarter under the standard January-to-December system used on this page.
Tuesday 29 December 2026 is an ordinary working day in the standard Monday-to-Friday week, sitting in the first half of its week and counting toward the working-day total shown above. It follows the return-to-work adjustment of Monday and precedes the midweek point that Wednesday marks in most Australian workplaces running a standard five-day schedule.
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.
