Summer officially begins on 1 December, and by 9 December 2028 the country runs its hottest, longest-daylight stretch of the year. December closes 2028 in the fourth calendar quarter, the final quarter under the standard January-to-December system used on this page.
Saturday 9 December 2028 is a weekend day under the standard Monday-to-Friday working pattern and does not count toward the working-day total shown above. Retail, hospitality, healthcare and emergency services staff commonly work rostered shifts on this day regardless of the standard week that applies to most other industries and workplaces across the country.
A public holiday that falls on a Monday or a Friday produces a three-day weekend without using any annual leave, which is why long-weekend planning around 9 December 2028 depends on which day of the week the nearest public holiday falls on. A midweek holiday delivers no such automatic extension, though many workers bridge it with a single day of leave.
