The Royal Queensland Show, known as the Ekka, runs in Brisbane through August every year, bringing a public holiday for the greater Brisbane area on the Wednesday of the show. 28 August 2028 falls inside the same 31-day month as this regional observance, which does not apply outside greater Brisbane and leaves the rest of Queensland working an ordinary day.
Monday 28 August 2028 is an ordinary working day for the standard Monday-to-Friday workforce and counts toward the working-day total shown above, along with the four days that follow it through to Friday, separate from the shift rosters that retail, hospitality, healthcare and emergency services run on their own patterns.
2028 has 366 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.
