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. 27 August 2029 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.
A public holiday landing on a Monday produces a three-day weekend together with the preceding Saturday and Sunday, one of the two most common long-weekend patterns on the Australian calendar. Monday 27 August 2029 falls on this day of the week, at the start of a standard five-day working stretch that runs through to Friday of the same week.
2029 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.
