No national public holiday falls in August. 21 August 2027 runs as an ordinary working day across the country outside greater Brisbane, sitting between the mid-winter quiet of July and the arrival of spring the following month on 1 September, in one of the more uninterrupted working stretches of the year for most Australian workplaces.
Sport fixtures, markets and family events across Australia are concentrated on Saturdays more than any other day of the week. 21 August 2027 falls on Saturday, outside the standard working-day count used on this page, between the working week that ends on Friday and the one that begins the following Monday.
2027 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.
