The NRL season opens in the first week of March, and the AFL season follows in the second half of the month. 4 March 2028 falls inside the opening rounds of both national football codes, at the same point on the calendar where Melbourne's Moomba festival runs across the Victorian Labour Day long weekend each year.
Sport fixtures, markets and family events across Australia are concentrated on Saturdays more than any other day of the week. 4 March 2028 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.
The quarter containing 4 March 2028 is based on the calendar year running January to December, a separate system from the Australian financial year, which runs from 1 July to 30 June and splits into its own four quarters. Businesses often track both systems side by side, one for tax filings and one for calendar-year planning.
