The NRL season opens in the first week of March, and the AFL season follows in the second half of the month. 13 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.
Monday 13 March 2028 is the first working day of its week. Any bill, deadline or rostered task set for the preceding Saturday or Sunday moves to this date under standard business-day rules, and the working-day count above treats it as day one of a fresh five-day working stretch that runs through to Friday, before the weekend resets the cycle again.
The working-day count on this page excludes both weekend days and any public holiday declared for the state selected, so the same date in 2028 can show a different total depending on which state's calendar applies to 13 March. Interstate businesses need to check more than one state's list before setting a national deadline.
