Whale migration season runs along much of the eastern and western coastlines through May, one of the seasonal markers of the Australian mid-year. 21 May 2029 falls inside this stretch, as days continue shortening ahead of the winter solstice the following month and the ski season's opening in the Snowy Mountains and Victorian Alps not far behind it.
The week containing Monday 21 May 2029 is counted from this date under the standard week-numbering convention used on this page, with weeks running Monday to Sunday rather than Sunday to Saturday. This convention affects rostering, payroll cycles and any planning done in weekly blocks across Australian workplaces that pay staff or schedule shifts on a weekly basis.
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 2029 can show a different total depending on which state's calendar applies to 21 May. Interstate businesses need to check more than one state's list before setting a national deadline.
