August is the last full month of winter. By 5 August 2030, wattle, the national floral emblem, is in bloom across much of the country, one of the clearest seasonal markers that spring is approaching in the southern states, even while the far south holds onto its coldest overnight temperatures of the year for a few more weeks.
The week containing Monday 5 August 2030 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.
2030 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.
