Spring begins on 1 September, and by 27 September 2028 warmer days return across the southern states after the winter months. The AFL finals series runs through September, ahead of the Grand Final that follows in late September or early October, drawing national attention as one of the biggest fixtures on the Australian sporting calendar.
Meetings, project check-ins and mid-week deadlines cluster on Wednesday in most Australian workplaces running a standard five-day week. 27 September 2028 falls on this day, three working days into its week and two working days from the weekend, a common point for reviewing progress against weekly targets before the final push toward Friday.
2028 has 366 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.
