Daylight saving returns on the first Sunday of October in New South Wales, Victoria, South Australia, Tasmania and the ACT, putting the clocks forward an hour. 23 October 2030 falls in this month of change, while Queensland, Western Australia and the Northern Territory keep the same clock they run all year, unaffected by the switch.
Wednesday 23 October 2030 sits at the midpoint of the standard working week, between Monday's start and Friday's finish. Australians commonly call this point in the week hump day, marking the transition from the first half of the working week to the second, with two working days already complete and two still remaining before the weekend begins.
The week number shown for 23 October 2030 counts full weeks from the start of 2030, a figure used in payroll cycles, rostering and any planning done in weekly or fortnightly blocks rather than by calendar month. Businesses running fortnightly pay runs rely on this figure to track which of the two alternating pay weeks a date falls in.
