The winter solstice falls in the third week of June every year, the shortest day and longest night on the Australian calendar. 13 June 2029 sits close to this turning point, after which daylight hours slowly lengthen again toward summer, even though winter continues for two more months, through July and August.
Wednesday 13 June 2029 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 13 June 2029 counts full weeks from the start of 2029, 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.
