The winter solstice falls in the third week of June every year, the shortest day and longest night on the Australian calendar. 28 June 2026 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.
Retail, hospitality, healthcare and emergency services rosters regularly schedule staff to work on Sundays as part of standard shift patterns that do not follow the Monday-to-Friday week. 28 June 2026 falls on Sunday, a working day for these shift-based industries even though it sits outside the standard working-day count above.
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 2026 can show a different total depending on which state's calendar applies to 28 June. Interstate businesses need to check more than one state's list before setting a national deadline.
