School holidays run through January in every state and territory, with Term 1 not starting until the last week of January or the first week of February. 16 January 2028 falls inside this national school break, the longest of the four holiday periods on the Australian school calendar and the busiest month of the year for family travel to caravan parks, coastal towns and the roads that lead to them.
A public holiday that falls on a Sunday sits inside the weekend rather than beside it, and whether a substitute day off applies to the following Monday depends on the specific holiday and the state. Sunday 16 January 2028 falls on this day of the week, at the close of the weekend, immediately before the working week resumes.
The week number shown for 16 January 2028 counts full weeks from the start of 2028, 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.
