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. 17 January 2029 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 landing on a Wednesday sits in the middle of its working week rather than beside a weekend, so it does not create a long weekend on its own. Wednesday 17 January 2029 falls on this day of the week, at the working week's midpoint, three working days deep into the week.
The quarter containing 17 January 2029 is based on the calendar year running January to December, a separate system from the Australian financial year, which runs from 1 July to 30 June and splits into its own four quarters. Businesses often track both systems side by side, one for tax filings and one for calendar-year planning.
