2026 has 365 days, and January opens the year with the tropical north deep in its wet season, part of the cyclone season that runs from November through to April. In the southern states, 19 January 2026 sits in the driest, hottest stretch of the year, when bushfire warnings are issued most frequently across Victoria, South Australia, Tasmania and inland New South Wales.
Monday 19 January 2026 is the first working day of its week. Any bill, deadline or rostered task set for the preceding Saturday or Sunday moves to this date under standard business-day rules, and the working-day count above treats it as day one of a fresh five-day working stretch that runs through to Friday, before the weekend resets the cycle again.
2026 has 365 days on the calendar. Leap years add a single extra day to February, giving those years 366 days instead of 365 and shifting the day-of-year number for every date from March onward by one compared with an ordinary year. This is the only irregularity in the length of the Australian calendar year.
