February is the only month whose length changes from year to year, running to 28 days in an ordinary year and 29 in a leap year. 2026 gives February 28 days, and 15 February 2026 falls inside that count, seven months into the financial year that began the previous July and within the first two months of the 365-day calendar year.
Any deadline or bill payment due on Sunday 15 February 2026 moves to the following Monday under standard business-day rules, since Sunday sits outside the working week this page counts by default. This convention applies consistently across contracts, invoices and statutory deadlines throughout Australia, regardless of which state or territory is involved.
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 15 February. Interstate businesses need to check more than one state's list before setting a national deadline.
