April is the tenth month of the financial year that began the previous July, with 5 April 2026 falling two months out from the 30 June close. It also sits in the second calendar quarter of 2026, the quarter that runs from April to June under the standard January-to-December quarter system used on this page.
Any deadline or bill payment due on Sunday 5 April 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 5 April. Interstate businesses need to check more than one state's list before setting a national deadline.
