May is the eleventh month of the financial year that began the previous July, one month out from the 30 June close. 16 May 2027 falls in the second calendar quarter of 2027, with the financial year's EOFY reporting period now clearly in view for most businesses and payroll teams across the country.
Any deadline or bill payment due on Sunday 16 May 2027 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 2027 can show a different total depending on which state's calendar applies to 16 May. Interstate businesses need to check more than one state's list before setting a national deadline.
