Papua New Guinea businesses have 21 working days in May 2026 — that's 31 calendar days minus 10 weekend days and 0 weekday public holidays. Northern-hemisphere spring and Southern-hemisphere autumn typically governs the work-rhythm in May; project deadlines and payroll cycles in Papua New Guinea should account for the holiday days listed above. May centres on May Day / Labour Day, observed in over 80 countries on the 1st, and on Memorial Day in the United States at the end of the month. For pay-period planning, May 2026 contains 4 full work-weeks plus 1 additional weekday, useful when scheduling milestones or quarterly reviews. The working-day count above counts substitute days as a single deduction — it does not double-count when a public holiday falling on a weekend is moved to a Monday or Friday.
