South Korea — May 2026

South Korea businesses have 19 working days in May 2026 — that's 31 calendar days minus 10 weekend days and 2 weekday public holidays (Children's Day, Day off for Buddha's Birthday). Northern-hemisphere spring and Southern-hemisphere autumn typically governs the work-rhythm in May; project deadlines and payroll cycles in South Korea 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 3 full work-weeks plus 4 additional weekdays, 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. Use this figure as the authoritative baseline for South Korea payroll-period calculations.
