South Korea businesses have 20 working days in August 2026 — that's 31 calendar days minus 10 weekend days and 1 weekday public holiday (Day off for Liberation Day). Northern-hemisphere summer and Southern-hemisphere winter typically governs the work-rhythm in August; project deadlines and payroll cycles in South Korea should account for the holiday days listed above. August is comparatively quiet in the Christian calendar but includes Assumption of Mary on the 15th in Catholic countries and several civic anniversaries across South America. For pay-period planning, August 2026 contains 4 full work-weeks plus 0 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.
