South Korea — 2027年九月

South Korea businesses have 19 working days in 九月 2027 — that's 30 calendar days minus 8 weekend days and 3 weekday public holidays (Chuseok, Chuseok, Chuseok). Northern-hemisphere autumn and Southern-hemisphere spring typically governs the work-rhythm in 九月; project deadlines and payroll cycles in South Korea should account for the holiday days listed above. September brings Labor Day in the US and Canada (first Monday) and the start of the Jewish High Holy Days in many years. For pay-period planning, 九月 2027 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.
