Switzerland — September 2026

Switzerland businesses have 20 working days in September 2026 — that's 30 calendar days minus 8 weekend days and 2 weekday public holidays (Geneva Prayday, Federal Fast Monday). Northern-hemisphere autumn and Southern-hemisphere spring typically governs the work-rhythm in September; project deadlines and payroll cycles in Switzerland 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, September 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 Switzerland payroll-period calculations.
