United States — October 2027

United States businesses have 20 working days in October 2027 — that's 31 calendar days minus 10 weekend days and 1 weekday public holiday (Indigenous Peoples' Day). Northern-hemisphere autumn and Southern-hemisphere spring typically governs the work-rhythm in October; project deadlines and payroll cycles in United States should account for the holiday days listed above. October hosts Indigenous Peoples' Day / Columbus Day in the Americas on the second Monday and Reformation Day in northern-European Protestant traditions on the 31st. For pay-period planning, October 2027 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 United States payroll-period calculations.
