Northern-hemisphere autumn and Southern-hemisphere spring typically governs the work-rhythm in Octubre; project deadlines and payroll cycles in South Korea 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, Octubre 2026 contains 4 full work-weeks plus 0 additional weekdays, useful when scheduling milestones or quarterly reviews.
