Guinea-Bissau observes one public holiday in September 2026: Independence Day (National Day). One of those — Independence Day (National Day) — falls on a weekday and reduces the working-day count by one. That leaves 21 working days for Guinea-Bissau businesses, payroll cycles, and project schedules in September 2026. September brings Labor Day in the US and Canada (first Monday) and the start of the Jewish High Holy Days in many years.
