Guinea-Bissau public holidays in August 2027

August 2027 in Guinea-Bissau runs 31 calendar days, Northern-hemisphere summer and Southern-hemisphere winter. Guinea-Bissau does not observe any national public holidays in August 2027. Because all August 2027 holidays fall on the weekend (or there are none), every weekday remains a working day. That leaves 22 working days for Guinea-Bissau businesses, payroll cycles, and project schedules in August 2027. August is comparatively quiet in the Christian calendar but includes Assumption of Mary on the 15th in Catholic countries and several civic anniversaries across South America.
