Japan Feiertage im August 2027

August 2027 in Japan runs 31 calendar days, Northern-hemisphere summer and Southern-hemisphere winter. Japan observes one public holiday in August 2027: Mountain Day. One of those — Mountain Day — falls on a weekday and reduces the working-day count by one. That leaves 21 working days for Japan 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.
