Thailandの公的祝日 8月 2026

8月 2026 in Thailand runs 31 calendar days, Northern-hemisphere summer and Southern-hemisphere winter. Thailand observes one public holiday in 8月 2026: The Queen Mother's Birthday. One of those — The Queen Mother's Birthday — falls on a weekday and reduces the working-day count by one. That leaves 20 working days for Thailand businesses, payroll cycles, and project schedules in 8月 2026. 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.
