Australiaの公的祝日 9月 2026

9月 2026 in Australia runs 30 calendar days, Northern-hemisphere autumn and Southern-hemisphere spring. Australia observes one public holiday in 9月 2026: King's Birthday. One of those — King's Birthday — falls on a weekday and reduces the working-day count by one. That leaves 21 working days for Australia businesses, payroll cycles, and project schedules in 9月 2026. September brings Labor Day in the US and Canada (first Monday) and the start of the Jewish High Holy Days in many years.
