United States Feiertage im September 2026

September 2026 in United States runs 30 calendar days, Northern-hemisphere autumn and Southern-hemisphere spring. United States observes one public holiday in September 2026: Labor Day. One of those — Labor Day — falls on a weekday and reduces the working-day count by one. That leaves 21 working days for United States 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.
