Slovenia Feiertage im September 2026

September 2026 in Slovenia runs 30 calendar days, Northern-hemisphere autumn and Southern-hemisphere spring. Slovenia observes 2 public holidays in September 2026: Integration of Primorska into the Homeland, Slovenian Sports Day. 2 of those fall on weekdays and reduce the working-day count accordingly. That leaves 20 working days for Slovenia 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.
