Iran public holidays in October 2027

October 2027 in Iran runs 31 calendar days, Northern-hemisphere autumn and Southern-hemisphere spring. Iran does not observe any national public holidays in October 2027. Because all October 2027 holidays fall on the weekend (or there are none), every weekday remains a working day. That leaves 21 working days for Iran businesses, payroll cycles, and project schedules in October 2027. October hosts Indigenous Peoples' Day / Columbus Day in the Americas on the second Monday and Reformation Day in northern-European Protestant traditions on the 31st.
