Iran Feiertage im August 2026

August 2026 in Iran runs 31 calendar days, Northern-hemisphere summer and Southern-hemisphere winter. Iran observes one public holiday in August 2026: Eid al-Ghadeer. One of those — Eid al-Ghadeer — falls on a weekday and reduces the working-day count by one. That leaves 20 working days for Iran businesses, payroll cycles, and project schedules in August 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.
