Anniversary of the Iranian Revolution

The Anniversary of the Islamic Revolution (Persian: راهپیمایی ۲۲ بهمن) is a date celebrated in Iran on 22 Bahman, the 11th month in the Iranian calendar, equivalent to 11 February in the Gregorian calendar.

It commemorates the culmination of the protests that led to the downfall of the Pahlavi dynasty and the establishment of a revolutionary state. The anniversary is held on the last day of the Fajr decade, a ten-day celebration of Ruhollah Khomeini's return to Iran.
