The anniversary of Islamic revolution is celebrated on 22 Bahman on the Iranian calendar with Iranian marches toward Azadi Tower. This political celebration held on the last day of the celebration called the Ten Days (Dahiye) of Dawn (Fajr). and also I gotta say everyone was super nice to me and let me take pictures of them no matter because as a person who lives in Iran public don't like it at all when you take pictures of them so this was a really great opportunity for me.
