22 Bahman rallies in Tehran

Every year, Iranians mark the anniversary of their Islamic Revolution from February 1 to 11, known as the Ten-Day Fajr (Dawn) ceremonies.

Each year on the 22nd day of the month of Bahman on the Persian calendar (11th of February), Iranians turn out in ceremonies attended by high-ranking officials to renew their allegiance to the Islamic establishment and Imam Khomeini, the late founder of the Islamic Republic.
