Air Force Day, Bahman 19. This day commemorates the Iranian Air Force and is observed annually in the official calendar. On Bahman 19, 1357, a group of Air Force personnel visited Ruhollah Khomeini’s residence and declared their support for the Islamic Revolution. This event played a significant role in the final days of the Pahlavi regime and is considered a turning point in Iran’s contemporary history. In 1358, Bahman 19 was officially designated as Air Force Day and added to the calendar by authorities, in recognition of the event’s importance in the victory of the revolution and to honor the Air Force’s impact on the political and military developments of that period. Today, various ceremonies are held to honor the contributions and role of the Air Force, serving as a reminder of its importance in national defense and security, and as an opportunity to recognize the service and sacrifices of its members. According to Islamic Republic sources, this observance is registered and presented in the official calendar in this form and with these descriptions.
