Farvardin 29 is marked in the official calendar of the Islamic Republic as “Army Day.” The designation was introduced in 1979, during the early months following the Islamic Republic Revolution. At that time, a directive issued by Ruhollah Khomeini called on the army to hold military parades and public displays on this date, in order to demonstrate its support for the newly established political system. The decision was made in a period when the future and role of the army were subjects of debate in the post-revolutionary political environment. Declaring an Army Day was intended to reaffirm the continuation of the institution within the framework of the new state. In subsequent years, the date was incorporated into the country’s official calendar as an annual observance. Military parades and related ceremonies are typically held on this day, often attended by political and military officials. According to Islamic Republic sources, this observance is registered and presented in the official calendar in this form and with these descriptions.
