The Official Language, Script, Calendar, and Flag of the Country
The official language and script of Iran, the lingua franca of its
people, is Persian. Official documents, correspondence, and texts,
as well as text-books, must be in this language and script. However,
the use of regional and tribal languages in the press and mass
media, as well as for teaching of their literature in schools, is
allowed in addition to Persian.
Since the language of the Qur'an and Islamic texts and teachings is
Arabic, and since Persian literature is thoroughly permeated by this
language, it must be taught after elementary level, in all classes
of secondary school and in all areas of study.
The official calendar of the country takes as its point of departure
the migration of the Prophet of Islam - God's peace and blessings
upon him and his Family. Both the solar and lunar Islamic calendars
are recognized, but government offices will function according to
the solar calendar. The official weekly holiday is Friday.
The official flag of Iran is composed of green, white and red colors
with the special emblem of the Islamic Republic, together with the
motto [Allah-o Akbar].
