User:Parsika/Imperial chronology

The Imperial Calendar was announced as the official calendar of Iran on 14 March 1976 following the joint meeting of the National Council and the Senate. Until then, the solar Hijri calendar was the official calendar of the country. In this resolution, the origin of the solar calendar was changed from the migration of the Prophet of Islam to the date of the coronation of Cyrus the Great. Based on this chronology, the 1st year of Shahshahi is equal to 559 B.C. And the year 2500 Shahshahi coincides with 1320 solar hijri (the beginning of the reign of Muhammad Reza Pahlavi).
