About Shahanshahi Calendar
What is the Shahanshahi Calendar?
The Shahanshahi (Imperial) calendar is the authentic Persian calendar that begins from Cyrus the Great's coronation in 559 BC. Today is year 2584 Shahanshahi, not year 1404 Shamsi.
Why Shahanshahi?
The Shamsi calendar used in Iran today begins from the Islamic Hijra, ignoring 1180 years of Iranian history. The Shahanshahi calendar honors all 2,584 years of Persian civilization.
