Tarikh-i-Alfi
Tarikh-i-Alfi is a historical calendar system used to count years based on the Islamic lunar calendar, beginning from the Hijra, the migration of Prophet Muhammad from Mecca to Medina in 622 CE. The term "Alfi" signifies a thousand, referring to a calendar era that marks a thousand years since that migration. This system helps Muslims and historians track Islamic history and events within a chronological framework distinct from the Gregorian calendar. It provides a way to date historical and religious events according to the Islamic lunar year cycle, which is approximately 354 days long.
