The History of Islamic Calendar in the light of “Hijrath”

The Hijri year is the year used in the Islamic lunar calendar, beginning its count from 622 CE, the year of the migration of Muhammad and his followers from Makkah to Madina (“Yathrib” in Past), an event known as the “Hijrath” .

The Hijri era is calculated according to the Islamic lunar calendar and not the Julian or Gregorian solar one. It thus does not begin on January 1 CE, but on the first day of the month of Muharram which occurred in 622 CE.
