History of Islamic Calendar

The Islamic calendar has been in use since 622 CE. It came into existence when the Muslim Prophet Muhammad moved to Medina. This event was known as Hijrah, for that reason, it is also known as a  Hijri calendar.

Christian calendar uses AD (Anno Domini) to design their calendar, as the same Islamic calendar uses AH or Hijrah which is a Latin term stands for Anno Hegirae. 

The Persian and Islamic both the calendar began in 622 CE. It would not be wrong if we say both the calendar systems are otherwise underrated. Currently, most people use the Gregorian calendar which is based on the solar calendar but the Islamic calendar is a lunar calendar that follows the movement of the Moon that’s why their year count differs substantially.  For example, according to the Islamic calendar January 1st, 2020 will be the year 1441 AH  which corresponds to the year 1398 in the Hijri calendar.
