The Hijri Calendar traces its roots back to the era of Prophet Muhammad (PBUH), who introduced it as an alternative to the lunar-based calendars practiced in pre-Islamic Arabia. This revolutionary change marked a significant shift in how Muslim societies organized their time and celebrated important events.

This unique feature sets it apart from the more widely used solar calendars, such as the Gregorian. Over time, the Hijri Calendar became integral to Muslim life, used for religious observances like Ramadan and Hajj, and even in daily routines like calculating holidays and dates of birth.
