Islamic Calendar (Undated)

The Islamic calendar, also known as the Hijri calendar, is a lunar calendar based on the cycles of the moon. It consists of 12 lunar months, each approximately 29 or 30 days long, resulting in a year of about 354 days. The Islamic calendar is used to determine the dates of religious events and observances in Islam, and it is distinct from the Gregorian calendar, which is based on the solar cycle.
