The Islamic Hijri calendar is a purely lunar calendar based on the cycles of the moon. A lunar year consists of 12 lunar months totaling approximately 354 days which is about 11 days shorter than the solar year. This is why Islamic events like Ramadan and Hajj occur at different times each solar year.
