What is the difference between the Hijri calendar, the solar calendar, and the Hijri lunar calendar?

The lunar calendar relies on lunar months, forming the basis of the Hijri calendar and determining the times for acts of worship and religious seasons. Allah willed that it not be tied to the seasons of the year, so that the times of worship would vary. As for the solar calendar, it relies on solar months, is fixed with the seasons of the year, and exceeds the lunar calendar by approximately eleven days each year.
