What is the difference between a lunar calender and a solar calender

The difference between the lunar calendar and the solar calendar is the celestial body used to measure the passage of time.

Explanation:

The lunar calendar uses the phases of the moon to measure time, usually measuring the time from new moon to new moon as one month. The time required for the Earth to rotate around the Sun is one solar year. The solar calendar typically measures the time between vernal equinoxes.
