Solar Calendar

A solar calendar is a calendar system based on the movement of the Earth around the sun. It is designed to keep track of the solar year, which is the time it takes for the Earth to complete one orbit around the sun. Solar calendars are widely used around the world to track the seasons and plan agricultural activities, religious observances, and civil events.
