Solar Calendar

A solar calendar is a calendar system based on the Earth's position relative to the sun. It is designed to reflect the length of a tropical year, which is the time it takes for the Earth to complete one orbit around the sun.

The most widely used solar calendar today is the Gregorian calendar, which is the standard calendar in many countries. It is based on a 365-day year, with an extra day added in leap years to account for the slight discrepancy between the calendar year and the tropical year.

Other solar calendars include the Julian calendar, the Egyptian calendar, and the Mayan calendar, each with its own unique way of accounting for the solar year.

Solar calendars are important for agricultural and cultural purposes, as they help people track the seasons and plan activities such as planting and harvesting. They also provide a framework for organizing social and religious events.
