From Wikipedia, the free encyclopedia. A solar calendar is a calendar whose dates indicate the position of Earth on its revolution around the Sun or, equivalently, the apparent position of the sun moving on the celestial sphere. The other commonly used system is a lunar calendar which dates the months based on cycles of the lunar phases. The Gregorian calendar, widely accepted as standard in the world, is an example of solar calendar.
