The solar calendar is only based on the sun, and its representative is the Gregorian calendar. So generally speaking, the solar calendar refers to the Gregorian calendar, and the lunar calendar refers to the calendar based on the moon. Only Islamic countries use the lunar calendar in the world, and the accuracy of the lunar calendar is very low. China and western countries do not use it.
