A lunar calendar consists of 12 months, with each lunar month corresponding to one lunar cycle or the time it takes the moon to orbit the Earth. Unlike the Gregorian calendar, which has 365.24 days in a year, the lunar calendar has approximately 354 days in a year. Therefore, to synchronize the lunar calendar with the solar calendar, which is used in most countries, leap months are added every few years. In some cultures, each lunar month is associated with a specific phase or event, such as a full moon or a harvest festival. The lunar calendar is still widely used in many countries for religious and cultural events.
