What is Lunar Calendar?
A lunar calendar is actually a calendar whose date indicates the moon phase. A lunar month is determined by the period required for the moon to complete its full phasic cycle of 29 and a half days, a standard that makes the lunar year a full 11 days shorter than its solar counterpart. This difference is made up every 19 years by the addition of seven lunar months, which is called leap month. How to convert Gregorian (Western) Calendar to Chinese Lunar Calendar?
