Chinese Lunar Calendar Conversion  

Many people are looking for the formula to convert from the Gregorian Calendar to Chinese Lunar Calendar. According to my research from 1988 to 1992, there is no formula for the Chinese Lunar Calendar Conversion to satisfy me. Because the motion and rotation of moon are uneven, unstable and wobbling, it's very hard to have a accurate formula for Chinese Lunar Calendar over any century.

Any straight-forward formula available today only give us a low-precision result. Without a high-precision astronomical data, the assignments of Chinese Lunar Leap Month (a.k.a. Intercalary Month) will become a great chaos.

The following Chinese Lunar Calendar conversion uses high-precision astronomical data to do the calculation. It is the most accurate method to convert Chinese Lunar Calendar. We use for calculating the Chinese age.
