The Chinese Calendar tells you about upcoming Chinese new years and converts Chinese and European calendar dates (and also dates in the Archetypes Calendar). It provides exact times of dark moons and solar terms and is thus an indispensible tool for any serious study of the Chinese Calendar.

"The Best Chinese Calendar Software"

Many people try to write a program for the Chinese calendar without first really understanding the astronomical rules. The author of this program has done his homework, and the result is impressive.

Since the Chinese calendar is very complex, and this program does not shy away from the details, it may seem overwhelming to a casual user. But if power, accuracy and reliability are important, this is the program for you.

If you are interested in doing careful analysis of the Chinese calendar, for historical, astronomical or astrological purposes, there is no other alternative.
