The Chinese Gender Calendar was supposedly discovered by a Chinese Scientist who drew this chart which was buried in a Royal tomb about 700 years ago. Most of the Gender Calendars you find on the web tell you that it is based off the mother's lunar age, but do not tell you how to go about calculating it.
The first method below being used with the permission of the website owner. The Baby Gender Predictor is based off the Chinese Lunar Calendar, and actually does the calculations to convert the mother's age to the proper format.
The second tool below, is the one you will find all over the web. It gives no way to convert your age into your chinese lunar age, on which this tool was based, so we would expect that the results would be correct about 50% of the time, basically as scientific as flipping a coin.
We are conducting a little experiment here. Check the accuracy of the methods below for each of your children and then let us know if the results were correct by taking part in our poll for each of our methods below. If there is a bit of truth to the Chinese Lunar Calendar, we would expect for the first tool to have a higher percentage of correct predictions.
