The Chinese Gender Calendar is believed to be over 700 years old. It was found in a Royal Tomb near Peking, China. The chart uses the mother’s lunar age and the lunar month of conception to help predict the gender of an unborn baby. It can also be used when you are trying to conceive a baby of a particular gender. There are anecdotal reports that the Chinese Gender Chart is 90% accurate.

There are many examples of the Chinese Gender Calendar online. However, in order to use the chart, you must know you lunar age at conception. If you were born January 1st up to and including February 20th, then your lunar age is the same as your regular calendar age. If you were born after February 20th, then you add one year to your regular calendar age. You must also remember that the chart is based on the conception month of the child, not the birth month.
