The Chinese Gender Calendar is an ancient Chinese secret. This chart can be used to predict the sex of your unborn child. It was supposedly discovered by a Chinese Scientist who drew this chart which was buried in a Royal tomb about 700 years ago. To predict what sex your baby will be, locate the age the mother will be when she gives birth and the month the child was conceived.You can also go to our INTERACTIVE CHINESE GENDER CALENDAR
The Chinese gender sex birth calendar calculator uses the same information as the Chinese gender chart to predict the sex of the unborn child. The only difference is the Chinese gender sex birth calendar calculator is a simple way to find out the babies sex without having to jot down facts, figures and numbers. The Chinese gender sex birth calendar calculator takes the date of conception (month only) and the age of the mother to predict the baby’s sex.
