The Chinese gender chart was said to be discovered in a tomb that was over seven centuries old. The chart uses the lunar age (age based on a 29-day month) of the pregnant woman and the month, the child is due to predict the gender of the child. Some people swear by the accuracy of the Chinese gender predictor, which is said to have an over 50/50 accuracy rate but we would recommend that you only use the chart for fun. The actual accuracy rate of anyone guessing the birth of a child is 50/50 since you can only have a boy or a girl but playing with the Chinese gender chart can be fun and entertaining.
There are other ways to help predict the sex of a child along with the Chinese gender predictor such as using a fortune-teller or using an ultrasound test. Ultrasounds are also not completely accurate all the time, so maybe we should spend more time focused on the pregnancy and the joy of having a baby and enjoy the surprise that will be offered to us in nine months. Nature intended the sex to be a mystery up until birth or it would have given us ways to tell what the sex of the baby will be before the birth of the child.
