Ancient Chinese Birth Chart

Legend says that the original Chinese birth chart was buried in a tomb near Beijing, China for the past 700 years. The original is now displayed in the Beijing Institute of Science. You can determine the lunar calendar's prediction as to whether it's a Boy or Girl by cross-referencing the mother's age at time of conception and the month during which she conceived. If you question the accuracy of the ancient Chinese calendar try a sonogram, but it's not as much fun.
