Legend states that this chart was buried in a tomb near Beijing for nearly 700 years and the original is now in the Beijing Institute of Science. To determine the sex of a child, cross the month the child was conceived with the age of the mother at the time of conception. This chart has been proven to be 93% accurate (many have claimed it is only accurate if you use the date of LMP vs actual conception date).
