As legend would have it, the Chinese Gender Chart was buried in a royal tomb over 700 years ago. Recently discovered, the chart has been used to predict the gender of an unborn child based on the mother's age and month of conception.

Simply find the age of the mother at the time of conception on the chart below and then follow across to the month the baby was conceived to find the predicted gender. Although this chart is said to have a success rate of over 90 percent, keep in mind that this is solely for entertainment purposes. Enjoy!
