Chinese Fertility Calendar - Gender Prediction

 
The Chinese Fertility Calendar is said to predict the gender of your child based on the mothers age at time of conception and month conceived in.
 
It is rumored to be found in a royal tomb in China over 700 years ago.
 
Many couples use it as a way of trying to either increase their chances of having either a boy or a girl, or just for fun to see what you might have depending when you fell pregnant.
 
Just find your age at the time of conception on the left and the month you conceived in at the top to find out whether the Chinese Fertililty Calendar predicts you will be having a boy or a girl.
