This ancient Chinese birth chart was uncovered in the tomb of a monk in Beijing, according to legend. When archaeologists examined the parchment it was printed on, they found that the chart predicts the sex of your baby with a spooky amount of accuracy.
Just look down the chart to find how old you'll be when you give birth and along the top for the month your baby was conceived. The square where the two meet will show if you're having a boy or a girl.
And if it works for you, let us know!
