About Baby Gender Predictor

This baby gender planning formula was given to my wife by the old lady, who claimed that it was very popular with Transylvanian/Galician gypsies at the time of Austro-Hungary. Calculations in this formula are in someway tortuous so I decided to create a small program to make it easier to check the legitimacy of this method. After using lots of parent/child birthdays I can assert that, strangely enough, it worked in a disproportionately large amount of cases. We even planned and got our baby-girl using this method.

Is this method really effective? Honestly, I doubt It. But do not mention that to my wife. She is a true believer. After all, we did get the girl! How does it appeared to yield about a 75% success rate!? Pure luck!? Coincidence!? Insufficient number of test cases?

Test it yourself and have fun!
