Have fun choosing your baby's gender but remember that this Gender Prediction calculator is provided for entertainment purposes only, and I make no claims as to its accuracy. It's just for fun. But amusingly enough, it works!?

Either plan new pregnancy or check the accuracy of this formula by using conception month of your existing kids. Note that sometimes formula cannot convincingly determine the gender of a baby.

You may find more convenient a Calendar view for this baby gender predictor. It has 4-Year Calendar showing which months will give you better chances of conceiving a boy or a girl.

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 after all, we did get the girl! How does it appear to yield about a 75% success rate!? Pure luck or coincidence!? Or something is really behind it!

Test it yourself and have fun!
