Baby Gender Calendar Predictor

Use this calendar to explore how the gender formula might work for your future child planning. Just enter the birthdays of both parents and we'll generate a 5-year conception calendar showing predictions for each month.

If you're curious how accurate this method might be, you can also test it here using conception dates of your own children, relatives, or friends. Who knows — maybe we're on to something, or maybe it's just a glorified coin toss!
