👶 Chinese Baby Gender Predictor Calendar

The traditional Chinese gender prediction chart uses the mother's lunar age at conception and the lunar month of conception to mark “boy” or “girl” in a 2D calendar. This calculator uses a simplified method:

• We estimate lunar age as conception year − birth year + 1 (a common rule of thumb).
• We use a widely shared modern version of the gender chart to decide “boy” or “girl”.

It’s important to remember that this is not scientifically validated and should be used for fun only. Ultrasound and genetic tests are the only reliable ways to know your baby’s sex before birth.
