How It Works
This traditional Chinese method uses the mother's lunar age and the lunar month of conception to make a boy-or-girl prediction.
Mother's lunar age
The engine converts the birth date and conception date to lunar years, then uses traditional nominal age at conception.
Lunar conception month
The conception date is converted to its lunar month, including whether that month is a leap month.
About this tradition
The Chinese Gender Predictor is a traditional folklore chart that links a mother's lunar age with the lunar month of conception. In this version, both dates are converted with a deterministic lunar calendar engine before the traditional chart is consulted. Some families enjoy it as a light cultural ritual, but it is not scientifically validated and should not be treated as medical information. Use it for entertainment and cultural exploration, then speak with a qualified healthcare professional for medical questions about fetal sex.
Just for fun & cultural exploration
The Chinese Gender Calendar is a traditional folk belief and is not a medical method for determining a baby's sex.
For medical information about fetal sex, consult a qualified healthcare professional.
