Frequently Asked Questions
Everything you need to know about our Chinese Gender Predictor and the lunar chart calculation it uses.
No. Enter the regular birth date and conception date, and the calculator handles the lunar conversion for you automatically.
No. This is a traditional folklore predictor for entertainment only. A baby's biological sex can only be confirmed through medical methods.
The traditional chart is based on the mother's lunar age at conception and the lunar month of conception, so the page shows those converted values for transparency.
The result will tell you when the conception date falls in a leap lunar month. For chart lookup, the tool uses the underlying month number that matches the traditional month slot.
The chart used here covers lunar ages 18 through 45. If the converted lunar age at conception falls outside that range, the predictor returns an error instead of guessing.
