10 Facts About Chinese Gender Predictor Charts

4. How the Calendar Works

The gender predictor calculator converts the mother’s date of birth and the date of conception into the lunar equivalent, along with the baby’s gender prediction and Chinese zodiac sign. For example, if the mother is born March 1, 1985, and the date of conception is August 20, 2018, the calculator shows that baby will be a girl, born under the Chinese zodiac sign of the pig. It also shows the mother’s lunar age at conception as 34, even though the 2018 Gregorian calendar considers her to be 33.
