Traditional Chinese lunar-calendar guess

This uses the classic Chinese gender chart, which cross-references the mother's age with the conception month. It has no scientific basis.

This free gender predictor guesses whether a baby will be a boy or a girl using the traditional Chinese lunar calendar method. Enter the mother's age at conception and the month the baby was conceived, and the tool reads the answer from the classic Chinese gender chart. Everything runs in your browser and nothing is stored.
