According to the ancient Chinese Gender Chart based on your lunar age and conception month.
The Chinese Gender Predictor is a fun tradition based on the Chinese Gender Chart — said to be over 700 years old and discovered in a royal tomb near Beijing. It predicts your baby's sex using just two pieces of information: the mother's lunar age at conception and the lunar month of conception.
While it's purely for entertainment, millions of expecting parents try it every year as a fun way to guess, celebrate, and share their pregnancy journey before their 20-week ultrasound.
The original chart cross-references the mother's age with the month she conceived to give a "boy" or "girl" prediction. Our calculator does the hard part for you by:
