Question 1

How does the Chinese Gender Predictor work?

Accepted Answer

The Chinese Gender Predictor is based on the Qing Dynasty Palace Chart (清宫图), an ancient document reportedly discovered in a royal tomb near Beijing. It uses two key inputs — the mother's lunar age at conception and the lunar month of conception — to predict the baby's gender. Both values are calculated using the traditional Chinese Lunar Calendar, not the Gregorian calendar.

Question 2

How accurate is the Chinese Gender Chart?

Accepted Answer

The Chinese Gender Chart is a traditional folk method and has not been scientifically validated. Studies suggest its accuracy is approximately 50%, similar to random chance. It is widely used for entertainment and cultural tradition rather than medical prediction. Always consult a healthcare provider for medical advice.

Question 3

What is the mother's lunar age?

Accepted Answer

Lunar age (虚岁) is the traditional Chinese method of counting age. A baby is considered 1 year old at birth, and gains one year at each Chinese New Year (Lunar New Year), regardless of the actual birthday. This means your lunar age is typically 1–2 years older than your Western age.

Question 4

What if I don't know the exact conception date?

Accepted Answer

If you don't know the exact conception date, you can use the 'Last Menstrual Period (LMP)' option. Enter the first day of your last period, and the calculator will automatically add 14 days to estimate the conception date, which is a standard medical estimation method.
