Baby Gender Predictor
Discover your baby’s predicted gender with the ancient Chinese Gender Chart. Enter your age and conception month for a quick, just-for-fun result.
How it works
The Chinese Gender Calendar compares your lunar age at conception with the month you conceived.
How does the predictor work?
The Chinese Gender Calendar compares your age at conception with the month you conceived. The original chart uses lunar age, so the calculator adjusts that step for you.
If you are not sure when you conceived, our due date calculator can help you estimate the dates.
A final note
This tool is for fun only. JustParents does not support or encourage gender selection, and it should never be used to try to influence whether you have a boy or a girl.
Every baby is valued and welcomed, whatever the result.
Frequently asked questions
What is the Chinese Gender Calendar?
It is a centuries-old chart said to have been discovered in a royal tomb in China more than 700 years ago. It claims to predict a baby’s sex from the mother’s age and month of conception.
Whether it is surprisingly accurate or simply a bit of fun is still up for debate, which is part of the appeal.
How do I calculate my lunar age?
You do not need to work it out yourself. The original chart uses lunar age, which is usually your actual age plus 2 years, and our predictor adjusts it automatically when you enter your age.
Does it work for all ages?
Our updated predictor works for expectant mothers aged 16 to 44. That includes ages 16 and 17, which many Chinese gender predictors do not support.
Is this tool accurate?
This tool is just for fun. While the Chinese Gender Calendar has been shared for generations, it is not scientifically proven to predict your baby’s sex.
If you are eager to know your baby’s sex, an ultrasound scan later in pregnancy will give you a much more reliable answer.
