Frequently Asked Questions
Is the Chinese gender chart accurate?
Studies show it is about 50% accurate — the same as random chance. It has no scientific basis for predicting gender.
Where did this chart come from?
Legend says it was found in a royal tomb near Beijing over 700 years ago. Its actual origin is debated by historians.
What determines a baby's actual gender?
Gender is determined by the sperm cell that fertilizes the egg. If it carries an X chromosome, the baby is female (XX). If Y, the baby is male (XY).
When can I find out the real gender?
Ultrasound can typically determine gender at 18-20 weeks. Non-invasive prenatal testing (NIPT) blood tests can determine gender as early as 10 weeks.
Should I use lunar or Western age?
Traditionally, the chart uses Chinese lunar age (add 1 year to Western age). This calculator uses the simplified Western age version.
