📖 Understanding Gender Prediction Methods
Chinese Gender Chart
Found in a Qing dynasty royal tomb over 700 years ago, this chart relies on the mother's lunar age at conception and the lunar month of conception.
Mayan Gender Calendar
The ancient Mayans calculated baby gender by looking at the mother's age and the year of conception. If both are even or odd, it's a girl; if mixed, it's a boy!

❓ Frequently Asked Questions
How accurate is the Chinese Gender Predictor?
Scientifically, the Chinese Gender Predictor has an accuracy rate of about 50%—roughly the same as flipping a coin. It is a fun cultural tradition rather than a medical tool.
What is Lunar Age vs. Gregorian Age?
In traditional Chinese culture, a baby is considered 1 year old at birth, and gains a year at each Chinese New Year. In practice, adding 1 year to your current age gives a close approximation of your lunar age.
When is the earliest medical test for baby gender?
A Non-Invasive Prenatal Test (NIPT) blood test can detect cell-free fetal DNA as early as 10 weeks into pregnancy with over 99% accuracy.
Does timing of conception affect gender?
According to the Shettles method folklore, Y-sperm (boy) swim faster but die sooner, while X-sperm (girl) live longer. However, modern clinical research shows no statistically significant impact on birth ratio.
