The Chinese Gender Prediction Chart (or Chinese Birth Calendar) is an ancient folk method that claims to predict a baby's gender based on the mother's lunar age at conception and the lunar month of conception. However, there is no scientific evidence supporting its accuracy.
How to Use the Chinese Gender Chart (For a Girl): Find the mother’s lunar age at conception:
Your lunar age = current year - birth year +1 (because in Chinese tradition, you’re born at age 1).
Example: If you were born in 1990 and conceived in 2025, your lunar age is 2025 - 1990 + 1 = 36.
Determine the lunar month of conception:
The Chinese calendar differs from the Gregorian calendar.
Example: If conception was in June 2025, check a lunar calendar converter—June might align with the 5th lunar month.
Check the chart:
Find the intersection of the mother’s lunar age (vertical) and lunar month (horizontal).
If the chart shows "Girl", that’s the suggested outcome.
Timing Intercourse for a Girl (Non-Scientific Folk Beliefs): Some traditions suggest conceiving 2-3 days before ovulation (based on the idea that female sperm live longer but are slower).
Others recommend avoiding deep penetration (myth: keeps sperm farther from the cervix, favoring girl-conceiving sperm).
Important Notes: ❌ No proven method guarantees a baby’s gender—even IVF with sex selection isn’t 100%. ✅ The best approach is to focus on healthy conception (track ovulation, prenatal vitamins, etc.).
