How this calculator works
- We calculate your age on the conception date.
- Traditional lunar age adds one year to that age; the folklore chart uses that lunar age.
- Your conception month sets the column in the chart; the row is your lunar age.
Different versions of the chart exist. This one follows a popular public-domain pattern for ages 18-45.

FAQs
Is this Chinese gender predictor accurate?
It is a folklore method with a 50-50 chance. Treat it as a fun guess, not a medical result.
Why do you add one year for lunar age?
Traditional Chinese age reckoning counts a baby as one year old at birth, so we add one to your age at conception to mimic the lunar age used by the chart.
What if I do not know my exact conception date?
Use your best estimate. Conception typically happens about two weeks after the first day of your last period, but cycles vary.
Can I use this for multiple pregnancies?
The chart is built for single pregnancies and does not account for twins or multiples.
