The Qing Dynasty Legend

Discovered in an ancient royal tomb near Beijing over 700 years ago, the original Chinese Gender Chart was allegedly used by imperial concubines to ensure the birth of male heirs. Today, our Chinese Gender Predictor digitizes this ancient matrix to provide expectant mothers with an entertaining glimpse into their baby's future.

The Rule of Lunar Age

The biggest mistake Western users make when reading manual Chinese gender charts is using their standard biological age. The ancient chart strictly requires the mother's Lunar Age. Because the Chinese Lunar Calendar factors in the ~9 months spent in the womb, your Lunar Age is generally one to two years older than your Western age. Our calculator runs this conversion automatically behind the scenes.

Chart Intersections

The prediction relies on plotting two specific coordinates on the ancient grid:

  • The mother's exact Lunar Age at the time of conception.
  • The specific Lunar Month in which conception occurred.

Medical Disclaimer: This tool is digitized folklore. The Chinese Gender Chart has an exact scientific accuracy rate of 50%. It should be used strictly for entertainment purposes and never as a replacement for clinical ultrasound or NIPT blood testing.

Frequently Asked Questions

Is the Chinese Gender Chart accurate?

Statistically, it is exactly 50% accurate (essentially a coin flip). While millions of mothers swear by its results, there is no scientific basis linking a mother's lunar age to the Y-chromosome of the father's sperm.

Why do I have to use Lunar Age?

The chart was created in ancient China, which operated exclusively on the Lunar Calendar. Without converting your Western Gregorian age to the corresponding Chinese Lunar Age, you are plotting the wrong coordinates on the chart.

What if I don't know my exact conception date?

If you don't know the exact date, use the approximate week. However, if your conception happened right on the cusp of a month change, the chart's prediction might flip depending on which month you select.
