Accuracy & disclaimer

Records suggest the Qing dynasty gender chart was displayed within the Forbidden City. Scholarly reviews have never confirmed predictive power — reported accuracy is anecdotal and varies widely.

This experience is for cultural curiosity only. Gender predictions should always be confirmed by qualified healthcare providers through ultrasound or genetic diagnostics. Mum Choice does not collect or store personal health information for this tool.

How this works

Step 1 — Lunar conversions

We translate both dates into the Chinese lunar calendar using the open-source overtrue/chinese-calendar ephemeris.
Step 2 — Calculate lunar age

Age is counted by lunar years with the traditional +1 rule once the new lunar year begins.
Step 3 — Apply the palace chart

We cross reference the mother's lunar age against the lunar month of conception to output “boy” or “girl”.
Step 4 — Apply the palace chart

We translate both dates into the Chinese lunar calendar using the open-source overtrue/chinese-calendar ephemeris.

Common questions

Is this medically accurate?

No. Studies have never validated the chart. Treat this as cultural folklore and always rely on ultrasound or genetic testing for real answers.

Which dates should I enter?

Use the mother's date of birth and your best estimate of the conception date in the AD calendar.

What if I am outside the age range?

The historic chart only covers lunar ages 18 to 45. We clamp the age into that range so the tool can still respond, but it may be less meaningful.

What makes this tool special?

Enter both dates in the AD calendar then let us handle the lunar conversions automatically.
