B = boy, G = girl. This is the version cross-checked against two independently published copies of the chart; a few cells differ between publishers' versions, which is worth knowing before you argue about a result with a friend's app.

How the chart is read

The chart has two axes: the mother's lunar age at conception (18 to 45, counted the traditional Chinese way — you're 1 at birth and gain a year each Lunar New Year) and the lunar month of conception (1 to 12). Find the row and column, and the cell says boy or girl.

The catch is that both numbers come from the lunar calendar, not the one on your phone. A conception date in late January can already be lunar month 12 of the previous lunar year, and someone born in January is often two lunar years older than their Western age suggests. This is why two apps can disagree: they disagree about the conversion, not just the chart.

Our converter is a port of a widely used open-source lunar calendar library and is verified against known facts — every Chinese New Year date from 2020 to 2030, and the leap months of 2020, 2023, 2025, and 2028.

Is it accurate?

No. It's a beautiful piece of folk history and roughly as predictive as a coin flip. If you want a real answer, the reliable routes are NIPT screening (a blood test from about 10 weeks) or the 20-week anatomy scan. Use the chart the way it was always meant to be used: as a party trick while you wait.

One more honest note: the chart's origin story — a stone tablet found in a Qing tomb — is itself unverifiable. And as the FAQ above explains, different publishers print slightly different versions of the grid.

FAQ

Frequently Asked Questions

How accurate is the Chinese gender chart?

About as accurate as a coin flip. It's a lunar table that's roughly 300 years old, and no study has shown it predicts anything. It's a fun pre-20-week-scan tradition — nothing more.

What is lunar age (xusui)?

The traditional Chinese way of counting age: you're 1 at birth and gain a year at each Lunar New Year. So your lunar age is usually 1–2 years higher than your Western age. Our calculator computes it from the lunar calendar automatically.

What if I conceived during a leap month?

The chart doesn't have separate columns for leap months. The common convention — and the one we use — is to read the leap month as its base month number (leap month 6 counts as month 6). Your result card tells you when this applies.

Why does my friend's app give a different answer for the same dates?

Because publishers' copies of the chart differ in a few cells. We cross-checked two independently published full copies when building this page (they matched on 22 of 22 overlapping rows), but an English-language copy we compared differed in about a third of rows. Same dates, different edition, different answer.

Where does the chart come from?

The story says a copy was found in a Qing dynasty tomb and later lodged in an institute in Beijing, which is why it's also called the Qing dynasty table (qinggong biao). There's no evidence for the legend — which is part of the fun.

Chart data on this page was transcribed from published copies of the Chinese gender chart (cross-checked between two sources; see our note under the table). Lunar conversion runs locally in your browser — the dates you type never leave your device. Privacy policy · AI Baby Generator
