Predictor Chino del Sexo del Bebé 2026
Introduce dos fechas y deja que el legendario calendario chino adivine quién está en camino — con conversión lunar real y un planificador divertido.
🍼 Solo diversión — no es una prueba médica
Babies’ sex is set by chromosomes. Only medical tests (NIPT blood test or ultrasound) can confirm it. This site is for entertainment.
How this predictor works (the honest version)
Most "traditional charts" online quietly fudge the two calendar conversions the method depends on. Ours uses the official-range 1900–2100 lunisolar tables: exact Chinese New Year anchors, month sizes and leap months. Here's the flow:
Enter the mother’s birth date
We convert it to the lunar calendar — counts as the traditional age (1 at birth, +1 every Chinese New Year).
Add your conception, due date or LMP
Whatever you know best. We derive the conception moment, then map it to the exact lunar month (leap months included).

Your lunar age × lunar month intersection lights up the prediction — boy or girl, with confetti either way.
Chinese gender prediction, decoded
The Chinese gender predictor — friends call it the Chinese baby calendar, pregnancy chart or Qing Palace chart (清宫图) — matches a mother's lunar age with the lunar month of conception on a fixed grid of boy/girl cells. Predictions don't use Western dates, which is exactly where every calculator earns its keep: a mother born before Chinese New Year, a conception in the tail of a lunar year, or a leap month can each flip the cell.
Three input modes, one instant answer
Know the exact conception date? Use it. Working from the due date? We subtract 266 days. Only remember the first day of your last period? We add 14 days to estimate ovulation. Whichever you choose, the lunar conversion is computed live and displayed beside your result so you can sanity-check the guesschart yourself.
What the result tells you
Every prediction card shows the lunar age the chart used, the precise lunar month (with a leap-month asterisk when relevant), the baby's Chinese zodiac, and the baby's Western sign by estimate — a genuinely personal read of the 700-year legend. It's a beloved tradition, not a test: for real answers, NIPT from ~10 weeks or an anatomy ultrasound at 18–20 weeks.
Predictor FAQ
How accurate is the Chinese gender predictor?
Honestly? About the same as a coin flip — roughly 50%. Claims of 70–93% accuracy circulate online, but controlled studies have found no evidence the chart can predict a baby’s sex. We present it as a beloved tradition, not a medical test, and our tool shows exactly how the lunar dates are converted so you can follow along.
What is the Chinese gender calendar and where does it come from?
It’s a traditional chart said to date back 700 years and to have been discovered in a royal tomb near Beijing, with other versions tracing it to the Qing dynasty (1644–1911). Historians can’t verify these tales, but the chart has circled the globe as a fun pregnancy ritual. It predicts using the mother’s lunar age and lunar month of conception.
Do I need to know my lunar age or lunar dates?
No. Our predictor converts your birth date and conception date into exact lunar dates automatically — using the full Chinese lunisolar calendar tables (1900–2100), so dates near Chinese New Year or leap months are handled correctly.
I’m not sure of my conception date. Can I still use it?
Yes. Switch the second input to “Baby’s due date” (we estimate conception ≈ due date − 266 days) or “Last period started” (conception ≈ LMP + 14 days). Small date shifts can matter near lunar month boundaries, so exact dates will always be most precise.
Does the Chinese gender chart change every year?
No — there’s one authentic chart with the same boy/girl cells every year. What changes is the calendar conversion: Chinese New Year moves (Feb 17, 2026, for example) and lunar months start on different Gregorian dates, so the same Western dates can land in different cells each year.
Why is my lunar age one or two years older than my real age?
Chinese tradition counts you as age 1 at birth (pregnancy time counts), and you gain a year at Chinese New Year rather than on your birthday. So your lunar age is usually your Western age plus one, sometimes plus two — our lunar age calculator works it out instantly.
Can the chart or planner really choose my baby’s sex?
No. A baby’s sex is determined by chromosomes at conception, and no calendar can influence it. Use the planner for fun and for understanding how the chart is read — then leave family planning decisions to you and your healthcare provider.
How can I know my baby’s sex for real?
Medical methods only: the NIPT blood test can indicate fetal sex from about 10 weeks, and the 18–20-week anatomy ultrasound is the classic confirmation moment. Both are dramatically more reliable than any folklore method.
