Boy or girl: what folklore says

Old wives’ tales have been guessing baby gender for centuries. The Chinese gender chart is the most enduring of them: a grid that pairs maternal lunar age with the lunar month of conception. Other folk methods include carrying-high vs carrying-low, ring-over-bump pendulum tests, food cravings, the Mayan calendar, and the heart-rate myth.

The honest answer about all of them: they’re about 50% accurate. Which is why they’re so popular — they make for a fun group game where everyone gets to guess and someone is inevitably right.

When you want a real answer

  • NIPT blood test from ~10 weeks — >99% accurate. Often the earliest reliable answer.
  • Anatomy ultrasound at 18–22 weeks — 95–99% accurate, depending on baby’s position.
  • Pre-implantation genetic testing (PGT) — used in some IVF cycles. Sex is known before transfer.

Speak with your healthcare provider about what makes sense for your pregnancy. Some providers will tell you the sex at the anatomy scan; others wait until you ask.

Frequently asked questions

How does the Baby Gender Predictor work?
We use the Chinese gender chart — a folk tradition that pairs the mother’s lunar age at conception with the lunar month of conception to predict a boy or girl. It’s a 50/50 guess in practice; treat it as fun, not as a medical answer.
When can I find out my baby’s actual sex?
Non-invasive prenatal testing (NIPT) can determine fetal sex with >99% accuracy from around 10 weeks of pregnancy via a maternal blood sample. The 18–22 week anatomy ultrasound also reveals sex with high accuracy when the baby is in a cooperative position.
Old wives’ tales — any of them actually work?
No. Carrying high or low, food cravings, the ring-over-bump test, the Mayan calendar, the baking-soda urine test, the heart-rate myth — none of these have stood up to research. They’re fun guesses, no better than chance.
Can the Chinese chart predict twins?
No. The chart only predicts one gender outcome per conception event. For twin pregnancies, only ultrasound and DNA testing can reveal each baby’s sex.
Does the chart account for IVF or fertility treatment?
No. The Chinese chart is folklore based on lunar age and month — it makes no distinction between natural conception, IVF, or any other method. If your provider has performed pre-implantation genetic testing (PGT), they may already know the embryo’s sex.
