Will it be a boy or a girl? Try the ancient Chinese gender chart — enter your age at conception and the conception month to find out!
For entertainment purposes only. Not scientifically validated.
The Chinese gender predictor is based on an ancient chart and is for entertainment purposes only. Studies have found it to be about 50% accurate — essentially a coin toss. A paid ultrasound report is also for fun: a written reading using Ramzi, Nub, or Skull theory, not a medical test.
The chart cross-references the mother's age at conception with the month of conception. According to legend, it was found in a royal tomb near Beijing and is said to be over 700 years old.
No method short of a medical test is reliable. Our paid reading uses popular theories like Ramzi theory (placenta position), Nub theory (nub angle at 12 weeks), and Skull theory (cranial features) on your actual ultrasound image. They are not scientifically proven, so it is for fun, not medical.

The Chinese gender predictor is one of the most popular baby gender prediction tools in the world. Based on an ancient chart said to be over 700 years old, it was allegedly discovered in a royal tomb near Beijing. The chart cross-references the mother's age at conception with the month of conception to predict whether you're having a boy or a girl.
While the Chinese gender chart is fun and culturally fascinating, studies have found it to be approximately 50% accurate — essentially a coin flip. For a confirmed answer, ask your doctor about NIPT or the anatomy scan.
Tip: Use your lunar age to be traditional, or your regular age for simplicity. Our calculator uses standard (Gregorian) age.
