How to use the Chinese Gender Predictor ?

Back in ancient China, many people used a lengendary Gender Chart to predict and select baby’s gender. According to the legend, the Chinese Gender Calendar was buried in the royal tomb of an imperial family and was discovered more than 700 years ago. The calcultation to know if the the baby is a boy or a girl are said to be based on traditionnal Chinese beliefs like Yin-Yang, Five Elements, Eight Diagrams and time.

The chinese calendar predictor method use two values: the "Lunar age" of the mother when she got pregnant and the Chinese Lunar Month of conception. When you have these two values, all you need to do is to compute the formula (49 + Lunar Month - Lunar Age at the time of conception). If you get an odd number, it is a baby boy and if you get an even number, it is a baby girl.

Looking for an easy way to know the result? Just use our automated predictor below. We just need the birth date of the mother and the conception date. This tool works for year 2023, for year 2024 and for any year in the past !

Is the Chinese Gender Chart Predictor accurate ?

Short answer: not at all !

The accuracy of the Chinese Calendar predictor has been evaluated by scientific studies. For example, a study from 2003 analyzed 1,005 births in a private hospital in Dallas, Texas. An other study in 2009 even examined 38,394 births at Massachusetts General Hospital between 1995 and 2008.

In both cases, the conclusion is clear: there is no correlation between gender predicted using the Chinese lunar calendar and actual gender at birth. This just means that this method is not better than a coin toss ! So use it for fun if you like but don't rely on it !

We know how difficult it is to find reliable information on gender prediction on the internet. Many websites will tell you that some methods like Chinese Calendar or Ramzi theory are accurate even if there is no proof at all !

At Babygram, the only methods we trust to determine baby's sex with an utltrasound is the Nub Theory and our Image recognition algorithm. If you are looking for a reliable prediction based on scientific evidences, you can send your scan to our experts.
