Frequently Asked Questions

What is the Chinese Gender Predictor?

The Chinese Gender Predictor is a traditional method used to guess a baby's gender based on the mother's lunar age at the time of conception and the lunar month of conception. It dates back over 700 years and is rooted in ancient Chinese family planning traditions. It's also known as the Chinese Lunar Calendar (CLC) method.

How accurate is the Chinese Gender Predictor?

The Chinese Gender Predictor is considered a fun, cultural tradition rather than a scientifically validated method. Studies show its accuracy is roughly 50-50, similar to a random guess. It should be used for entertainment purposes only and is not a substitute for medical gender determination methods like ultrasound.

How does the Chinese Gender Predictor tool work?

The tool converts your Gregorian birth date and conception date into the Chinese lunar calendar. It then calculates your lunar age at the time of conception and cross-references that with the lunar conception month on the traditional Chinese gender chart to predict Boy or Girl.

How is the Chinese lunar age measured?

Chinese lunar age is calculated differently from Western age. In the Chinese system, a baby is considered 1 year old at birth, and a year is added at each Chinese New Year rather than on the birthday. This calculator automatically converts your Gregorian date of birth into the correct lunar age.

When can I use the Chinese Gender Predictor?

You can use the Chinese Gender Predictor at any point during pregnancy, as long as you know your date of birth and approximate conception date. Many people use it as soon as they find out they are pregnant, well before an ultrasound can confirm the gender.

Is the Chinese Gender Predictor applicable for twins or multiple pregnancies?

The traditional Chinese gender chart was not designed for twin or multiple pregnancies. Since it predicts a single outcome based on one conception month and the mother's lunar age, it cannot reliably account for multiple babies. It is best suited for single-baby pregnancies.

Does the Chinese Gender Predictor change every year?

The underlying Chinese gender chart itself remains constant, but your lunar age and the lunar month of conception will naturally differ with each pregnancy. So while the chart doesn't change, the inputs — and therefore the prediction — will vary depending on when you conceive.

What is the Chinese Zodiac and how is it determined?

The Chinese Zodiac is a 12-year cycle where each year is represented by an animal sign (Rat, Ox, Tiger, Rabbit, Dragon, Snake, Horse, Goat, Monkey, Rooster, Dog, Pig). Your zodiac sign is determined by your lunar birth year. This calculator identifies your zodiac sign based on your date of birth.
