In your 7th week, you might encounter the “joys” of morning sickness, and by the 10th week, you might develop a specific food craving. Ancient Chinese and Mayan gender prediction calendars offer different insights. Can a calendar predict your baby’s gender?

What is the Chinese Gender Predictor Chart?

It is said that the Chinese gender calendar is more than 700 years old. The Chinese gender calendar was first discovered in a royal tomb near Beijing. For it to work, the mother’s age and date of conception must be converted to the Chinese lunar calendar. After that step is completed, then you must cross-check the data on a chart that predicts the baby’s sex.

Chinese astrologists suggest that even though there is no scientific evidence to support this method, the chinese gender predictor charts still do a relatively good job of revealing the sex of the baby. This old wives tales gender method is just for fun, so don’t rely on it for accuracy!

How To Use the Chinese Calendar Gender Prediction Method

This method of predicting a baby’s sex states that the lunar month of conception and the lunar age of the mother at the time of conception can tell you whether to expect a baby boy or a baby girl.

So to understand how to use this alternative method as a gender prediction test, you’ll need to look to the moon—that is, the lunar calendar.

The Chinese Lunar Calendar

The Chinese calendar consists of 12 or 13 months that alternate between 29 and 30 days, totaling about 354 or 384 days—depending on if it’s a 12-month year or a 13-month year.

  • Months – The months are based on the cycles of the moon. When the moon, sun, and earth are aligned—that is, during a new moon—the previous month ends and a new month begins. This is called “Chu Yi” or “Shuo Ri.” A full moon marks the middle of the month, waning every night until a new moon hangs in the sky to mark the next month.
  • Solar terms – The Chinese lunar year is divided into 24 solar terms, and each solar term is about 15 days. More specifically, one solar term is the time it takes the sun to move 15 degrees in the sky.
  • The new year – According to the Chinese lunar calendar, the new year is determined by the movement of the earth and the moon. The first day of the month that’s closest to the astronomical first day of the solar term—in mid-to-late January or February—becomes the first day of the new year.
  • Lunar age – According to the Chinese calendar, your lunar age is actually one more than your Gregorian age. A baby is considered one year old when they’re born, and on the first anniversary of their birth, the baby is two. Why the bonus year? According to tradition, a baby’s age begins in the mother’s womb.

Using the Chinese Lunar Calendar to Predict A Baby’s Gender

Now that we’ve covered the basics of the Chinese calendar, it’s time for some predictions! The Chinese gender prediction method actually starts with a Chinese birth chart. This one, in fact:

Chinese gender calendar chart

On the top of the gender prediction chart—or the X-axis—you’ll see months of conception in the Chinese lunar calendar. On the left side of the chart—also known as the Y-axis—you’ll see the mother’s lunar age at the time of conception.

Here’s how to put this ancient Chinese gender chart to use:

  • Add 1 to your age at conception. Remember, according to the Chinese lunar calendar, the day you were born counts as your first birthday.
  • Put your conception date (or as close as you can) into a Chinese-Gregorian calendar converter to determine the month number in which your baby was conceived.
  • Consult the chart.

For example: Let’s say you’re 31-years-old—according to a Gregorian calendar—and you conceived around March 18, 2020.

  • Your lunar age is 32 (adding 1 to age).
  • Your conception month is the 2nd month of the Chinese calendar year.
  • You’re going to have a girl!


While this is primarily a gender prediction method, many have used this chart to sway the odds for a baby boy or a baby girl. By consulting the Chinese birth chart, you can try to schedule the conception date to tip the scales in favor of your preferred gender, also known as gender swaying.

Chinese Calendar Method Accuracy

While it’s certainly a fun way to guess the gender of your little one, the Chinese calendar gender prediction technique hasn’t been backed by science. Researchers and scientists haven’t verified the accuracy of this gender prediction method. Which means it has a 50-50 chance of being accurate.

Where did the Chinese calendar gender prediction method come from?

The history of this particular gender prediction method is part mystery, part legend.

According to one account, the method was first revealed to the public in a Hong Kong newspaper in the 1970s. The article states that this Chinese gender predictor tool was used in the imperial court of the Qing Dynasty.

The Qing Dynasty lasted from 1644–1911, so the writers weren’t able to pinpoint exactly when the method began. They did claim that the method was written on a specific document and kept hidden by trusted eunuchs. The method was kept a closely guarded secret, used only by elite families. When the Qing Dynasty ended, the document disappeared—some say to Great Britain—but one scholar was able to copy the chart and the method.

Another account says that this method of gender prediction was discovered 700 years ago—during either the Ming or Yuan Dynasty—in an ancient Chinese imperial tomb. How ancient? It’s hard to say. The earliest Chinese dynasty dates back to 2070 BCE, so this method might have been used for thousands of years.

Other Chinese Methods of Gender Prediction

There are a wide variety of gender prediction methods that do not involve charts, age, or which lunar month a baby is born in. In 2009, researchers published a sociological study of pregnant women in China. The study asked whether the women hoped for a boy or a girl, what gender they thought their babies would be, and various methods and explanations for why they believed they were having a boy or a girl.

Here are a few other ways Chinese women predict the gender of their baby:

  • Dreams – In their interviews, researchers discovered that dreams were a popular way to predict a baby’s gender. Dreaming of a snake is a sign you’re having a boy, dreaming of flowers indicates a girl.
  • Mom’s appearance – We believe that all pregnant women—and all women!—are beautiful. But according to some interviewees, how you feel about your appearance indicates whether you’re having a boy or a girl. If you’re enjoying a pregnancy glow, you’re going to have a girl. If not, you may be having a boy. According to one study participant, “Because I turned ugly after I became pregnant, it is going to be a boy.” If you relate to this mom-to-be’s statement and do wind up having a boy, maybe leave that part out of your birth story when he gets older.

Additional Chinese Gender Prediction FAQs

What Is The Difference Between Gender and Sex?

Gender and sex are terms often used interchangeably, but they hold different meanings. Sex refers to the biological attributes such as male or female based on physical characteristics. Gender, on the other hand, is a social and cultural construct encompassing roles, behaviors, and identities that society associates with being masculine or feminine. The Chinese gender prediction method is more focused on predicting the biological sex of the baby rather than their gender identity.

When Can You Use The Chinese Gender Predictor?

The Chinese Gender Predictor method can be used once you have the mother’s age at conception and the lunar month of conception. This typically becomes possible after the first trimester when the mother’s age and the conception date are known.

Does The Chinese Gender Predictor Change Each Year?

No, the Chinese Gender Predictor chart remains consistent and doesn’t undergo changes on an annual basis. The only variables that influence the Chinese Gender Predictor are the mother’s lunar age and the baby’s due date.

Are There Multiple Gender Predictor Charts?

There is only one official Chinese Gender Prediction Chart. While there may be variations floating around the internet, the original has never changed and may always stay the same. If you find another Chinese Gender Chart different from the one above, then most likely it is unauthentic.

Should I Use a Chinese Gender Predictor?

No harm, no foul for using a Chinese gender predictor! This method is one of the fun and entertaining test methods for determining if you’re having a boy or girl baby. So why not give it a try? Just keep in mind this is purely for fun. Don’t take the results too seriously or start picking out colors for the nursery.
