The Chinese birth gender chart, an ancient gender prediction method, is a fun way to guess the gender of an unborn child. To use the chart, you need only two pieces of information — the lunar month and the lunar age of the mother when the baby is conceived. There is no proof that the Chinese birth gender chart is accurate, but some people swear by it, and most people use it just for fun.

Figuring Out Gender

  1. 1
    Find out the mother's lunar age at the time of conception. The Chinese use a lunar calendar, which is different from the Western Gregorian calendar. For this reason, you're going to have to calculate the mother's age according to the lunar calendar, not the Gregorian calendar.[1]
    • First of all, add one year to however old you are right now. You're 32 years old right now? According to the Chinese calendar, you're at least 33 (possibly 34). This is because the Chinese count the first nine months spent in the womb towards the baby's age, unlike in the West. So when a baby is born, it's already 1 year old according to the lunar calendar.
    • If you were born after February 22, take your Gregorian age, add 1 (from the roughly year you spent in your mother's womb), and you're done. If you're 17 and you were born on July 11, you're 18 according to the lunar calendar.
    • If you were born before February 22, find out if your birthday comes before or after the Chinese New Year during the year you were born. If you were born before the Chinese New Year, add an additional year to your Gregorian age.
      • For example, you were born on January 7, 1990; the Chinese New Year during 1990 happened on January 27, meaning you were born before the New Year, according to the lunar calendar. This makes you two years older, in lunar years, than you are according to the Gregorian calendar.

  2. 2
    Determine the lunar month during which the baby was conceived. If the baby has not yet been conceived, determine the month that you would like the baby to be conceived, or just work backward: use the calendar and desired gender to determine when you should conceive.[2]
    • The easiest way to convert the actual month or the desired month of conception to the lunar calendar is to use an online converter. Type in "Gregorian to lunar calendar conversion," or use the one supplied here

    Using the graph below, find the place where your lunar age and the child's conception month intersect. Start from your lunar age at the time of conception and move right until you find the lunar month when the child conceived. This will give you either a G (girl) or B (Boy).[3]

Additional Information

  1. 1
    Use the birth chart to try to select which gender you ideally want. While many families use the Chinese birth chart after a child has been conceived, some couples look to the birth calendar before conception to select a boy or girl specifically. Whatever gender your child is, you're sure to love them; but what if you could figure it all out beforehand?
  2. 2
    Remember that accurate readings always involve the Chinese lunar calendar and dates based on the time of conception.
    • Birth charts that don't use the lunar calendar as a guide aren't accurate. Beware of readings that use the Gregorian Calendar.
    • Be sure to select dates based on the date of conception, especially when considering age. Select how old you were at the time of conception, not how old you currently are.
  3. 3
    Know that there is no scientific basis to the Chinese birth chart. Science has been unable to verify the accuracy of the Chinese birth chart, so be careful using the chart solely to determine or predict the gender of your child. There are several ways to scientifically predict the gender of your unborn baby — ultrasound, amniocentesis — but the Chinese birth chart is not one of them.

    Once you are around five months pregnant, you can have an ultrasound done by your doctor to see the sex of your child. By that time, genitals (penis, testicles/ vagina) will be clearer to identify.

Warnings

  • Consult other scientific methods of predicting gender in a baby. Never rely solely on the Chinese birth chart to accurately predict the gender of your unborn child.[4]

Article SummaryX

To use the Chinese birth gender chart to determine your baby’s gender, start by calculating your lunar age by adding 1 year to your age. If you were born before February 22nd, find out if you were born before or after the Chinese new year on your birth year. If you were born before the Chinese new year, add a second year to your age. For example, if you were born on January 7th, 1990, you’d add 2 years to your age, since Chinese New Year was on January 27th that year. Once you’ve calculated your own lunar age, work out the lunar month your baby was conceived in by using an online Gregorian to Lunar calendar converter. Then, use the Chinese birth gender chart to find where your lunar age and your child’s conception month intersect, which will tell you their gender. Keep in mind that this method is not scientifically proven and should not be used in place of an ultrasound. For more tips, including how to predict the gender of a child before you conceive, read on!
