In a time before ultrasounds, gender determination was grounded on speculation rather than scientific truth.
Case in point: people can apparently “tell” whether a woman is having a boy or a girl by the way they are carrying; low for a boy and high for a girl.
Given there were only two gender choices, it wasn’t surprising that many of the guesses proved to be right.
Today, modern technology is a more accurate determiner of a baby’s sex. Although that is the case, many antiquated beliefs in determining the gender of an unborn child still exist – and will likely never disappear.
While delivering a healthy baby is a priority, some mothers-to-be have a secret desire to birth a child of a particular sex.
After all, pregnancy is both a mystery and miracle despite the multitude of science published about it. Plus, some find it a bit entertaining to try and guess the sex of a baby.
One of the gender prediction methods that can be tried was apparently used by one of the most ancient civilizations: the Mayans.
The Mayan Gender Predictor Chart
The Mayan civilization was noted for many things: art, architecture, an astronomical system, a calendar, and mathematics.
Apparently, they also have a chart for predicting the gender of an unborn child. The method is quite simple: take the mother’s age at the time of conception as well as the number of the month of conception.
If both numbers are odd or even, then the child would be a girl. On the other hand, if either number is odd or even, then the expected child is a boy.
| Mayan Gender Predictor Chart | ||
|---|---|---|
| Age at Conception | Month of Conception | Gender |
| Even | Even | GIRL |
| Odd | Odd | GIRL |
| Even | Odd | BOY |
| Odd | Even | BOY |
Here are examples to illustrate the method better:
- If a mother was 23 years old at the time of conception and she conceived on the month of May, she will have a baby girl. Twenty-three is an odd number, and May is the fifth month, so the combination of two odd numbers results in a female child.
- If a mother was 26 at the time of conception with June being the conception month, she would have a baby girl. Twenty-six is an even number while June is the sixth month and according to the Mayan gender predictor chart, the combination of two even numbers results in a female child.
- If a mother was 25 years old when she conceived with conception in the month of October, her child would be a boy. Twenty-five is an odd number while October is the tenth month and an odd-even combination results in a male child.
- If a mother conceived when she was 28 years old on the month of March, she would have a male child. Twenty-eight is an even number while March is the third month and an even-odd combination, according to the chart, results in a baby boy.
Although there is no scientific evidence for this method, or any other ancient gender prediction method (like Chinese Gender Predictor), some find that there’s no harm in using the method to venture a guess on a baby’s gender.
Gender Determination with Modern Technology
Although science is far more reliable in determining the gender of an unborn child, imaging technology doesn’t produce a 100% result.
However, being able to determine a child’s sex 98% of the time is pretty accurate. It’s important to note that accuracy relies on a number of factors, including:
- The position of the fetus. A fetus needs to be in an ideal position to get an accurate result. For instance, gender determination is difficult when a child keeps their legs together.
- The time when the ultrasound was performed. An early ultrasound is not an accurate way to determine a baby’s sex. Ultrasounds carried out at 12 weeks aren’t entirely accurate as external genitalia aren’t fully external yet. A more definitive answer can be had during the 20-week anatomy scan.
- The presence of multiple babies. When a woman carries twins, triplets, or even more makes gender determination a bit harder as other babies can be hiding their siblings.
Although ultrasounds are still the best way to determine a child’s gender despite not being 100% accurate, there’s nothing stopping mothers from having a bit of fun and trying out some ancient methods like the Mayan gender predictor chart.
Hello, I am 20, conceived in October. what would be the prediction? I really really really want a little daughter 🥺
according to the mayan gender predictor it would be a girl. do note that this is just a myth 🙂
I am 30 years and would like to conceive in jan 2020.. according to Mayan the gender is boy right
correct
hi, my last menstrual was in October 17 and I am 23 years old. would this say i’m having a boy? if i am, it is mistaken
Jessie, the mayan gender predictor is very unreliable, should only be used for entertainment purposes 🙂
I have 5 children and expecting my 6th. According to the MAYAN chart I have given birth to 4 Girls and 1 boy. 1) 19 y/o-7/2003. 2) 21 y/o-7/2005. 3) 23 y/o- 5/2006. 4) 24 y/o-10/2007. 5) 26 y/o-12/2009.
According to my results thus far, It is very accurate. According to the chart my 6th child is a baby girl . I will post as soon as I know the gender.. (btw, no sex preference, just for fun). Best of luck to all!!
Hello there ,
I am 29 years old now and conceived in august 08th month , so am i expecting a boy ? How effective is this prediction ? I am too curious to know abot it ❤❤
Hi Simran, based on the calendar yes you would be expecting a boy. A lot of people swear by the Mayans predictor. Good luck finding out what you are having!
I’m 36 and conceived in June, what would be my baby’s gender plz
Hi Jessy, According to the Mayan predictor, you would be having a girl. However, this is not a guaranteed test as you already know.
I was of 29 when I had conceived and my last menstrual date was 21 August 2018…according to mayans I will get a boy. Am I right?
Hi Meerab, well it depends. While it’s always 50/50 based on the conception calculator you would have conceived between August 31st and September 8th. So while you LMP was in an even month which according to the chart stated boy, you could have conceived in September, which is an even month which they state would be a girl. So again, it’s 50/50. You seem to fall on the cusp of an odd and even month. Good luck!
I completed 33 years in March 2018 and conceived in October (most probably before 10th Oct)….How do I know the gender of baby ????
Hi Manreet, according to the Mayan gender predictor with an ODD/EVEN match, a boy. However, the best way to know what you are having is to get an ultrasound and see your doctor which you should have done already. By 18 weeks they can generally do an anatomy scan to determine the gender. Congratulations and good luck!

Hello Anand, the below link will help you:

Difference in mayan gender chart and mayan gender predictor.
I am 22 and trying to conceive this month that is September 2017.
so, 22 is even and 9 is odd. Thus, it must be a boy.
According to the gender chart, 22 years and September month intersects to conclude a girl in the chart. Please clarify.
Hello Sandhya, please see links below on how to conceive a boy and a girl:
https://womanjunction.com/tips-conceive-boy/
https://womanjunction.com/tips-conceive-girl/
September is month 9 an off number. The age 22 is even… This predicts a boy. If the month is even and age is even it’s a girl if month is odd and age is odd it’s a girl. Is either number is odd it’s a boy (22 and 9… Or 23 and 10)
I have completed my 28 year on last 5th of September 2017 according to Mayan gender prediction what age should I count to get accurate answer for conceiving baby boy. Should I count running 29 year or completed age.
Hello Kuldeep, use the below link with tips on how to conceive a baby boy:

The one is Mayan and the other is Chinese. Either way, you have a 50/50 chance of the gender.
Anand, according to this article, you are having a boy – your age is an even number and your month of conception is an odd number. Your doctor will be able to provide a more accurate answer with modern technology though, as this method is not always correct.
