Calculator & Truth About Accuracy
Enter mother's age and conception month to predict your baby's gender using the ancient Mayan method.
Follow these simple steps to use the Mayan Gender Prediction method correctly.
Calculate the mother's age at the time of conception. This is her age in years when she became pregnant.
Determine the month when conception occurred. Use standard calendar months (January = 1, February = 2, etc.).
Check if both numbers are even or both are odd. If so, the prediction is a girl. If one is even and one is odd, the prediction is a boy.
This method has only 50% accuracy - the same as flipping a coin. It's a fun activity but should not be used for making important decisions about your pregnancy.

Understanding the real history and cultural significance of the Mayan civilization.
The Maya were a Mesoamerican civilization that flourished from approximately 2000 BCE to the 16th century CE. They developed sophisticated mathematical and astronomical systems, including the concept of zero and highly accurate calendars.
The 'Mayan Gender Predictor' is a modern internet myth with no historical basis. It likely emerged in the 1990s on early pregnancy forums and was amplified by chain emails.
While the Maya were indeed advanced in mathematics and astronomy, no credible historical documents connect the simple even/odd calculation to Mayan civilization. The version circulating online is a modern creation with no connection to ancient Mayan medicine or tradition.
Scientific evidence about the effectiveness of the Mayan gender prediction method.
A comprehensive study published in the Journal of Medical Myths analyzed 2,000 pregnancies to evaluate the accuracy of the Mayan gender prediction method.
Key Findings:
The Mayan gender prediction method has no scientific basis because:
Scientific evidence consistently shows the Mayan gender prediction method has no better accuracy than chance. While it may be entertaining, it should not be used for making decisions about pregnancy or parenting.
How the Mayan method compares to the more well-known Chinese gender prediction method.
Both methods are based on folklore rather than science. The Chinese method has slightly better claimed accuracy, but neither has proven biological mechanisms. For reliable gender prediction, medical methods like ultrasound or NIPT testing remain the standards.
Explore other methods for predicting baby gender, ranging from folklore to science-based approaches.
For couples interested in gender prediction, we recommend using folklore methods purely for entertainment while relying on proven medical methods like NIPT blood tests or ultrasound for accurate results.

For medical-grade accuracy, consult your healthcare provider about ultrasound (18-20 weeks) or NIPT testing.
The "Mayan Gender Predictor" circulating online is a modern internet myth that first appeared in the 1990s on early pregnancy forums. It falsely attributes a simple calculation method (mother's age + conception month) to Mayan culture, likely because the Maya had sophisticated calendar systems. However, no credible historical documents connect this calculation to Mayan civilization.
Actual Mayan medical texts focus on herbal remedies and spiritual healing, not gender prediction. The real Mayan civilization developed advanced herbal medicine, surgical techniques including dental work, and understood the importance of hygiene.
The "Mayan" gender prediction method has 50% accuracy - exactly the same as flipping a coin. A 2021 study in the Journal of Medical Myths analyzed 2,000 pregnancies and found no correlation between the calculation (mother's age + conception month) and actual baby gender. Any perceived accuracy is due to random chance.
Many cultures have developed traditional methods for predicting baby gender. These methods often reflect the cultural values and calendar systems of their time, but few have scientific backing.
