Mayan Calendar Gender Calculator

To use the Mayan gender predictor: 1) Take the mother's age at conception, 2) Note the month of conception (1-12), 3) If both numbers are odd OR both are even, it predicts a girl. If one is odd and one is even, it predicts a boy. For example: Age 28 (even) + June/6 (even) = Girl. Age 27 (odd) + April/4 (even) = Boy.

The Mayan gender predictor has no scientific basis and is purely for entertainment. Like flipping a coin, it has roughly a 50% accuracy rate. Some claim 85% accuracy, but this is not supported by any scientific studies. The only reliable ways to determine baby gender are ultrasound (18-20 weeks), NIPT blood test (10+ weeks), or amniocentesis.

The Mayan method uses simple odd/even logic with the mother's age and conception month. The Chinese gender chart uses the mother's lunar age and lunar conception month in a more complex chart format. Both are ancient methods with no scientific validity, but they use different calculation approaches.

No gender prediction calculator is 100% accurate. The only medically accurate methods are: ultrasound (97-99% accurate after 18 weeks), NIPT blood test (99%+ accurate), CVS or amniocentesis (99%+ accurate). All calendar-based predictors like Mayan or Chinese are for entertainment only.

The ancient Maya had complex beliefs about gender and duality. They believed in balance between masculine and feminine energies. While the 'Mayan gender predictor' is popular today, there's limited historical evidence that the Maya actually used this specific method. It may be a modern interpretation inspired by Mayan numerology.

You can find out your baby's gender through: NIPT blood test (as early as 10 weeks, 99%+ accurate), Ultrasound (18-20 weeks for reliable results), CVS (10-13 weeks), or Amniocentesis (15-20 weeks). Gender prediction calendars like the Mayan method can be tried anytime for fun, but have no medical accuracy.
