Frequently Asked Questions
What is a Gender Prediction Calculator?
A Gender Prediction Calculator is a traditional tool that uses the Chinese lunar calendar method to predict a baby's gender based on the mother's lunar age and conception month. This ancient method has been used for over 700 years as entertainment during pregnancy, though it has no scientific basis.
How accurate is the Chinese Gender Prediction method?
Scientific studies show the Chinese gender prediction method has approximately 50% accuracy, which is no better than random chance. Medical research published in peer-reviewed journals confirms there is no scientific correlation between lunar age, conception month, and baby gender. It should be used purely for entertainment.
What is lunar age and how is it calculated?
Lunar age is your age according to the Chinese lunar calendar, typically 1-2 years older than your actual age. It's calculated by determining how many lunar years have passed since your birth, plus one additional year. Our calculator automatically converts your birth date to lunar age for accurate predictions.
Is the Gender Prediction Calculator free to use?
Yes, our Gender Prediction Calculator is completely free to use with no registration required. You can make unlimited predictions and calculations without any cost. All features including lunar age calculation, multiple prediction methods, and result sharing are available at no charge.
Can I use this calculator for family planning?
No, this calculator should not be used for family planning or medical decisions. It's designed purely for entertainment. For accurate gender determination, consult with medical professionals using ultrasound (95%+ accuracy after 15-20 weeks) or genetic testing like amniocentesis or chorionic villus sampling.
What information do I need to use the calculator?
You need your birth date and the conception date (or expected due date minus 280 days). If you're unsure of the exact conception date, you can use your last menstrual period date plus 14 days, or your due date minus 266 days. The calculator automatically handles lunar calendar conversions.
Are there other prediction methods available?
Yes, our calculator includes multiple traditional prediction methods including the Chinese lunar calendar, Ramzi theory (based on placenta position), and ring swing test. However, all traditional methods have similar accuracy rates around 50%. Only medical methods provide reliable gender determination.
Is my personal information secure?
Yes, all calculations are performed locally in your browser. No personal information is transmitted to our servers or stored anywhere. Your birth dates and results remain completely private and are only stored temporarily in your browser session.
