About ChineseGenderCalendar.org
ChineseGenderCalendar.org is a free, ad-supported resource dedicated to the traditional Chinese Gender Calendar. We built this site to help expecting parents explore one of the oldest folklore traditions surrounding pregnancy, presented in a clear, accurate, and culturally respectful way.
Our Mission
Our goal is simple: make the Chinese Gender Calendar easy to use, accurate in its historical form, and honest about what it can and cannot do. Many online calculators cut corners on lunar age conversion or present the chart as if it had medical value. We believe expecting parents deserve better.
Every page on this site is designed to balance two ideas: respect for the tradition, and clarity about the science. The Chinese Gender Calendar is a centuries-old cultural artifact worth preserving, but it is not a substitute for modern medical gender determination. We say both things clearly, every time.
What We Offer
- A free Chinese Gender Calendar calculator that handles all lunar conversions automatically
- A dedicated lunar age calculator for standalone age conversion
- Year-specific charts for 2026, 2027, 2028, and 2029
- In-depth educational guides about the chart, its history, and the lunar calendar system
- Honest analysis of the chart's accuracy based on published research
- Practical context on medical gender prediction methods used in the United States
Our Editorial Standards
Every article on this site is researched against multiple historical sources for folklore content, and against peer-reviewed studies for any claims about accuracy or biology. When we reference a study, we cite the publication. When a claim is traditional rather than scientific, we say so clearly.
We never present the Chinese Gender Calendar as a medical tool. Where a topic touches on medical decisions, we direct readers to consult licensed healthcare professionals. Our content is written for cultural interest, entertainment, and education — not as a substitute for a doctor's guidance.
Pages are reviewed periodically and updated when we find better sources, correct errors, or expand coverage of topics that readers ask about.
How the Site Is Funded
ChineseGenderCalendar.org is free to use and always will be. The site is supported by display advertising and affiliate links to pregnancy-related products. When you click on an affiliate link and make a purchase, we may receive a small commission at no additional cost to you. This helps cover hosting, development, and ongoing research for the site.
Advertising and affiliate relationships never influence the editorial content on this site. We recommend products that we believe expecting parents may find useful, and we clearly label promotional sections so they cannot be confused with editorial content.
A Note on Accuracy
The Chinese Gender Calendar has been studied multiple times in peer-reviewed research, and the consistent finding is that its predictive accuracy sits around 50% — the same as a coin flip. We present the chart as a cultural tradition and a fun activity, never as a reliable predictor. For confirmed gender information during pregnancy, please speak with your healthcare provider about NIPT, ultrasound, amniocentesis, or other medical options. You can read our full analysis on the accuracy page.
Privacy and Data
We take reader privacy seriously. The calculator on our site runs entirely in your browser, and we do not store the birth dates, conception dates, or predictions you enter. For details on the analytics and advertising data we do collect, please see our Privacy Policy.
