Hi, I’m Gabriel — a developer and an enthusiast of traditional Chinese culture.
I first came across the Chinese Gender Chart during my wife’s pregnancy. What started as simple curiosity quickly turned into a deeper interest. I found the idea fascinating — a traditional method that has been passed down and is still widely discussed today.
As I explored different websites and tools, I noticed that many of them didn’t fully reflect how the chart is traditionally used. Some tools relied directly on standard calendar dates without proper conversion, while others required users to know their exact conception date, which isn’t always practical. In some cases, the chart itself also varied across different sources.
That’s why I decided to build this tool.
The goal was simple: create a version that is easier to use while staying closer to the traditional method. This includes:
Automatically converting standard dates into lunar age and lunar conception month Supporting multiple ways to determine the conception date, including conception date, last menstrual period, and due date Using a version of the chart that is widely recognized in China — identified through research and discussions on platforms like Xiaohongshu (Rednote), where many users share their experiences and interpretations
This project is built with care and curiosity, and I hope it makes exploring the Chinese Gender Chart easier and more enjoyable for others.
