About Me

Hi, I'm Sukie Gao — you may know me online as Sukie Chinese on Instagram and YouTube. I grew up in Beijing and currently split my time between Beijing and Shanghai. I used to work as a Chinese-language teacher with international students, which is where most of my interest in folk customs, the lunar calendar, and naming traditions comes from. Teaching pushed me to know the “why” behind the language, not just the grammar. I also have a daughter, born in 2024.

The Chinese Gender Calendar is one of those traditions that comes up around Chinese family dinners and baby announcements, yet the English-language information about it online is messy. Lunar age was rarely explained correctly. Charts were presented as scientific tools when they're really cultural folklore. The history was often invented.

That's why I started ChineseGenderCalendar.org. I wanted a place where the tradition is shared with respect, the math is right, the cultural context is real, and the “this is for fun, not science” line is never blurred. I prefer to keep my personal life private, so the site describes Chinese customs in general rather than telling stories about real people. Where a page needs an example, it uses a clearly labelled illustrative one, with every lunar age and month computed by the same code as the calculator.

What I Write About

  • The Chinese lunar calendar and how it differs from the Western calendar
  • The history and folklore of the Chinese Gender Calendar
  • How to use the calendar correctly (lunar age, conception month conversion)
  • What the science actually says about prediction accuracy
  • Cultural traditions around pregnancy in Chinese families

My Approach

I research with AI assistance (it's a great drafting tool) but I edit everything myself before publishing. Anything cultural is checked against multiple Chinese-language sources. Anything about accuracy or biology is checked against peer-reviewed studies and authoritative medical sources like the American College of Obstetricians and Gynecologists (ACOG) and the National Institutes of Health.

I do not give medical advice. The Chinese Gender Calendar is folklore. For real gender determination, please talk to your doctor.
