Who's behind this

Why I built this

I grew up reading the Four Pillars on my own family. My mother first showed me a chart when I was eight—not for the predictions, but as a way of understanding why people reach for what they reach for. The system stayed with me through engineering school, two careers, and a move to the United States.

For years I kept looking for an English-language calculator I could send to friends who got curious. Every option failed at least one of three tests: it gave the wrong day pillar (because it skipped the lichun boundary or true solar time), it refused to explain the math, or it tried to sell me a $500 "cure" for an element I was missing. The good Chinese-language tools never crossed the language line. The English ones felt like souvenir-shop renditions.

Eastern Pillars is the version I wished existed. The calculators run on open-source astronomical libraries I have reviewed and—where they fell short—wrapped with my own correction layers (true solar time, lichun edge cases, transparent zi-hour school selection). The interpretations are written in plain English without the dependence-creating "your chart is broken" theater common to fortune-telling marketing.

My background

I am not a professional astrologer and I do not claim lineage from a master. What I am is a careful reader who grew up in this tradition, in two languages, and who has spent enough time with the source texts (San Ming Tong Hui, Di Tian Sui, Yuan Hai Zi Ping) to know which English translations butcher the originals and which preserve them.

Every interpretation page on this site shows my review date and version number. When I update an interpretation because I have changed my mind or found a better source, I leave the version history visible. This is not a black box.

What this site will never do

• Predict your specific health outcomes or wedding date
• Tell you that your chart is "broken" or that you need a "cure"
• Sell 1-on-1 readings (this is a tool, not a consultation service)
• Charge a subscription (one-time PDF reports only)
• Hide the math behind a paywall

Get in touch

If you find an error in our calculation, a translation that loses the original meaning, or a place where we are being unclear, please write to hello@easternpillars.com. I read every email. Especially if you are a serious practitioner who finds us wrong about something—I would rather be corrected than be wrong.
