Use it as a free reference if you want the background; if you want a personal chart or reading, a chart-casting site fits better.
What it does
Stem-Branch is a free web page that digs into the origins and calendrical calculations of the Seven Governors and Four Remnants (Qi Zheng Si Yu), a branch of Chinese astrology. It is written for people who want to understand the historical and technical background rather than get a personal reading.
There is no chart casting or interactive tool here; it is a text-based examination. You read it in your browser at no cost, and it suits hobbyists and students of astrology's history who are comfortable with some technical detail.
Because it is a static GitHub Pages site, expect a plain, document-like layout. Treat the material as educational context for entertainment and self-reflection, not as a predictive system.
