Dao Almanac is built and maintained by the team behind Guan, a small practice of ordained Taoist consultants based in Sydney, Australia, working in the Zhengyi (正一) tradition. The calculators and articles here are written by practitioners who chart, select dates and read for real clients — not compiled from other websites.
Most English-language pages about BaZi, the Tong Shu and the Chinese zodiac get the boundaries wrong: they turn the year at the wrong date, read solar terms from day-level tables, and pad the rest with recycled filler. The boundaries are exactly where charts break. So we built the tools we wished existed: solar terms computed astronomically to the minute, the sexagenary day cycle anchored arithmetically, and honest warnings whenever a birth or a date falls close enough to a boundary that the answer genuinely depends on precision.
Everything here is free, runs in your browser, and stores nothing you type. We present a classical symbolic system as cultural heritage and a tool for reflection — never as a verdict on your life, and never as medical, legal or financial advice. We don't sell cures, we don't promise outcomes, and where the tradition itself is divided (as almanac houses often are), we say so on the page.
The site may display advertising through Google AdSense, and pages link to guan.life, where personal consultations are offered as a separate, paid service under its own terms. The free tools stay free either way.
Questions and corrections are welcome through guan.life. If you find a date where our calculation disagrees with a published almanac, we genuinely want to know — checking those edges is the whole point of this site.
