Free BaZi Calculator is a web-based Chinese astrology tool that generates a Four Pillars (BaZi) chart from birth date, time, place, and gender. It produces a structured reading covering Day Master, Five Elements balance, Ten Gods, shensha, and five-layer luck timing (decade to hourly) without requiring sign-in for the core chart. The tool corrects for true solar time using geographic longitude and follows published Ziping-pai tables for hidden stems and 30+ shensha annotations.
What is Free BaZi Calculator?
It is a free online BaZi chart generator that takes birth date (year, month, day), hour, minute, birth place (city or district), and gender as input. Output includes the four pillars (year, month, day, hour) with heavenly stems and earthly branches, Day Master identification, Five Elements distribution with weighted scoring (stems 2, branches 1, hidden stems 1.5, residuals 0.75), and a nine-module reading (overview, personality, career & wealth, relationships, learning, rhythm & health, timing, action). The platform runs as a web app accessible on any modern browser.
