BaZi Calculator

BaZi Calculator (bazicalculator.pro) is a free, transparent tool for Chinese Four Pillars (BaZi) charts. Enter a birth date, time and place and it computes the year, month, day and hour pillars using true solar time by default (longitude plus equation of time), years from the exact Start of Spring instant, months from the twelve jie solar terms and a 23:00 day change. The chart shows the Day Master, Ten Gods for every stem and hidden stem, a transparent Five Elements count, and ten-year Luck Pillars with exact starting age. Every chart carries a rule-set ID so results are reproducible. Beyond
