A free web calculator for Four Pillars charts that computes birth year, month, day and hour stems and branches with solar-calibrated hour pillars, Day Master
The story so far
BaZi Calculator is a free tool for computing Four Pillars of Destiny charts accurately and learning to read them. The calculator takes your birth date, time and city and converts them into eight characters across four pillars—year, month, day and hour—each made of a heavenly stem and an earthly branch.
Every chart includes the Day Master, Ten Gods relationships, Five Elements distribution, and Luck Pillars showing ten-year periods. The calculator uses true solar time by default, accounting for longitude and the equation of time, and places the year boundary at the Start of Spring rather than the Chinese New Year. All rules are published and can be switched in Advanced settings.
Calculation requires no account or payment. Saving charts and accessing AI readings require a free Google sign-in. The site offers five additional tools: Zi Wei Dou Shu, Liu Yao, Mei Hua Yi Shu, Qi Men Dun Jia and the Chinese Almanac. The tool is available in English and Simplified Chinese.

Questions and answers
What if I don't know my exact birth time?
You can choose a time range or mark that you don't know. The calculator shows which pillars are fixed and which have candidate values instead of inventing an hour.
Why does the calculator use true solar time?
Traditional hour pillars follow the sun's position rather than clock time. You can switch to local clock time in Advanced settings if preferred.
Is this a scientific prediction tool?
No. Charts are reproducible under stated rules, but readings are cultural and reflective, not scientifically validated forecasts.
Can I export or share my chart?
Yes. You can print, save as PDF, or download as JSON.
