Free Calculators

Five tools, all running in your browser. Nothing you enter is uploaded or stored — the chart is calculated on your own device.

These tools compute the traditional systems as they are documented. They describe structure and terminology; they do not predict events.

BaZi Calculator

The four pillars from a date, time and timezone — with the ten gods, the day master and the ten-year luck cycles.

Chinese Zodiac Finder

Your animal from a full date. Uses the Lichun boundary, not the lunar new year — the difference that gets January births wrong.

Five Element Balance

How the four stems of your chart distribute across Wood, Fire, Earth, Metal and Water.

Compatibility Check

The classical branch relationship between two animals — six pairings, three-fold groups, oppositions and harms.

Dream Symbol Search

Search 216 indexed dream symbols across animals, objects, nature, actions and colors.

What the calculators do and do not do

They compute. The year pillar is fixed by Lichun (立春) rather than by the lunar new year, the hour pillar is fixed by the local clock time converted to the timezone you select, and the luck cycles follow the direction given by the year stem and the gender. Those are the three places where a calculator gets it wrong, and each one is handled explicitly.

For the vocabulary the calculators produce — day masters, ten gods, elements — see the BaZi database, the five elements and the zodiac database.
