Four Pillars

BaZi calculator

Cast the year, month, day and hour pillars from your birth moment, with the day master, the ten-year luck pillars and the element balance, written in plain words rather than a table of characters. It runs in your browser and needs no account.

What you get

All four pillars with their Chinese characters and English names, computed for your exact birth time and longitude (the solar time correction most free calculators skip).
Your day master, the character that stands for you, with a reading in plain words.
The element balance: which of the five elements your chart leans on and which it lacks.
The ten-year luck pillars, laid on the same timeline as the Western forecast.
The year pillar for the year ahead and how it treats your day master.

Why it is read with Western astrology

The two systems were built on different sides of the world from the same sky. The Four Pillars read the day; Western astrology reads the hour and the planets. Side by side they correct each other, and the app writes each line with its source so you always know which one is talking.
