How to read a BaZi chart, pillar by pillar

A BaZi chart is eight characters in four columns. Reading one follows a fixed sequence: find the day master, judge whether it’s strong or weak, count the elements, then read the pillars for the areas of life they govern and the luck pillars for timing. Here’s that sequence, in the order a reader uses it.

1. Know what you are looking at

Four columns, right to left in the traditional layout: year, month, day, hour. Each column has a heavenly stem on top and an earthly branch below. Every stem and every branch carries an element. The branches also hide one to three further stems inside them, which is why an experienced reader counts more than eight elements. The zodiac animal is the branch of the year column.

2. Find the day master

It’s the stem of the day column, and it stands for you. Everything else is read relative to it: the stems that feed it, the ones it feeds, the ones that control it, the ones it controls. The ten day masters.

3. Judge strong or weak

Start with the month branch, the season. A wood day master born in spring, the wood season, starts strong; born in autumn, the metal season, it starts weak. Then count support elsewhere: the day master’s own element and the element that feeds it. As a rule of thumb, more than half the chart in support is strong; less is weak. This one judgement sets the direction of every piece of advice that follows.

4. Count the elements

Find which element dominates and which is missing. The dominant one is what you’re good at and overdo; the missing one is what you run short of and must supply. Then apply the cycles: the element that feeds your day master is the one to seek, and the one that controls it is the one to watch. The five elements.

5. Read the pillars by area

6. Read the ten gods

Each other stem in the chart is named by its relation to the day master: the ones that feed it are resources, the ones it produces are output, the ones it controls are wealth, the ones that control it are authority, the ones of its own element are peers. The family that dominates shows what the chart is organised around: being provided for, expressing, acquiring, being responsible, or standing alone.

7. Read the luck pillars for timing

Starting at an age set by your birth date, ten-year periods run in order, each with a stem and a branch. A luck pillar that supplies what your chart is short of is a decade that feeds you; one that adds to your excess is a decade to hold steady. The current year has its own pillar too, which is how a single year reads as a good one or a hard one. Timing with astrology and BaZi.

What Lumia does with this

Lumia casts the chart with the timezone your birth city had on your birth date, judges strong or weak, counts the elements, and writes the reading in plain language: what your dominant element makes you good at, what your weakest costs you, and how to supply it. The LifePrint draws your current decade as an arc. Back to BaZi.

Frequently asked questions

What are the eight characters?

Four heavenly stems and four earthly branches, one pair per pillar: year, month, day, hour. There are ten stems and twelve branches, each with an element; the sixty possible stem-branch pairs cycle through the calendar.

Which pillar is the most important?

The day pillar, because its stem is the day master: you. Next is the month pillar, because the season you were born in decides most of whether the day master is strong or weak.

What are the luck pillars?

Ten-year periods, each with its own stem and branch, that start at an age set by your birth date and run through your life. They're how BaZi reads timing: the same chart lives differently in a decade that feeds it and a decade that drains it.

Can I read my own BaZi chart?

The pillars and the element count, yes, with this page. The judgement — strong or weak, what to supply, how the luck pillars land — is where a reading earns its place. Lumia writes it from the chart it casts.
