Bazi Chart: What It Is and How to Read One
A bazi (八字) chart is a small grid that turns your exact birth moment into eight Chinese characters, arranged in four columns. This page explains what a bazi chart looks like, how it is put together from your birth data, and how to start reading it, for first-time readers.
What Is a Bazi Chart?
A bazi chart, also called a Four Pillars chart, is the visual layout of your birth data in the traditional Chinese system. The name bazi means "eight characters," and those are what fill the chart: two for each of the four time units of your birth.
Think of the chart as a table with four columns and two rows. Each column stands for one part of your birth time, and each cell holds one Chinese character. Together, these characters describe patterns in your temperament, relationships, and timing. If you want the background on the system itself rather than the chart layout, see our guide on what is bazi.
A chart is a snapshot, not a scoreboard. It shows tendencies and natural leanings, not fixed outcomes, so it is best read as a description of how you are built, not a prediction of events.
How a Bazi Chart Is Built
Every chart starts from four pieces of information: your birth year, month, day, and hour. Each of these is converted into a pair of Chinese symbols using the traditional calendar. That conversion is the whole job of a bazi chart, and it is where accuracy matters most.
The conversion is not as simple as reading a Western calendar. The Chinese system counts months by solar terms, which are astronomical markers tied to the position of the sun, not by the numbered months on a wall calendar. This means the boundary between one month pillar and the next can fall on a different day each year, and it is calculated from the sun rather than looked up in a fixed list.
Because of this, building a chart by hand is slow and easy to get wrong. In practice, the calendar conversion, the solar term boundaries, and the pairing of characters are all handled by a calculator so the result is consistent. You enter your birth date, time, and place, and the tool assembles the eight characters for you.
The Structure of a Bazi Chart
Once built, the chart has a clear and repeating structure. There are four columns, one for each time unit, and they are usually read from left to right as Year, Month, Day, and Hour. Together these four columns are called the four pillars.
Each column has a top character and a bottom character. The top character comes from a cycle of ten signs called the Heavenly Stems (天干 Tian Gan). The bottom character comes from a cycle of twelve signs called the Earthly Branches (地支 Di Zhi). So the top row of your chart is four Heavenly Stems, and the bottom row is four Earthly Branches, giving you eight characters in total.
Top row: four Heavenly Stems. Bottom row: four Earthly Branches. The Day pillar stem is your Day Master. Generated by our free bazi calculator.
Each column also points to an area of life in a general way: the Year pillar leans toward roots and early environment, the Month pillar toward upbringing and work, the Day pillar toward the self and close partnership, and the Hour pillar toward later life and aspirations. These are broad associations, and a full reading weighs the whole chart rather than any single column on its own.
The Day Master and the Ten Gods
When you read a chart, you do not treat all eight characters as equal. One character is the anchor: the top character of the Day pillar, known as the Day Master (日干 Ri Gan). This single stem represents you, the person the chart belongs to.
Everything else is read in relation to the Day Master. The other characters are named by how they relate to it, using a set of labels called the Ten Gods (十神 Shi Shen). There are ten, in five pairs:
- Friend (比肩 Bi Jian) and Rob Wealth (劫财 Jie Cai): characters of your own element, standing for peers, siblings, and competition.
- Eating God (食神 Shi Shen) and Hurting Officer (伤官 Shang Guan): what you produce, such as skill, creativity, and self expression.
- Direct Wealth (正财 Zheng Cai) and Indirect Wealth (偏财 Pian Cai): what you act on, such as income, resources, and opportunity.
- Direct Officer (正官 Zheng Guan) and Seven Killings (七杀 Qi Sha): what acts on you, such as structure, duty, and pressure.
- Direct Resource (正印 Zheng Yin) and Indirect Resource (偏印 Pian Yin): what supports you, such as learning, mentors, and nourishment.
A label is a description, not a verdict. "Seven Killings" sounds alarming and often simply means you respond well to demanding environments. For these same ideas from a beginner angle, see our what is bazi guide.
Hidden Stems in the Branches
There is one more layer that makes the chart richer than it first appears. Each Earthly Branch quietly contains one to three extra Heavenly Stems inside it, called Hidden Stems (藏干 Cang Gan). These are not printed as separate columns, but they carry real weight in a reading, because they can add an element to your chart that does not show up in the visible eight characters.
The exact contents of each branch follow a traditional table, and a chart that looks light in one element on the surface may hold that element in its Hidden Stems. Working out which stems are hidden in each branch is fiddly by hand, so it is calculated automatically when your chart is generated.
- 戊本气 Main Qi正印 Direct Resource
- 乙中气 Middle Qi偏财 Indirect Wealth
- 癸余气 Residual Qi食神 Eating God
The Hour branch (辰) alone looks like one character, but it carries 3 Hidden Stems, each adding an element and a relationship to the reading. Generated by our free bazi calculator.
Five Elements in Your Chart
Every character in the chart belongs to one of the Five Elements (五行 Wu Xing): Wood, Fire, Earth, Metal, and Water. One of the first things a reader does is look at how these five are spread across the chart, including the Hidden Stems.
The goal is to see the shape of the chart: which elements are plentiful, which are scarce or missing, and how balanced the overall picture is. Season matters too, because an element can be naturally strong or weak depending on the time of year you were born. The way the elements produce and control each other is a topic of its own, which we cover on our Chinese elements page.
- Wood× 0
- Fire× 2
- Earth× 1
- × 2
- Water× 3
This example chart, for 15 June 1990 at 9:30 AM in New York, is heaviest in Water and has no Wood at all. Generated by our free bazi calculator.
Luck Pillars over Time
The four pillars describe the chart you are born with, but a full reading also lays out your Luck Pillars (大运 Da Yun): a sequence of ten year periods that begin a few years after birth. Each Luck Pillar is its own stem and branch pair, layered on top of the natal chart to show which elements come forward in a given decade of life. The starting age and direction come from your birth details, so they are worked out for you.
Each block is a ten-year Luck Pillar, layered on the natal chart from the starting age shown. Generated by our free bazi calculator.
True Solar Time and Your Chart
One detail can quietly change your chart: the exact clock time you use. The time on your birth certificate is standard zone time, a shared clock set for a whole region. It is not the real solar time over your specific birthplace. True Solar Time (真太阳时 Zhen Taiyang Shi) corrects for this by adjusting your recorded time for your location's longitude and for the natural variation in the length of a solar day.
This matters because the Hour pillar is defined by where the sun actually is. Since one Chinese hour spans two clock hours, a correction of even half an hour can move you into a different Hour pillar, which changes the branch, its Hidden Stems, and part of the reading. A chart built without this correction can quietly place you in the wrong hour, so our free bazi calculator applies True Solar Time automatically once you enter your birthplace.
Bazi Chart FAQ
What does a bazi chart show?
A bazi chart shows your birth moment written as eight Chinese characters across four pillars, along with their elements, the Hidden Stems inside each branch, and the relationships every character has to your Day Master. Read together, these point to tendencies in personality, relationships, and timing, not to fixed events.
How do I get my bazi chart?
You need your birth date, birth time, and birthplace. The birthplace matters because it sets your True Solar Time and therefore your Hour pillar. Enter those three details into a calculator and it will build the full chart for you in seconds, which is far more reliable than doing it by hand.
Is my bazi chart accurate?
The chart is only as accurate as the birth information behind it, especially the time. A wrong or rounded birth time can shift your Hour pillar, and skipping the True Solar Time correction can do the same. When your date, time, and place are correct, the calculated characters are consistent and repeatable.
What is my Day Master?
Your Day Master is the top character of your Day pillar, the Heavenly Stem tied to your day of birth. It is the symbol that represents you in the chart, and it is the reference point every other character is read against. A calculator identifies it for you as soon as your chart is generated.
Build Your Own Bazi Chart
