What Is BaZi? The Four Pillars of Destiny Explained
What does “BaZi” mean?
Translated from Chinese, “BaZi” (八字) means “eight characters.” The method’s full name is BaZi Suanming (八字算命), or “fortune calculation by the eight characters.” Another name is Sizhu (四柱), meaning “four pillars.” This is where the English name “Four Pillars of Destiny” comes from.
The eight characters form four pairs. Each pair describes one part of a person’s birth time: year, month, day, and hour. The upper character is called a Heavenly Stem, and the lower one is called an Earthly Branch. A Stem and Branch together make one pillar.
Where did the system come from?
BaZi has its roots in the Chinese calendar tradition. As German sinologist Dr. Manfred Kubny, one of Europe’s leading BaZi experts, notes in his research, the first texts on calculating destiny from a birth date appeared as early as the third century. The method took its familiar form in the tenth century, when Master Xu Ziping made the day of birth the center of the analysis.
Over the past thousand years, BaZi has become one of the main systems used to describe personality in Chinese culture. It is practiced in Taiwan, Hong Kong, Singapore, Malaysia, and wherever Chinese communities live. People consult a BaZi practitioner when choosing a career, considering marriage, or making important family or business decisions.
What is a BaZi chart made of?
To create a chart, the date and time of birth are converted into the Chinese solar calendar. The year in this calendar begins not on January 1 or on Lunar New Year, but on Li Chun, around February 4. Months are also determined not by calendar dates but by solar seasons. For more about the seasons, see the 24 Solar Terms.
Here is the chart of a man born on October 3, 1943, at 10:20 p.m.:
The pillars are read from right to left: year, month, day, and hour. A chart has three important parts:
- Day Master. This is the Heavenly Stem of the day of birth. In this example, it is Yang Wood (甲). It represents the person—their “self”—and is the starting point for any analysis.
- The other seven characters. Each relates to the Day Master through one of the Five Element relationships: it supports the Day Master, is supported by it, controls it, is controlled by it, or is the same as it.
- Luck Pillars. These are successive ten-year periods that continue throughout a person’s life. In this example, the first begins at age eight. The birth chart does not change, while the Luck Pillars show the conditions life brings at different times.
The Five Relationships: how the elements correspond to areas of life
The Five Elements—Wood, Fire, Earth, Metal, and Water—generate and control one another. These relationships give each element in a chart its meaning for the person.
| Relationship to the Day Master | Name | What it represents |
|---|---|---|
| The same element | Friends | Siblings, colleagues, competitors |
| The Day Master generates it | Output | Talents, communication, creativity, active pursuits |
| The Day Master controls it | Wealth | Money, property, the results of one’s work |
| It controls the Day Master | Power | Authority, status, discipline, responsibilities |
| It generates the Day Master | Resources | Mother, knowledge, support, protection |
Let’s return to the example. The Day Master is Wood. Water (癸) generates Wood, so for this person it represents Resources. Metal (辛) cuts Wood, so it represents Power. Yin Wood (乙) in the hour pillar represents Friends. Earth (未) represents Wealth, because Wood controls it. Fire (午), which is nourished by Wood, represents Output.
This is only the first step. Next, a practitioner assesses how strong the Day Master is, which elements are beneficial and which may be challenging, and how all of this changes through the Luck Pillars.
How is BaZi different from a “zodiac sign by year”?
Many people know only their animal sign for the year: “I’m a Tiger” or “I’m a Rabbit.” In BaZi, this is just one of the eight characters, and far from the most important. Two people born in the same year can have very different charts because their month, day, and hour of birth differ.
BaZi also does not rely on the positions of the planets. Dr. Kubny describes it as an early Chinese system of chronopsychology: a person is born into a particular “climate” of time—the season, day, and hour—and carries its qualities throughout life.
What can—and can’t—you learn from a chart?
A BaZi chart can help you understand:
- which personality traits are strong and which may need support;
- the areas in which a person is more likely to thrive;
- which people and circumstances may be supportive;
- when more and less favorable periods may occur.
BaZi does not pass sentence on a person’s life. Chinese masters speak of luck in terms of opportunities. Knowing your chart can help you make the most of a favorable period and act more cautiously during a difficult one. The decisions are still yours to make.
How is BaZi connected to date selection?
BaZi is the basis for personal Day Stars. If a day clashes with the pillars in your chart—or, conversely, brings a beneficial element—it can affect the outcome of something you begin. That is why the same day considered “auspicious” on a general calendar may not suit everyone. Read more in the Personal Day Stars section.
How to get your chart
- Generate your chart using a BaZi calculator. You’ll need your date, time, and place of birth.
- Check your personal stars based on your date of birth.
- Choose a day for an important undertaking using the Auspicious Date Finder, or open the Personal Calendar, which already takes your chart into account.

Frequently asked questions
Do I need my exact birth time?
It is recommended. The birth time provides the fourth pillar, the Hour Pillar. Without it, the chart is incomplete, but you can still find your Day Master and Luck Pillars from your birth date.
Why doesn’t my BaZi year match my “horoscope”?
If you were born in January or early February, before Li Chun, BaZi places you in the previous year. Popular horoscopes often count the year from Lunar New Year or even from January 1.
Can I change my BaZi chart?
No. Your birth chart remains unchanged. But you can choose the timing of your actions, your surroundings, and activities that support beneficial elements. That is the purpose of auspicious date selection.
