Your birth year, month, day and hour, each written as two Chinese characters, a sky sign on top and an animal sign below, with their meaning in English underneath. Together they are your 8 characters.

Five elements shape your chart.

Wood, Fire, Earth, Metal and Water. Each one feeds another and tames (holds back) another, and everyone carries all five in a different mix. Chinese stargazers even named the five planets after them.

Fire

Fire feeds Earth, as it burns down to ash, and ash becomes soil.

Fire tames Metal, like a blacksmith's forge softening steel.

Around the circle, each element feeds the next: Wood feeds Fire, Fire feeds Earth, Earth feeds Metal, Metal feeds Water, and Water feeds Wood. Each one also tames another: Wood tames Earth, Earth tames Water, Water tames Fire, Fire tames Metal, and Metal tames Wood.

Eighty guardians, one sky.

Every chart leads to one of 80 guardian spirits. Your core element chooses the family (the columns). The strongest force in your chart chooses which one (the rows).

Ancient rules, worked out with care.

We follow the same rules Chinese astrologers have used for centuries. Treat what you find as a mirror to reflect on, not a prediction.

Rules that are 1,000 years old
We read your chart with the classical method written down in China about a thousand years ago, the one most BaZi readers still use today.
Your real birth time
Clocks round time off to the nearest time zone, but the sun doesn't. Tell us the city you were born in and we adjust the hour to where the sun really was.
Months that follow the sun
In BaZi a new month begins when the sun reaches a new season, not on the 1st, and the year begins in early February. That's why someone born on January 20 counts as the year before.
For the curious: the proper names
BaZi 八字
Literally “eight characters”: the year, month, day and hour of your birth, each written as two Chinese characters.
Four Pillars 四柱
Another name for the same chart: the four pairs of characters standing side by side.
Day Master 日主
What we call your core element: the top character of your day pair.
Heavenly stems 天干 and earthly branches 地支
The 10 “sky signs” and 12 “animal signs” (the Chinese zodiac animals) that make up the 8 characters.
Ten Gods 十神
The forces in your chart: how each other character relates to your core element.
Ziping method 子平法
The classical school of reading, named after Xu Ziping of the Song dynasty.
True solar time 真太陽時
Clock time corrected for your birthplace's longitude.
Solar terms 節氣
The sun's 24 seasons. Each month starts at one of them.
Stroke order 筆順
The book writes each character the way a calligrapher would, stroke by stroke, in the traditional order.
