What is BaZi (Four Pillars of Destiny), and what does a chart actually show?

BaZi, the Four Pillars of Destiny, is a chart of eight characters in four pillars: year, month, day, and hour. Each pillar is one Heavenly Stem and one Earthly Branch. The chart shows temperament tendencies and the rhythm of time. The month pillar's Earthly Branch, the Month Command, names the season those characters sit in. A wedding date, a diagnosis, a verdict, or a price stays on the record that already holds it, with the qualified person who keeps that record.

Health, legal, financial, and mental-health decisions belong with a clinician, a lawyer, an adviser, or a therapist. See a professional for those questions. A BaZi chart can organize tendencies and a time window around a decision you can already describe.

What are the four pillars in a BaZi chart?

A BaZi chart holds a year pillar, a month pillar, a day pillar, and an hour pillar. Each pillar is one Heavenly Stem and one Earthly Branch, so the four pillars are eight characters. The same birth time keeps those eight characters.

The year pillar and the month pillar follow a solar-term table. Start of Spring opens the year. In this site's table, Start of Spring in 1984 falls on February 4. At noon on February 2, 1984, the year pillar is Gui Hai and the month pillar is Yi Chou, a winter month. At noon on February 6, 1984, the year pillar is Jia Zi and the month pillar is Bing Yin, a spring month. If you were born within a day of a solar term, check the exact time of that term in an almanac before relying on the year or month pillar.

The 12 month branches open on 12 sectional solar terms: Minor Cold for Chou, Start of Spring for Yin, Awakening of Insects for Mao, Pure Brightness for Chen, Start of Summer for Si, Grain in Ear for Wu, Minor Heat for Wei, Start of Autumn for Shen, White Dew for You, Cold Dew for Xu, Start of Winter for Hai, and Great Snow for Zi.

The hour pillar uses 12 branches of two clock hours: Zi 23:00–00:59, Chou 01:00–02:59, Yin 03:00–04:59, Mao 05:00–06:59, Chen 07:00–08:59, Si 09:00–10:59, Wu 11:00–12:59, Wei 13:00–14:59, Shen 15:00–16:59, You 17:00–18:59, Xu 19:00–20:59, and Hai 21:00–22:59. This site moves the day pillar to the next date at 23:00. At 23:15 on August 21, 1995, the day pillar is Yi You, the day pillar of August 22, and the hour pillar is Bing Zi. Recording an uncertain hour, and labeling a birthday near a solar term, is covered in what birth information a reading needs.

What are the Heavenly Stems and Earthly Branches?

The 10 Heavenly Stems, in order, are Jia, Yi, Bing, Ding, Wu, Ji, Geng, Xin, Ren, and Gui. They pair into the Five Elements. Jia and Yi are Wood. Bing and Ding are Fire. Wu and Ji are Earth. Geng and Xin are Metal. Ren and Gui are Water. Jia, Bing, Wu, Geng, and Ren are yang. Yi, Ding, Ji, Xin, and Gui are yin.

The 12 Earthly Branches, in order, are Zi, Chou, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu, and Hai. Yin, Mao, and Chen are spring. Si, Wu, and Wei are summer. Shen, You, and Xu are autumn. Hai, Zi, and Chou are winter.

This site spells two different characters as Wu. The fifth Heavenly Stem is Wu, and the seventh Earthly Branch is Wu. In a pillar that uses both, the first Wu is the stem and the second Wu is the branch. Stems and branches step forward together and repeat after 60 pairs. Jia Zi is one of those 60.

What does the day pillar mark in a BaZi chart?

The day pillar in a BaZi chart is the Heavenly Stem and Earthly Branch of the birth day. This site changes that day at 23:00, so a clock time before 23:00 keeps the pillar on the calendar date. At noon on October 1, 1949, the day pillar is Jia Zi. At noon on January 1, 2000, the day pillar is Wu Wu, stem Wu beside branch Wu.

The Heavenly Stem of the day pillar is the Day Master, the reference character the other stems are read against. Finding that stem on your own chart, and why its strength is read from the whole chart, is a separate question.

Noon on January 1, 2000, fills every pillar: year Ji Mao, month Bing Zi, day Wu Wu, hour Wu Wu. A personal reading runs this calculation on the birth date and time you provide and leaves the four pillars visible for checking.

What is the Month Command in a BaZi chart?

The Month Command in a BaZi chart is the Earthly Branch of the month pillar. At noon on January 1, 2000, the month pillar is Bing Zi. Zi belongs to winter, so the Month Command is winter. That noon also falls before Start of Spring, which is why the year pillar is still Ji Mao.

This site follows the Ziping frame: the Month Command is the seasonal outline, and the Heavenly Stem of the day pillar is the reference character inside that season. A Bing day stem in a Zi month and a Bing day stem in a Wu month share a stem and sit in winter and in summer. Another common approach leads with a Day Master personality type and treats the month branch as background. That order makes the conclusion a single character label.

Ziping luck pillars start from this same month pillar. Each one runs 10 years. How to use a luck pillar is a separate question. How to turn a vague worry into a question a reading can answer names the 10-year count only as part of fixing the chart.

What does a BaZi chart show about temperament and time?

A BaZi chart shows temperament as a tendency inside the Month Command's season. In the noon chart of January 1, 2000, that season is winter, from the branch Zi, and the day stem is Wu, yang Earth. Set the pairing beside a role, a household duty, or a deadline already on your calendar.

A BaZi chart shows time as rhythm: four pillars fixed for one birth time, one season from the Month Command, and Ziping luck pillars of 10 years counted from the month pillar. A useful sentence names the season or the 10-year stretch and the tendency to watch. A wedding date, a diagnosis, a verdict, or a price stays on the record that already holds it.

How to turn a prediction into a useful reflection keeps a calculated pillar separate from a life claim you can check later.

How do you bring a question to a BaZi chart?

Bring a birth date, the best-known clock time, and one sentence with four parts: the background you know, the options that are open, the time range, and the judgment you want. The sentence shape is in how to turn a vague worry into a question a reading can answer. An uncertain hour stays written as a range. The date, the clock, and a nearby solar term are listed in what birth information a reading needs.

A personal reading calculates the four pillars from those inputs and keeps the Month Command on the page with the temperament paragraph. To keep a reading for two years and ask follow-up questions on the same chart, see pricing.
