Elon Musk's BaZi Chart: Pillars, Cycles, and Turning Points
Elon Musk's four pillars, both circulating birth times, six luck cycles, his partner star, and the decade opening in 2028, read the traditional way.
Celebrity chart readings tend to start at the conclusion and work backwards. This page does the welding, and shows the work.

Key takeaways (~30 sec)
- On the most-cited birth time, Musk's chart is 辛亥 year, 甲午 month, 甲申 day, 戊辰 hour, with 甲 Yang Wood as the Day Master.
- Three pillars come from the birth date and are certain. The hour is not, and the two circulating times produce different hour pillars.
- His zodiac animal did not change when he left South Africa. The year pillar is fixed at birth.
- What moves across a life are the luck cycles, which need the birth year's polarity rather than the birth hour.
- The public record is set against those cycles here, in the way a traditional reading would set it, along with the partner star and the decade now opening.
The chart on the most-cited birth time
| Pillar | Heavenly Stem | Earthly Branch |
|---|---|---|
| Year | 辛 Xīn, Yin Metal | 亥 Hài, the Pig branch, Water |
| Month | 甲 Jiǎ, Yang Wood | 午 Wǔ, the Horse branch, Fire |
| Day | 甲 Jiǎ, Yang Wood (Day Master) | 申 Shēn, the Monkey branch, Metal |
| Hour | 戊 Wù, Yang Earth | 辰 Chén, the Dragon branch, Earth |
The Day Master is 甲, Yang Wood, and the month stem repeats the same character, so the same element stands at the top of the chart twice. The month branch 午 carries Fire, and Wood feeds Fire, which spends it. The year stem 辛 and the day branch 申 both carry Metal, and Metal controls Wood. The year branch 亥 carries Water, and Water feeds Wood. One drain, two pressures, one support.
The element tally for this date is easy to reproduce: Wood 2, Fire 1, Earth 2, Metal 2, Water 1. A reader who enters 28 June 1971 with 07:30 as the hour gets the same eight characters and the same count back.
That is the grid. It describes a set of relationships between eight characters, and it stops well short of describing a person.
Two versions of the hour
The first three pillars are fixed by the birth date, 28 June 1971, and they hold regardless of what else is uncertain. The hour pillar is the one that depends on a clock.
Two times circulate for Musk. The more common one, 07:30, appears in a biography, and no published birth record stands behind it. A second version, 06:30, appears in reference databases and other chart sites with no stated source either.
The gap between them is small on paper and large in the chart. 07:00 is the boundary between 卯 and 辰, so 07:30 falls in 辰 and 06:30 falls in 卯. Different branch, and because the hour stem is derived from the day stem, a different stem as well.
True solar time does not rescue the first one either. Pretoria sits about 1.8 degrees west of the meridian its clocks run on, which pulls the local sun time back by about seven minutes, and the time of year costs a few more. The reading lands near 07:20, still inside 辰, but the margin is minutes rather than hours.
So this page uses the 07:30 chart throughout and marks the hour column as unconfirmed. Anyone reading a site that presents it as settled is reading a guess dressed as data.
What the year pillar says, and what it does not
辛亥 is the year pillar: Yin Metal above, the Pig branch below, and the branch carries Water.
The year pillar is the slowest of the four. It turns once every twelve years, so it covers a very large group of people at once, and in a traditional reading it carries the widest and earliest layer of a chart. The month pillar sets the climate, the day pillar carries the Day Master, and the hour pillar carries the later stretch of a life.
辛亥 is also the pillar that gives Musk his zodiac animal, and the date it turns on is not the date most zodiac tables use. The Four Pillars year turns at 立春, the first solar term of spring. Popular zodiac tables turn it at Chinese New Year, and the two dates disagree by about a week each year. Musk was born in June, so both calendars give him the same animal.
The animal on its own, with the compatibility pairs, is a shorter read.
The move that changed nothing
Musk left South Africa for Canada in 1989, later studied in the United States, and became a US citizen in 2002. Three countries, one year pillar.
That is not a technicality. The year pillar is set by the moment of birth and does not move afterwards. A passport is not an input to the calculation, and neither is a change of address.
Geography enters a chart in one place only, and it is not the year. True solar time shifts the boundary between hour branches according to the birth city's distance from its time zone meridian. That can move the hour pillar. It cannot move the year pillar.
So when a reading says a move changed someone's sign, one of two things is happening.
Either the writer is describing the popular zodiac, which turns at Chinese New Year and disagrees with the Four Pillars year pillar for anyone born in the gap. Or the writer has confused the year pillar with the luck cycles, which is the subject of the next section.
What shifts instead: the luck cycles
The luck cycles are ten-year periods layered over a chart. They are the part of a reading that changes with time, which makes them the natural place for a story about a life changing shape.
The sequence runs forwards or backwards from the month pillar, and the direction comes from two inputs that have nothing to do with the hour: the polarity of the birth year's stem and the person's gender. 1971 carries 辛, a Yin stem, and the standard rule sends a male chart backwards.
| Cycle | Ages | Approximate years |
|---|---|---|
| 癸巳 Guǐ Sì | 7 to 17 | 1978 to 1988 |
| 壬辰 Rén Chén | 17 to 27 | 1988 to 1998 |
| 辛卯 Xīn Mǎo | 27 to 37 | 1998 to 2008 |
| 庚寅 Gēng Yín | 37 to 47 | 2008 to 2018 |
| 己丑 Jǐ Chǒu | 47 to 57 | 2018 to 2028 |
| 戊子 Wù Zǐ | 57 to 67 | 2028 to 2038 |
The first cycle starts at about age seven. The standard reckoning counts three days from the preceding solar term to one year of life, and the preceding term here is 芒种, Grain in Ear, which fell on 6 June 1971. The birth date sits about twenty-two days past it.
Note what the table does not depend on. The order of the cycles is fixed by the month pillar, and the start age moves by a handful of days between the two candidate birth times. The hour problem that wrecks the fourth pillar does not touch this table.
Reading the six cycles
Each cycle pairs a stem with a branch and lays the pair over ten years. The tradition reads that stem through the Ten Gods, which measure it against the Day Master and hand the relationship a name.
甲 is Yang Wood. Each stem in the sequence is measured against it, and the six cycles map onto the Day Master like this.
| Cycle | Stem | Against 甲 Yang Wood | Branch carries |
|---|---|---|---|
| 癸巳 | 癸 Yin Water | 正印 Direct Resource, Water feeding Wood | 巳, Fire |
| 壬辰 | 壬 Yang Water | 偏印 Indirect Resource, the same feed from the side | 辰, Earth |
| 辛卯 | 辛 Yin Metal | 正官 Direct Officer, Metal trimming Wood | 卯, Wood |
| 庚寅 | 庚 Yang Metal | 七杀 Seven Killings, the same cut with nothing holding it back | 寅, Wood |
| 己丑 | 己 Yin Earth | 正财 Direct Wealth, Wood spending itself on Earth | 丑, Earth |
| 戊子 | 戊 Yang Earth | 偏财 Indirect Wealth, the same spend at a distance | 子, Water |
The shape of the ladder is worth pausing on. Two Resource decades open it, and Resource is what feeds the Day Master. Two Metal decades follow, and Metal is what trims it. Two Wealth decades close it, and Wealth is what the Day Master spends itself on. Fed, trimmed, spent.
That shape is set the moment the month pillar is set. It does not wait on a birth hour, because the Ten Gods are read against the day stem and the day pillar comes from the date.
The star that names a partner
The tradition reads partnership through Wealth, which is the element the Day Master controls. 甲 is Yang Wood and Wood controls Earth, so 戊 and 己 are his Wealth stars. 己 Yin Earth is 正财, Direct Wealth, the settled partner. 戊 Yang Earth is 偏财, Indirect Wealth, the partner who comes in from outside the expected line.
This chart holds both, and it holds them late.
戊 sits in the hour pillar. The hour covers the back half of a life, so the 偏财 resting there is a Wealth star with a long fuse on it. The last two cycles carry the rest. 己丑, running from 2018, arrives with 正财 as its stem. The 戊子 decade opening in 2028 arrives with 偏财. Two Wealth decades, one behind the other, closing the ladder.
The spouse palace is the day branch, and here it holds 申: Monkey, Metal. 申 carries three stems, 庚, 壬 and 戊, which read against a Yang Wood Day Master as 七杀, 偏印 and 偏财. The position the tradition assigns to the partner therefore holds a Wealth stem, a Resource stem and an Officer stem at once.
The tradition runs Wealth into Officer: Earth produces Metal, so a Wealth star feeds the Officer star. Two Wealth decades in the back half of the ladder read as feeding the standing they run beside.
The record, read beside the cycles
Here is the public record, the cycle running at the time, and the way a traditional reading would place the two together.
| Public record | Cycle in force | How a reading places it |
|---|---|---|
| 1989, leaves South Africa for Canada | 壬辰, one year in | 偏印 is the resource found away from home, the mark of a decade spent acquiring elsewhere |
| 1995, founds Zip2 | 壬辰, seven years in | 偏印 again: the indirect route, technical and self-taught rather than appointed |
| 1999, sells Zip2 | 辛卯, one year in | 正官 arrives, and with it the first transaction that turned work into standing |
| 2002, founds SpaceX and becomes a US citizen | 辛卯, four years in | 正官 is the officer, and both events are about formal station: a company and a citizenship |
| 2004, leads Tesla's first outside investment | 辛卯, six years in | 正官 again: the office arrives with the money |
| 2008, Falcon 1 reaches orbit and he takes over as Tesla's chief executive | 庚寅, first year | 七杀, the officer with nothing holding it back. The year both companies nearly ended |
| 2012, Dragon docks with the International Space Station | 庚寅, four years in | the same pressure, now producing firsts instead of near-exits |
| 2015, Falcon 9 lands for the first time | 庚寅, seven years in | pressure held long enough to become routine |
| 2020, Crew Dragon carries people | 己丑, two years in | 正财, the decade of the thing itself: production, delivery, a product that ships |
| 2022, acquires Twitter | 己丑, four years in | 正财 again, the plainest Wealth act on the list |
The 庚寅 line is the strongest in the table. Those ten years read as pressure taken head on, and the record inside them is a run of near-failures that turned into firsts. Seven Killings arriving as the cycle stem is the classic shape of a decade that decides whether the thing survives.
Ages seven to seventeen carry no entries. Those years are not on the public record, so the reading of 癸巳 stands on the stem and branch alone: Direct Resource, the first feed, laid down before there was anything built to feed.
The same ladder runs on your own chart, and reading it does not need anyone's birth hour. The direction rule takes the year's polarity and your gender; the Ten Gods take the day stem. Those two inputs produce the six windows.
The decade now opening
The 戊子 decade runs from 2028 to 2038, and it is the first cycle in the sequence whose branch stands opposite the month branch. 子 and 午 face each other across the compass, so this is a cycle that clashes a natal pillar.
The tradition reads a clash of that kind as a decade that disturbs whatever the pillar was doing. Here the pillar is the month, which carries the arena, the standing, and the stretch of life the chart says he was born into.
It does a second thing at once. 申 sits in the day pillar and 辰 sits in the hour pillar, and 子 with them makes 申子辰, the three-harmony combination of Water. Water produces Wood, so the same decade that clashes the month branch also completes a Resource combination across the day and hour.
戊 is Yang Earth and 子 is a Water branch, and Earth controls Water, so the 偏财 stem of the decade covers the branch it sits on. The Wealth star holds the surface while the Resource runs underneath.
For this chart the two readings sit together rather than closing each other out. A decade that moves the arena while feeding the Day Master is read as a decade of rebuilding somewhere else.
The window is on the calendar. What it holds is read, not scheduled.
Where the reading lands
Six ten-year windows cover the fifty-five years in that table. Each step is checkable: the pillars come from a date, the Ten Gods come from the day stem, the windows come from the month pillar and the year's polarity, and the clashes come from the branches themselves.
Run those steps on your own chart and the same ladder appears. It takes a birth date and your gender. It does not take anyone's birth hour.
Try it on a year. A man born in 1990 carries 庚, a Yang stem, so his cycles run forward from his month pillar. A woman born the same year runs them backward from the same pillar. One date, one month pillar, two directions, and the two ladders part company from the first decade.
FAQ
What is Elon Musk's BaZi chart? On the most-cited birth time it runs 辛亥, 甲午, 甲申, 戊辰: a Metal Pig year, a Wood Horse month, a Wood Monkey day, and an Earth Dragon hour.
What is Elon Musk's Day Master? 甲, Yang Wood, on the 28 June 1971 birth date. The Day Master is the stem of the day pillar, so it does not depend on the birth hour.
Is Elon Musk's birth time known? Not to a standard anyone can verify. The two circulating times sit on opposite sides of the 卯 辰 boundary, which changes the hour pillar and therefore the fourth column of the chart.
Would his zodiac sign change if he moved country? No. The year pillar is fixed by the birth moment. True solar time can move the hour pillar boundary, and it has no effect on the year.
What is the partner star in this chart? For a male chart the Wealth stars name the partner, and 甲 controls Earth. His 戊 sits in the hour pillar as 偏财, the 己丑 cycle brought 正财 from 2018, and the 戊子 cycle brings 偏财 from 2028. The spouse palace, the day branch, holds 申, which carries a Wealth stem as well as 庚, a Seven Killings.
What does the 戊子 decade hold? It runs from 2028 to 2038. Its branch clashes 午, the month branch, and it also completes the Water combination with 申 and 辰 that feeds a Yang Wood Day Master.
