What is a life path number, and where does it come from?

A life path number is the single number a birth date adds up to in numerology. Reduce the month, the day and the year to one digit each, add the three, and reduce again. Most dates land on 1 to 9; about one in ten lands on a master number, 11, 22 or 33, which is kept whole.

What a life path number is

Numerology is the old idea that numbers carry meaning beyond counting. Its best-known number is the life path, the sum of a birth date shrunk to a single number. Because a birthday never changes, numerologists treat it as the fixed number in a chart, the one you were handed rather than the ones you can change, like a name. 1

There are twelve possible answers. Nine are the single digits, 1 to 9. The other three, 11, 22 and 33, are master numbers: when a sum lands on one of them, numerologists stop adding instead of shrinking it to 2, 4 or 6. 2

If you know astrology, think of the life path as numerology's sun sign. It is the headline number, but a full numerology chart has others, worked out from the letters of your full name and from the year you are in. 2

Writers have never agreed on a name for it. The same sum appears in books as the birth number, the birth path, the fate number, the astral number and the life path number. The machine uses life path because that is what most people search for. 1,3

How it's worked out

Three numbers in, one number out. Here is one birthday, every step shown.

The path, worked outNovember 29, 1987
  1. Month November 11 11 kept whole
  2. Day 29th 29 2 + 9= 11 11 kept whole
  3. Year all four digits 1987 1 + 9 + 8 + 7= 252 + 5= 7 7  
Add the three 11 + 11 + 7 = 29 2 + 9= 11
Life Path 11 a master number, kept whole
  1. Write the birth date as three numbers: month, day and year. November 29, 1987 is 11, 29 and 1987.
  2. Shrink each one to a single digit by adding its digits, and keep going until one digit is left. The one exception: if you land on 11, 22 or 33, stop. November is month 11, so it stays 11. The 29th becomes 2 + 9 = 11, so it stays 11 too. The year 1987 becomes 1 + 9 + 8 + 7 = 25, then 2 + 5 = 7.
  3. Add the three results and shrink the total the same way: 11 + 11 + 7 = 29, and 2 + 9 = 11. A master number again, so it stays. November 29, 1987 is Life Path 11.
  4. Reducing the month, the day and the year separately is the method most modern numerologists use, and it is the one the machine uses. It matters, because the order of adding can decide whether a master number ever appears. Add all eight digits of this date in one go and you get 38, then 11, the same answer; for plenty of other dates the two methods part company. 2,1

Why 11, 22 and 33 are kept whole

Why keep 11, 22 and 33? Not for arithmetic reasons. L. Dow Balliett, who set the rules down in 1908, believed numbers were vibrations and that these few were higher ones: in a birth number they meant 'a master came with you when born'. Her own list was 8, 9, 22 and 11. Later writers dropped 8 and 9, and in 1930 Ariel Yvon Taylor added 33. 3,4

What the rule does to the numbers is easy to measure. Every total that would have become 2 by way of 11 stops at 11 instead, so 2 is the rarest of the single digits. Likewise 22 takes a share that would have been 4, and 33 a share that would have been 6.

Underneath it all sits a piece of school arithmetic. Adding up the digits of a number leaves the same remainder on division by 9 as the number itself, the old bookkeepers’ check called casting out nines. Take the master numbers out, and every life path is just what is left when the date’s digits are divided by 9, with 9 standing in for nothing left over.

Four things most people don't know

Where it comes from

From Pythagoras to your phone, era by era, with sources. The longer version is in the Reading Room.

  1. Ancientc. 570–490 BCEPythagoras lives on Samos and later at Croton in southern Italy. He writes nothing, so everything said about him, including his supposed numerology, comes from other people, most of it centuries later. 5
  2. Classical4th century BCEAristotle describes the 'so-called Pythagoreans', who held that the principles of numbers were the principles of all things, and who tied justice, soul and opportunity to particular numbers. 6
  3. Classicalc. 100 CEPlutarch records that the Pythagoreans called five 'Marriage', the union of the first male number, 3, with the first female, 2. 7
  4. Classical1st century CEGreek letters are numbers too. Suetonius quotes a Roman joke against Nero: his name, in Greek letters, adds up to the same 1005 as a phrase accusing him of killing his mother. 8
  5. Late antiquec. 200 CEThe word gematria first appears in a list of rules for reading scripture. In Hebrew, letters double as numerals, so any word has a total, and gematria reads words through those totals. 9
  6. Late antique3rd–6th centuryThe Sefer Yetzirah, the Jewish book of creation, describes the world as made through 32 paths of wisdom: ten Sefirot and the 22 letters of the alphabet. Later Kabbalah builds on it. 10
  7. 1900s1908L. Dow Balliett of Atlantic City publishes The Philosophy of Numbers. Her worked example, a man born January 17, 1872, reduces the month, the day and the year and adds them: the same steps used today. She keeps 11 and 22 whole as master numbers. 3
  8. 1900s1898–1908Juno Jordan starts studying with Balliett in 1898, at fourteen. She lives until 1984, so a single student links Balliett’s Atlantic City of the 1900s to the numerology paperbacks of the 1980s. 4
  9. 1920s1926Cheiro, the pen name of Count Louis Hamon, publishes his Book of Numbers in London. He uses the day of the month alone as the birth number and gives each digit a planet. 11,4
  10. 1930s1930Ariel Yvon Taylor's Numerology Made Plain lists 11, 22 and 33 as master numbers, one more than Balliett. 4
  11. 1930s1931Florence Campbell's Your Days Are Numbered: A Manual of Numerology for Everybody is published in New York. It is still in print fifty years later. 12,4
  12. 1960s1965Juno Jordan, who began studying with Balliett as a teenager, publishes Numerology: The Romance in Your Name. Her California Institute of Numerical Research met weekly for 25 years. 4
  13. 1970s1979Numerology and the Divine Triangle, by Faith Javane and Dusty Bunker, comes out from Para Research: one of a wave of paperbacks that took the birth-date sum to bookshop shelves. 13
  14. 2010s2017Psychologist Jeremy Genovese tests birth numbers against every Nobel Prize winner from 1901 to 2010 and finds them spread no differently from chance. 1
  15. Today2020sNumerology lives on phones. By 2023 the #AngelNumbers hashtag on TikTok, a numerology offshoot, was reported to have hundreds of millions of views, and NBC’s TODAY publishes a guide to calculating your life path. 14,15

Questions people ask

What is a life path number?

A life path number is the single number a birth date adds up to in numerology. Reduce the month, the day and the year to one digit each, add the three, and reduce again. Most dates land on 1 to 9; about one in ten lands on a master number, 11, 22 or 33, which is kept whole.

How do I work out my life path number?

Reduce the month, the day and the year of your birth to one digit each by adding their digits, keeping 11, 22 and 33 whole. Add the three results and reduce the total the same way. November 29, 1987 is 11, 11 and 7, which add up to 29, and 2 + 9 = 11.

Life path calculator

Why are 11, 22 and 33 not reduced?

Tradition, not arithmetic. L. Dow Balliett, whose 1908 book set down the method, treated certain numbers as higher vibrations and called them master numbers. Her list was 8, 9, 22 and 11; later writers kept 11 and 22, and Ariel Yvon Taylor added 33 in 1930.

What a master number is

Which life path number is the rarest?

33, at about 0.9% of birthdays from 1950 to 2009, then 22 at 3.1%. Among the single digits, 2 is rarest at 4.6%, because totals that would reach 2 by way of 11 stop at 11.

Did Pythagoras invent numerology?

No. Pythagoras wrote nothing, and the number lore credited to him reaches us through Aristotle and much later writers. The Pythagoreans did tie ideas like justice and marriage to numbers, but the birth-date sum is first found in print in 1908.

The full history in the Reading Room

Is the life path the same as a birth number or destiny number?

Usually, yes: writers have used birth number, birth path, destiny number and life path for the same birth-date sum. Be careful with old books, though. Cheiro, in 1926, used the day of the month alone as the birth number, and some modern books use destiny number for the number of your name.

Is there any evidence numerology works?

The one direct test we found, a 2017 study of every Nobel Prize winner from 1901 to 2010, found their birth numbers spread no differently from chance. Numerology is a tradition, read for fun and reflection, not a science.
