Life path number calculator

The life path number calculator from API for Astrology (apiforastrology.com) finds your life path number from a birth date. The full name you enter gives three more numbers: expression, soul urge and personality. Master numbers 11, 22 and 33 keep their two digits instead of being reduced to one.

The life path is the Western number that comes from the whole birth date. Expression uses every letter of the name, soul urge the vowels and personality the consonants. We do not store the details you enter.

How the life path number is worked out

The life path adds up the birth date in three parts. The month, the day and the year are each reduced first. Reducing means adding the digits until one digit is left. A part that comes to 11 or 22 is kept as it is. Then the three parts are added and reduced again. Adding all the digits at once gives the same single digit. But the two ways can differ on master numbers.

The name numbers use the Pythagorean letter values. A is 1, B is 2, C is 3, up to I at 9. Then J starts again at 1. Each word of the name is reduced before the words are added. Y counts as a vowel when neither letter beside it is a vowel. W always counts as a consonant.

The same POST /v1/western request, with your own API key, returns all of this as JSON. It also returns the maturity number, karmic lessons, the pinnacles and the personal year.

Worked example: John Doe's life path

John Doe was born on August 15, 1990. He gets 8 for the month and 6 for the day, since 1 + 5 = 6. The year gives 1 + 9 + 9 + 0 = 19, then 1 + 9 = 10, then 1 + 0 = 1. The parts make 8 + 6 + 1 = 15, and 1 + 5 = 6. So his life path is 6.

Adding every digit at once gives 33, a master number. So a book that adds all the digits would call him a 33. The API adds the three parts, so it returns 6. That is why two calculators can give different life paths for the same date.

Method and sources

Every number here comes from simple counting on the name and date you enter. So the same details always give the same result. The letter values and the counting rules are on the numerology conventions page.

The life path reduces the month, the day and the year one by one, then adds them. The same steps appear in L. Dow Balliett's The Philosophy of Numbers (1908). The Pythagorean letter values, 1 to 9 in alphabet order, match the table in L. Dow Balliett's The Philosophy of Numbers (1908).

Common questions

All questions
Why is my life path different from my mulank?

The life path is a Western number from the whole birth date. The mulank is an Indian number from the day alone. Jane Doe, born March 22, 1992, has mulank 4 but life path 1. The numerology calculator shows the Indian numbers.

Find your mulank
What are master numbers?

In Western numerology, 11, 22 and 33 are called master numbers. When a sum lands on one of them, the tool keeps it instead of adding its digits. The API returns the master number in number, with the single digit beside it in digit. Your app can show either.

Master numbers in the glossary
Does Y count as a vowel?

Sometimes. Y counts as a vowel when neither letter beside it is a vowel, as in Lynn or Mary. In Maya or Ray it counts as a consonant. W always counts as a consonant. This changes the soul urge and personality numbers, so the API states the rule in its answer.

What the soul urge number is
Which name should I enter?

Enter the full name from birth, as the API asks. The expression, soul urge and personality numbers use every word of the name. A nickname or a married name can give different numbers. Write the name in English letters (A to Z).

Can I add a life path calculator to my own app?

Yes. Sent with your own API key, POST /v1/western returns every Western number as JSON, each with a short reading. That includes the pinnacles with their ages and years. It also gives the personal year, month and day for the date in as_of. One live call uses 3 reading credits.
