Life Path Numbers: How to Work Yours Out and What Each One Means

The life path number is the best known number in Pythagorean numerology. It comes from a date of birth and nothing else, and the tradition treats it as a description of the main themes a person is invited to work with, not as a forecast. This page shows exactly how the number is worked out, including the places where two sensible methods disagree, and then links to a separate guide for each number.

How the life path number is worked out

The method used on this site, and in our life path number calculator, has four steps:

1. Reduce the month to a single digit by adding its digits.
2. Reduce the day in the same way.
3. Reduce the year in the same way.
4. Add the three results and reduce the total once more.

To reduce a number, add its digits. If the answer still has two digits, add those, and repeat until one digit is left. The one exception is explained under master numbers below.

One fully worked example

Take a date of birth of 9 October 1991.

• Month: October is month 10, and 1 + 0 = 1.
• Day: 9 is already a single digit, so it stays 9.
• Year: 1 + 9 + 9 + 1 = 20, and 2 + 0 = 2.
• Add the three: 1 + 9 + 2 = 12.
• Reduce the total: 1 + 2 = 3.

The life path number for 9 October 1991 is therefore 3. Nothing in the working involves judgement, so anyone who follows the steps gets the same answer, and that is worth keeping in mind: the arithmetic is exact, while the meaning attached to the result is a matter of tradition.

The second method, and why it can differ

Many calculators use a shorter route. They add every digit of the whole date in one go and then reduce. For 9 October 1991 that is 9 + 1 + 0 + 1 + 9 + 9 + 1 = 30, then 3 + 0 = 3. The two methods agree here, and for most dates they do.

They can disagree because reducing each part first throws away the intermediate totals. Take 20 January 1990:

• Separate parts: January is 1, the 20th reduces to 2, and 1990 gives 1 + 9 + 9 + 0 = 19, then 1 + 9 = 10, then 1. The sum is 1 + 2 + 1 = 4.
• All digits at once: 1 + 9 + 9 + 0 + 0 + 1 + 2 + 0 = 22, which is a master number.

So one method gives 4 and the other gives 22. A second example is 14 March 1987, which gives 6 by the separate method and 33 by adding all the digits (1 + 9 + 8 + 7 + 0 + 3 + 1 + 4 = 33). Neither method is the only correct one, and different books and teachers prefer different ones. Our calculator tells you when your date is affected, so you can read the guides for both numbers if you wish.

Master numbers

Numbers made of a repeated digit, 11, 22 and 33, are treated by many numerologists as master numbers. Instead of adding them down to 2, 4 and 6, the practice is to stop at them and read them as a separate, more demanding version of the smaller number. Master numbers are a fairly modern addition to numerology and not part of the oldest Pythagorean material, and some numerologists do not use them at all.

In our method a master number is kept wherever it appears: as the reduced month (November is 11), the reduced day (the 11th, the 29th, which gives 2 + 9 = 11, or the 22nd), the reduced year (1975 gives 1 + 9 + 7 + 5 = 22), or the final total. The calculator has a box to reduce masters to a single digit if you prefer that convention. For a master number date, the guide for the single digit is worth reading too, since the traditions treat the master as that number with more weight on it. For example, a life path of 22 is read alongside the life path 4 guide.

• Life path number 7
• Life path number 8
• Life path number 9
• Life path number 11
• Life path number 22
• Life path number 33

How to read these guides

Each guide describes what the tradition associates with the number, with strengths and growth edges set side by side, because every number is described as having both. None of it is scientific, and no study has shown that a number derived from a birth date describes personality or predicts anything. The guides are written as a prompt for reflection: read the description, notice what feels true and what does not, and discard the rest. If you want the two letter systems used for names, see the Pythagorean and Chaldean explainer.
