How to Calculate Your Life Path Number

Your life path number comes from your date of birth, and you can work it out with a pencil in about a minute. This guide explains the standard method, shows three complete examples, and covers the mistakes that cause most wrong answers. If you would rather skip the arithmetic, the life path calculator does it instantly and prints every step.

What you need

Only your full birth date: the month, the day, and the four-digit year. Nothing about your name, birth time, or birthplace is used. The whole procedure is one idea repeated: add the digits of a number together until you reach a single digit. Numerologists call this reducing a number.

The method, step by step

This is the separate-reduction method, which keeps Master Numbers visible and is the one used on this site.

1. Reduce the month. January through September are already single digits. October is 1 + 0 = 1, November stays 11, and December is 1 + 2 = 3.
2. Reduce the day. Add its digits until one digit remains. The 28th becomes 2 + 8 = 10, then 1 + 0 = 1. The 11th and 22nd are kept as they are.
3. Reduce the year. Add all four digits of the year, then keep reducing. For 1990 that is 1 + 9 + 9 + 0 = 19, then 1 + 9 = 10, then 1 + 0 = 1.
4. Add the three results. Month plus day plus year gives one total.
5. Reduce the total. If it is more than one digit, add its digits again. Stop at a single digit, or at 11, 22, or 33.

The Master Number exception

Whenever 11, 22, or 33 appears, whether as the reduced month, day, or year, or as the final total, you do not reduce it further. That is the only exception in the method. It matters in two places: a Master Number can feed into the total (an 11 for a November birth adds 11, not 2), and if the last sum comes out as 11, 22, or 33, that is your answer. You can read about what each one means on the pages for Life Path 11, Life Path 22, and Life Path 33.

Example 1: a birth date that gives 11

September 28, 1990 shows the exception at work. Every line below was produced by the same engine that powers the calculator.

The total is 9 + 1 + 1 = 11. That is a Master Number, so the process stops and the answer is 11 rather than 2.

Example 2: a birth date that gives 22

April 27, 1998 lands on a different Master Number and also happens to be a date where the two common methods disagree.

The month is 4, the day 2 + 7 = 9, and the year 1 + 9 + 9 + 8 = 27, then 2 + 7 = 9. The total is 4 + 9 + 9 = 22, which stays as 22. The one-step check underneath adds all eight digits at once and arrives at 4, the base digit of 22.

Example 3: an ordinary single-digit result

Most birth dates do not touch a Master Number at all. March 17, 1985 is typical.

Here the total is 3 + 8 + 5 = 16, which reduces to 1 + 6 = 7. Both methods agree, so there is nothing to reconcile.

The one-step method

Some calculators skip the separate reductions. They write the date as MMDDYYYY, add all eight digits in one go, and reduce that single sum. For September 28, 1990 that is 0 + 9 + 2 + 8 + 1 + 9 + 9 + 0 = 38, then 3 + 8 = 11. For April 27, 1998 it is 0 + 4 + 2 + 7 + 1 + 9 + 9 + 8 = 40, then 4 + 0 = 4.

When the two methods disagree

Adding digits never changes a number's remainder when divided by nine, which means both methods always end on the same base digit. They can differ only in whether the answer is a Master Number. In April 27, 1998 the separate method reaches 22 on the way and keeps it, while the one-step method has no reason to stop at 22 and carries on to 4.

Counting every calendar date from 1950 to 2010, about 13% of birth dates get a different answer from the two methods. That is why a friend may quote you a different number from a different website, and why this site's calculator shows the one-step result next to the main one.

There is no authority that settles which method is right. Both are conventions. This site uses separate reduction because it keeps Master Numbers visible.

Common mistakes

• Reducing 11, 22, or 33 too early. Turning an 11 month into a 2 before adding changes the total. Keep Master Numbers until the very end.
• Dropping a digit of the year. All four digits count. 1990 is 1 + 9 + 9 + 0, not just 9 + 0.
• Using a two-digit year.'90 is not the same as 1990. The full year is needed.
• Swapping day and month. A date like 04/05/1992 means April 5 in the U.S. and May 4 in much of the world. Write the month name out before you start.
• Stopping one step early. A total of 16 is not a life path number. Reduce it to 7.
• Treating an 11 month as an 11 life path. Only the final total decides whether you are a Master Number.
