Your date of birth

The nine life paths

Every date of birth lands on one of these nine. Each has its own archetype and its own ruling planet.

How the number is worked out

Chaldean numerology reduces a date of birth in three parts, not one long sum. Add the digits of the day. Add the digits of the month. Add the digits of the year. Then add those three totals together and keep reducing until a single number from 1 to 9 remains.

26 September 1990 → day 2+6 = 8 · month 0+9 = 9 · year 1+9+9+0 = 19
8 + 9 + 19 = 36 → 3+6 = 9

That final number is your life path number. It describes what you are working toward: your goals, your drive, and how you meet the world.

It is not the same as your birth number, which comes from the day of the month on its own and describes the inner self — your natural personality and mindset. The two usually differ. Someone born on 26 September 1990 has a birth number of 8 and a life path of 9.

Cosmiclogy uses Chaldean numerology throughout — the older of the two common systems — so every number on this site is worked out the same way. Mixing systems is what produces two different answers for the same date.

Questions people ask

How do you calculate a life path number?
Add the digits of the day, the month and the year separately, add those three totals together, then keep adding the digits of the result until a single number from 1 to 9 remains. Born 26 September 1990: day 2+6=8, month 0+9=9, year 1+9+9+0=19. 8+9+19=36, and 3+6=9. The life path number is 9.
Is the life path number the same as the birth number?
No. The birth number comes from the day of the month alone and describes the inner self — personality and mindset. The life path number comes from the whole date of birth and describes what you are working toward. They usually differ.
What about master numbers 11, 22 and 33?
Cosmiclogy reads the life path as a single number from 1 to 9. Where a total lands on 11, 22 or 33, this calculator reduces it to its root — 11 reads as 2, 22 as 4, 33 as 6 — and tells you on screen that it did, so nothing is hidden from you.
Why Chaldean and not another system?
Chaldean is the older system and the one Cosmiclogy uses throughout, so every number on the site is calculated the same way. Mixing systems is what produces two different answers for the same date.
Does the life path number ever change?
No. It is fixed by your date of birth. A name can be changed and its numbers with it, but the date cannot — which is why the life path is treated as the steady thread underneath everything else.

One number is a doorway.

Your life path is a single thread. The full reading weaves it together with your birth chart and the rest of your numbers.
