Numerology: two systems, Chaldean and Kabbalistic
Ollin calculates numerology with two distinct systems. The Chaldean system assigns values to letters based on their sound. The Kabbalistic system reads them through the ten Sephirot of the Tree of Life. They give different numbers for the same name, and that's exactly as it should be: they're two keys, not two measurements of the same thing.
Two systems, not two versions
The first thing to clear up is also what causes the most confusion: Chaldean and Kabbalistic aren't two names for the same technique, and one isn't a refined version of the other. They use different value tables, so the same name produces different numbers in each system.
Chaldean numerology · why Chaldean and not Pythagorean
The Pythagorean method, the one you'll find everywhere, assigns 1 to A, 2 to B and so on up to 9, then starts over. It's simple and arbitrary: it assumes the order of the Latin alphabet carries meaning.
The Chaldean method starts from sound. Letters with a similar vibration get the same number, wherever they sit in the alphabet, and 9 is never assigned to a letter because it's considered sacred. It's more laborious and less intuitive, but it has the longest tradition behind it, and it's the one Ollin uses.
The four core numbers
Ollin calculates both the reduced number and the compound number, the one you get before the final reduction. In the Chaldean tradition the compound number matters as much as the reduced one, sometimes more: it shows how you came to be who you are, not just who you are.
Cycles: where you are right now
This is the part that makes numerology useful day to day, rather than a static description. Crossing your birth date with today's date produces three nested levels.
- Personal Year: a nine-year cycle in which you plant in a 1 year, harvest in an 8 and close things out in a 9
- Personal Month: the theme of the month within your year
- Personal Day: the mood of the day, which is also what powers your morning email
On top of these come the Pinnacles and Challenges: four major phases that span your whole life, each with its own growth theme and its own recurring friction. Ollin calculates which one is active for you right now and how much time it has left.
Karmic debts and karmic lessons
Karmic lessons are read through absence: they're the numbers that never appear in your full name. If a vibration is missing entirely, tradition says that's exactly where life will test you most often.
Karmic debts, on the other hand, show up in compound numbers: certain combinations point to a theme that keeps coming back until you work through it. Ollin calculates and names them, but presents them for what they are: a symbolic lens, not a life sentence.
Kabbalistic numerology · numbers on the Tree of Life
The second system applies a Pythagorean-style gematria to the Latin alphabet (three cycles of nine, from A to Z) and then does something Chaldean numerology doesn't: instead of stopping at the number, it uses it as a coordinate. Each result lands on one of the ten Sephirot of the Tree of Life, and the reading is that of the Sephirah where it landed.
For your dominant Sephirah, Ollin shows the pillar it belongs to, its essence, its challenge, and its correspondences in the Hermetic tradition: planet, archangel, Divine Name, chakra, color, stone. It also shows the Qliphah, the shadow side of the same Sephirah: the form that quality takes when it hardens.
Every number comes with its calculation spelled out, letter by letter: D(4)+A(1)+R(9)… = 71 → 8. Not out of pedantry, but because a number without its math is a black box, and you can't even disagree with a black box.
Your Hebrew birth date
The Kabbalistic section also holds the least symbolic and most verifiable part of all of Ollin: your birth date converted to the Hebrew calendar, with the name of the month, the observance that fell on that day, and the parashah (the Torah portion) for that week. It's a calculated calendar, not an interpretation.
What's tradition and what isn't
Here we'd rather be precise, even if it costs us some mystique. What circulates as "Kabbalistic numerology" is a modern system: a Pythagorean gematria applied to the Latin alphabet, whose results are then read through the Sephirot and the correspondences of Western Hermetic Qabalah.
The name you use matters
Both systems work from your full birth name, the one on your birth certificate. If you usually go by a nickname or have changed your last name, the numbers change: they're different readings, and they can coexist.
In Ollin you can ask about this directly in the chat, in your own words, for example "what changes if I use the name everyone calls me?", and get a comparison calculated on both versions.
