‘Chaldean’ is the collective reference to the legends and lore from Babylon, Assyria and Sumer. The 11th dynasty of Babylon (6th century BC) is known as the Chaldean Dynasty.

Chaldean numerology is based around vibrations. Letters can be used to represent sound and these sounds produce vibrations and Chaldean numerology helps us understand the meaning of these vibrations.
Typically with Chaldean numerology, the letter mapping of the name is used to reveal life goals, personalities, desires and purpose. Chaldean analysis of birthdates reveals challenges and peaks in a life cycle and destiny.
Chaldean numerology uses the numbers 1 through 8. The number 9 is considered holy and kept separate from the main system. Letters are assigned to numbers based on their sound or vibration.
- 1 = A, I, J, Q and Y
- 2 = B, K and R
- 3 = C, G, L and S
- 4 = D, M and T
- 5 = E, H, N and X
- 6 = U, V and W
- 7 = O and Z
- 8 = F and P

Do you find Chaldean numerology is more helpful than Pythagorean? In Pure Spirit also has an interview with a master Chaldean numerologist.
Greetings friends,
The so-called “Chaldean” Numerology is not an ancient system of numerology but a (very) modern system which is inspired on the ancient qabalistic method of the “Aiq Bekar” (AIQ BKR) according to which the letters of the *HEBREW* alphabet correspond to the numbers from 1 to 9. So basically the “Chaldean” Numerology is an attempt to make our own alphabet fit into this originally hebrew system of Numerology. Also, the Aiq Bekar is nothing more than a hebrew version of the Pythagorian Numerology. And finally, the number 9 was never considered to be specially relevant in the Hebrew Aiq Bekar, and it was used like any other number.
In this system, the correlation between letters and numbers was made in the following way (using the names of the hebrew letters):
1= Aleph, Yod, Qoph
2= Beth, Kaph, Resh
3= Gimel, Lamed, Shin
4= Daleth, Mem, Tau
5= Heh, Nun
6= Vau, Samech
7= Zayin, Ayin
8= Cheth, Peh
9= Teth, Tzaddi
So as you can see, the number 9 was used, just like the numbers from 1 to 8. The only reason why 9 isn’t used in the modern pseudo-chaldean numerology is that the hebrew letters which corresponded to the number 9 didn’t originate any letter in our alphabet. For instance, the letter Teth (between CHETH / greek Eta / latin “H”, and YOD / greek Iota / latin “I” and “J”) doesn’t exist in our alphabet. Likewise, the letter Tzaddi (between PEH / greek Pi / latin “P”, and QOPH / obsolete greek Qoppa / latin “Q”) didn’t survive into our alphabet. So this is the reason why 9 isn’t used in the modern “Chaldean” Numerology. It has nothing to do with special “powers” of the number 9, nor even to any supposed “fear” of it from the “Chaldeans”.
Anyway… I’ve been making some investigations on alphabetical genealogy, and here’s the system I believe respects more the Aiq Bekar, and the connections between the hebrew/phoenician letters and the latin letters:
1= A, I, J, Q.
2= B, K, R.
3= C, G, L, S.
4= D, M, T.
5= E, N.
6= F*, U*, V*, W*, X**, Y*.
7= O, Z.
8= H, P.
* The hebrew letter Vau (=6) originated the obsolete greek letter Vau/Digamma (similar in shape to our “F”), and it is quite possible that it was the letter that inspired the creation of the greek letter Ypsilon (Y), the etruscan “U”, and the latin “U”/”V”. From U/V was created, much later, the letter W.
** The hebrew letter Samech (=6) originated the greek letter Xi (between Nu/N and Omikron/O) which, however, didn’t survive into our modern latin alphabet. However, it is quite possible that the greek letter Chi (between Phi and Psi) which originated our “X”, was taken from it. In fact, in some old italic alphabets, the shapes of these two distinct letters were very similar, perhaps showing a common origin.
Regarding the values of the letters F, H, X, Y in the modern pseudo-chaldean numerology, there isn’t any logic in:
-> giving “F” the value 8, since it derives (as shown) from the hebrew Vau (=6); this correspondence is partially understandable, however, since in hebrew the letter Peh can be read as either “P” or “F”, but even then there isn’t any relation between Peh/Pi/P (=8) and F;
-> giving “H” the value 5, since it has no relation at all to either Heh or Nun. The latin letter corresponding to hebrew Heh is “E”, not “H”. H was derived from Cheth (=8);
-> giving “X” the value 5 (no comment!);
-> giving “Y” the value 1, since it has no relation at all to the hebrew letter Yod. The latin letters corresponding to Yod are “I” (called “Iota” in greek) and “J” (called “Jot” or “Jota” in several languages).
So, here is again my proposal of the Genealogical System of Numerology (corrected “Chaldean” system):
1= A, I, J, Q.
2= B, K, R.
3= C, G, L, S.
4= D, M, T.
5= E, N.
6= F, U, V, W, X, Y.
7= O, Z.
8= H, P.
All the best,
Luís (Alektryon)
Dear Luis
Thank you so much for doing this. I've been interested and baffled by numerology since picking up a Linda Goodman book in the early 90's. You've made a lot of sense here and washed away so many inconsistencies. I'm going to recaluculate my name using your info.
Many Blessings To You
Nicola
Dear Nicola,
Many thanks for your kind words. However, don't accept my words as a proof of anything. Dig deep, do your own research, and through your own efforts confirm if what I wrote is true or not. If you discover it is, then use it according to your own will. And if it isn't… well, it was worth the try!
That was what I did… but fortunately I'm a human, and as such always subject to error! ;)
Warm regards from Portugal,
Luís Gonçalves
Great post!
If you’re looking for an indepth post on the compound numbers. I found one here that is very interesting.
