Chaldean or Pythagorean: Why Name Numerology Disagrees
Two practitioners, two different numbers for the same name. Both letter charts set out in full, why the results differ, which spelling of your name is actually used, and what to ask before paying for a name analysis.
By Dr. Kimaya Parikh-Ambekar, Vastu consultant, Andheri East, Mumbai
01
Why two practitioners give different answers
Birth-date numerology is largely consistent between schools. Name numerology — नामांक (namank) — is not, and the disagreement is not a matter of skill — it is that two different letter charts are in use.
If you have been given two different numbers for your own name, the first question is not which practitioner is right. It is which system each of them used.
02
The Pythagorean chart
Pythagorean, the system more common in Western practice, is the simpler of the two. The alphabet is numbered 1 to 9, then repeats.
It is straightforward enough to apply yourself.
- 1 — A, J, S
- 2 — B, K, T
- 3 — C, L, U
- 4 — D, M, V
- 5 — E, N, W
- 6 — F, O, X
- 7 — G, P, Y
- 8 — H, Q, Z
- 9 — I, R
03
The Chaldean chart
Chaldean is older, more common in Indian practice, and does not follow the alphabet. Values are assigned by the sound of the letter, and 9 is not assigned to any letter at all, being traditionally treated as sacred.
The commonly used chart runs as follows, though minor variations appear between sources.
- 1 — A, I, J, Q, Y
- 2 — B, K, R
- 3 — C, G, L, S
- 4 — D, M, T
- 5 — E, H, N, X
- 6 — U, V, W
- 7 — O, Z
- 8 — F, P
- 9 — not assigned to any letter
04
The same name, both ways
Take the name KIRAN. In Pythagorean: K is 2, I is 9, R is 9, A is 1, N is 5. The total is 26, which reduces to 2 + 6 = 8.
In Chaldean: K is 2, I is 1, R is 2, A is 1, N is 5. The total is 11, which in Chaldean practice is usually kept as a compound number and read as 11, or reduced to 2 depending on the practitioner.
Eight and two carry quite different readings. Neither calculation is a mistake; they are answers to the same question from two different systems.
05
Which spelling of your name is used?
This matters more than the choice of system and is asked about far less often.
Most practitioners work from the name you actually use and are known by day to day, rather than the full legal version on a birth certificate that nobody calls you. If you are Priya to everyone but Priyadarshini on your passport, those produce different numbers, and the practitioner should tell you which they have used and why.
Nicknames, married surnames, initials and anglicised spellings all raise the same question. There is no universal rule, which is precisely why you should ask.
06
Before you pay for a name analysis
Name numerology is the area of this field where the most money is spent and the most pressure is applied, usually in the form of a recommended spelling change.
A few questions sort a careful practitioner from a careless one, and they are reasonable to ask of anyone, including us.
- Which system are you using, Chaldean or Pythagorean, and why that one?
- Which spelling of my name are you working from?
- Are compound numbers kept or reduced in your reading?
- What exactly am I getting, and what does it cost in total?

On changing the spelling of your name
You will encounter the suggestion. Treat it carefully, and never under pressure.
Changing a name spelling has real consequences — bank records, passports, degrees, property documents, visas — and in India the paperwork is not trivial. No reading should move you towards that in a single consultation, and nobody should charge a large fee to supply a corrected spelling alongside a warning about what will happen if you do not adopt it.
A number is not a diagnosis, and no practitioner should use one to create fear. If you are being frightened, the problem is the practitioner.
Consultations here are online, anywhere in India or abroad, and the first call is free. You will be told which system is being used before anything is calculated.
Questions
Frequently asked
What is the difference between Chaldean and Pythagorean numerology?
Pythagorean numbers the alphabet 1 to 9 in order and repeats. Chaldean assigns 1 to 8 by the sound of the letter rather than alphabetically, and does not assign 9 to any letter.
Which numerology system is more accurate?
Neither is demonstrably more accurate; they are different systems with different charts. What matters is that a practitioner tells you which one they use and applies it consistently.
Which spelling of my name should be used?
Usually the name you are actually known by day to day rather than a longer legal version. Ask your practitioner which spelling they used, because it changes the result.
Why is 9 not used in Chaldean numerology?
In Chaldean practice 9 is traditionally treated as sacred and is not assigned to any letter, though it can still appear as a total.
Should I change the spelling of my name based on numerology?
Be very cautious. It affects bank records, passports, degrees and property documents, and no responsible practitioner will push you towards it in a single sitting or charge heavily for a corrected spelling.
