Where the Chaldean Letter Values Come From
Chaldean numerology gives each letter a number from 1 to 8 based on the sound it makes, not its place in the alphabet. The letter values used today were set down by the numerologist Cheiro, born Count Louis Hamon, in his 1926 Book of Numbers.[1] They carry the name of the older Babylonian tradition that Cheiro credited as his source.
Here is the honest picture, and Naksham states it plainly. Reading a person through single digits 1 to 9 is a modern practice, written down in the early 20th century. The classical Sanskrit record, in texts like the Vedanga Jyotisha, treats Jyotisha as astronomy for timing rituals, with no digit numerology at all.[5] What the classical texts do hold is the next layer up. The planet, gemstone, colour, and mantra tied to each number come from classical sources. So a Chaldean name reading joins a modern number system to a classical planet-and-remedy layer, and Naksham cites each claim to the layer it truly comes from.
The Chaldeans were a people of southern Mesopotamia, in what is now southern Iraq, known in the ancient world as careful watchers of the sky. Their base-60 counting still shapes how we keep time, with 60 minutes in an hour and 360 degrees in a circle. Cheiro drew on that reputation when he named his letter values Chaldean. The history is real. The claim Naksham will not make is that reading single digits for personality is itself ancient. That part is modern.
How the Chaldean Map Differs from the Pythagorean One
The two best-known letter maps in numerology are the Chaldean and the Pythagorean. They differ in how each letter earns its number. Knowing the difference explains why Naksham builds its name readings on the Chaldean map.[3]
Sound vibration, not alphabet order
The Pythagorean map runs straight down the alphabet. A is 1, B is 2, C is 3, on to I is 9, then it starts over at J is 1. It is tidy and easy to learn. The Chaldean map works differently. Each letter takes a number from the sound it carries. The letter “S” sits at 3 in Chaldean but at 1 in Pythagorean. The letter “F” sits at 8 in Chaldean but at 6 in Pythagorean. The Chaldean groups follow how letters sound, not where they fall in the alphabet.
The name you go by
Pythagorean readings usually start from the full name on your birth records. Chaldean readings lean on the name people actually call you, because the sound in daily use is the one alive around you now. Naksham follows the Chaldean lead here. You enter the name you go by, and the tool reads that.
Compound numbers add a second layer
The Pythagorean method reduces almost every total to one digit. The Chaldean method first reads the compound, or two-digit, number, then reduces it. A name that totals 23 is not only a 5. The compound 23 carries its own meaning, called the “Royal Star of the Lion” in the Chaldean record, and it colours how that 5 shows up.[1] This two-layer reading is one reason Naksham kept the Chaldean map.
The Sacred Number 9, and Why No Letter Maps to It
The clearest mark of the Chaldean map is how it treats the number 9. In the Pythagorean map, 9 is handed to letters like I and R the same as any other digit. In the Chaldean map, 9 is held back as sacred and is never given to a single letter.[1]
The Chaldean record reads 9 as the number of completion. The reasons are part math and part meaning:
- Any number times 9 gives a result whose digits add back to 9. For example, 9 x 7 = 63, and 6 + 3 = 9.
- Add 9 to any number and the digits of the answer add back to the first number. For example, 5 + 9 = 14, and 1 + 4 = 5.
- The number 9 takes in every other number while leaving it unchanged, a quality the Chaldean record tied to the divine.
Because 9 stands for the highest single-digit force and for selfless care for others, the Chaldean map keeps it out of plain letter sounds. It shows up only when a name adds up to 9 or a multiple of 9 on its own, and when it does, the reading carries real weight.
In the Indian number-and-planet map, 9 belongs to Mangal (Mars), the planet of courage and decisive action. Both the Chaldean and the Indian readings treat 9 as the number that closes one cycle and opens the next.[4]
The Chaldean Letter-Number Chart Naksham Uses
The table below shows the Chaldean value for each letter of the English alphabet. These are the exact values Naksham reads for your Naamank (name number), Soul Urge, and Personality numbers. The values run from 1 to 8 only. The number 9 is left out of letter assignments, for the reason above.
| Number | Letters Assigned |
|---|---|
| 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 |
How to read this chart: Find each letter of the name, note its Chaldean value, then add the values. If the total has two digits, read the compound number first, then reduce it to a single digit for the root vibration.
Take the name “NAKSHAM.” The Chaldean values are N=5, A=1, K=2, S=3, H=5, A=1, M=4. The total is 21. The compound 21 is called the “Crown of the Magi,” one of the most fortunate compound numbers, tied to honour and success after early effort. The root is 2 + 1 = 3, the number of warmth and self-expression, linked to Guru (Jupiter) in the Indian map.[1]
Why Naksham Reads Names with the Chaldean Map
Practitioners have weighed the Chaldean and Pythagorean maps for a long time. A few points settled the choice for Naksham:[3]
Sound-based values match how names are spoken. The Chaldean map groups letters by the sound they make. “C” as in “cat” and “K” make a close sound, and both sit at 3 in Chaldean. In the Pythagorean map, C is 3 and K is 2, a split with no basis in sound. If numerology works through vibration, the map that follows sound is the better fit.
Compound numbers add depth. The Pythagorean map gives one digit for most names. The Chaldean map gives two readings at once. The compound number shows the outer pattern, and the root digit shows the core. A name that totals 14, which reduces to 5, reads very differently from a name that totals 23, which also reduces to 5. The Chaldean map keeps them apart.
Cheiro's own practice. Count Louis Hamon, known as Cheiro, was the best-known numerologist of his day, read by figures like Mark Twain and Thomas Edison. After years of work with both maps, he backed the Chaldean values as the more dependable way to read character. Naksham follows that lead.[1]
Chaldean Values and Indian Ank Jyotish, One Shared Map
India's own number tradition, Ank Jyotish, shares its core with the Chaldean reading. Both give each single digit a ruling planet.[2]
In Ank Jyotish, the map runs 1 = Surya (Sun), 2 = Chandra (Moon), 3 = Guru (Jupiter), 4 = Rahu (North Node), 5 = Budha (Mercury), 6 = Shukra (Venus), 7 = Ketu (South Node), 8 = Shani (Saturn), and 9 = Mangal (Mars). The Chaldean reading shares the opening planets, with 1 as the Sun, 2 as the Moon, and 3 as Jupiter.[4]
It helps to be clear about the layers again. This single-digit number-and-planet map is a modern reading. Cheiro set down a Western form in 1926, and Indian authors such as Harish Johari in 1990 and Pt. Gopesh Kumar Ojha gave it the navagraha form used here.[4] Classical Sanskrit astronomy, in texts like the Vedanga Jyotisha, carries no digit numerology.[5] What does come from the classical texts is the planet layer it leans on. The gem, colour, metal, and mantra tied to each planet are drawn from classical sources. Naksham keeps the two layers labelled so the reading stays honest.
One Vedic Method, Chaldean Values Inside It
Naksham runs a single numerology method, Vedic Ank Jyotish. There is no Chaldean-versus-Pythagorean switch to set. For any name in English letters, the tool reads the Chaldean values on this page for your Naamank (name number), Soul Urge, and Personality. For your date of birth, it reads your Bhagyank, the Destiny Number also known as the life path number.
Every name reading shows both the compound number and the root digit, the two-layer depth the Chaldean map is known for. The number meanings are a modern reading, while the planet and remedy notes are drawn from classical texts, and each is labelled for what it is.
Whether you are checking your own name, a business name, or a lucky number, you are using the one Vedic Ank Jyotish method, with the Chaldean values doing the letter math underneath. Start with the tools below.
