Alright, let me walk you through how I put together my own Chaldean numerology calculator thing. It wasn’t super complicated, but it took some figuring out, step by step.
Getting Started – The Idea
I’d been messing around with numerology for a while, you know, just for fun. Mostly the Pythagorean system ’cause it’s everywhere. But then I stumbled onto the Chaldean system, which felt a bit more… ancient? Mysterious? Anyway, I got curious. Trying to do the calculations by hand for every name got old fast, especially the Chaldean way. So, I thought, “Hey, I can probably make a simple tool for this.” That’s how it started.
Step 1: Digging Up the Rules
First thing, I had to really nail down the Chaldean letter values. It’s different from the other systems. Like, A is 1, B is 2, sure, but then G is 3, D is 4… and it only goes up to 8. No number 9 assigned to letters. I spent a good chunk of time just finding reliable charts and cross-referencing them. Found a few variations online, so I had to pick one source I trusted and stick with it. I wrote down the mapping:

- 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
Important bit: Chaldean uses the name you’re most commonly known by, not necessarily your full birth certificate name. That was a key detail I made sure to remember.
Step 2: Figuring Out the Math Part
Okay, got the letters and numbers. Next was how to actually calculate. You take the name, convert each letter to its number using that chart I made, and then you add ’em all up. Pretty simple so far.
But the Chaldean system puts a lot of weight on the compound numbers (the double-digit totals) before you reduce them to a single digit. Like, 15 has its own meaning, different from just 6 (1+5). So, the calculator needed to show both: the total sum (compound number) and the final single digit (the ‘root’ number). Reducing is easy, just add the digits of the compound number together until you get a single digit (like 15 -> 1+5 = 6, or 28 -> 2+8 = 10 -> 1+0 = 1).
Step 3: Building the Thing
I didn’t need anything fancy. I just used some basic scripting, something simple I could run on my computer. The core task was: take a name as input, go through each letter, look up its value from my list, add it to a running total.
I decided to make it ignore spaces and handle both uppercase and lowercase letters. That took a little extra logic – basically telling it to treat ‘a’ the same as ‘A’. Had a small hiccup where it choked on punctuation, so I added a step to just strip out anything that wasn’t a letter before doing the calculation.

Once I had the total sum, I added the part to calculate the single-digit root. Displaying both was key.
Step 4: Testing and Tweaking
With the basic calculator built, I started testing. I grabbed names of people I knew, famous names, names from examples I found during my research. I did the calculations by hand alongside the calculator to make sure it matched. Found a couple of small bugs this way, mostly typos in my initial letter mapping, which I fixed quickly.
It felt pretty good seeing it spit out the right compound and single-digit numbers instantly. Much faster than doing it manually!
Step 5: Adding the ‘Numerologist’ Touch (Optional-ish)
Just having the numbers is cool, but the ‘numerologist’ part means knowing what they mean. So, the final step for me was adding brief interpretations for the single-digit numbers (1 through 9) and maybe some key compound numbers that pop up often. I grabbed these interpretations from the same sources I used for the letter values. This turned it from just a calculator into something that gives a little insight, which was the whole point.
And that was pretty much it. Started with curiosity, did the research, figured out the logic, built a simple tool, tested it, and added some basic meanings. Now I have my own little Chaldean calculator ready whenever I want to check a name. It was a fun little project, honestly.
