The six core numbers, worked through
An example chart for Emily Rose Carter, born 15 July 1990, calculated by the same code as the calculator above.
The Pythagorean letter table
Letters run 1 to 9 and start again — A is 1, I is 9, J is 1 again. Master numbers 11, 22 and 33 are kept whole when a total reaches them; 13, 14, 16 and 19 on the way down are read as karmic debt numbers.
| 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 |
|---|---|---|---|---|---|---|---|---|
| A | B | C | D | E | F | G | H | I |
| J | K | L | M | N | O | P | Q | R |
| S | T | U | V | W | X | Y | Z |
The Chaldean system, which assigns by sound and never uses 9 →
Which name to use
The traditional choice for the Expression number is the full name on your birth certificate — middle names included, however much you dislike them. A married or chosen name is read as a second influence layered over the first, not a replacement.
This matters more than it sounds: the name-derived numbers change if the name changes, while the Life Path never does. That asymmetry is why practitioners treat the Life Path as the anchor of a chart.
Nothing is stored
The calculation runs on the server and the result is rendered straight into this page. Your name and date are not saved, logged against you, or sent anywhere.
