Choose the right numerology tool
This page is a hub for the site's distinct numerology and symbolic-number tools. The quick calculator above returns only the core arithmetic values. Use the linked combined profile when you also want the site's derived lucky-number list, or the angel-number page when you already have a repeating digit sequence to look up.
Life path and birth day
Enter a complete date above. The life path reduces month + day + four-digit year; the birth day reduces the day of the month.
Destiny number
Uses all mapped characters in the entered name and reduces their sum.
Soul urge number
Uses the mapped values for the Latin vowels A, E, I, O, and U.
Personality number
Uses mapped non-vowel characters that receive a nonzero value.
Reduction rule
A value is reduced by repeatedly adding its decimal digits until it is a single digit. The traditional master-number values 11, 22, and 33 are retained rather than reduced again. A zero sum remains zero. These rules are conventions used by this site, not scientific measurement.
Name mapping
| Value | Letters |
|---|---|
| 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 |
Spaces add zero. For compatibility with the homepage, a non-Latin, non-whitespace character uses (first UTF-16 code unit % 9) + 1. This fallback is not a validated transliteration and should not be treated as culturally authoritative.
Worked examples
Ada Lovelace maps to a full-name sum of 36, so the destiny number is 3 + 6 = 9. Its vowels total 19, producing soul urge 1, while the remaining mapped characters total 17, producing personality 8.
For December 10, 1815, the life path input is 12 + 10 + 1815 = 1837. Digit reduction produces 1 + 8 + 3 + 7 = 19, then 10, then life path 1. The day 10 reduces to birth day 1.
