Name Numerology FAQs
What name should I enter?
Enter the exact Roman or Latin spelling you want analysed.
Does spelling change a name number?
Yes. The submitted supported letters determine the totals, so another spelling can produce another value.
What is the difference between Chaldean and Pythagorean numerology?
They assign different values to letters. DevDarsha returns and displays each system separately.
What is an Expression Number?
It is calculated from all supported letters in the submitted name.
How is the Soul Urge Number calculated?
It is calculated from vowels in the normalized name.
How is the Personality Number calculated?
It is calculated from consonants in the normalized name.
Does DevDarsha store my submitted name?
No. The name is transient input and is not placed in URLs, analytics, browser storage or application logs.
Why do the two systems give different results?
Chaldean and Pythagorean systems use different letter mappings. The results are intentionally kept separate.
What happens when the result is 11, 22 or 33?
A Master Number badge appears only when the engine explicitly marks the value as preserved.
