In Chaldean numerology every letter carries a value from 1 to 8. The total of your name reduces to a single number with a ruling planet, and that planet should be friendly to the planets of your Mulank (birth day) and Bhagyank (full birth date).
When is correction worth it?
If your name number is friendly to both, no change is needed. If it clashes with one of them, a small spelling change — adding or doubling a letter — can bring it into harmony without changing how the name sounds.
Using the new spelling
Use the corrected spelling consistently: signature, email, social profiles and business cards. Official documents can be updated later if you wish.
