In Chaldean numerology, different versions of your name reveal different layers of who you are. It's worth calculating all three below to see the fuller picture.
The exact name on your birth certificate. This reveals your destiny, your natural talents, and your life purpose — the core energies you were born with.
The name you actually go by day to day — first name and current last name, or a nickname. This shows how the world sees you right now, and the energy you project to coworkers, friends, and family.
Just your first name on its own. This reveals your innermost desires, your private habits, and who you are when you're completely alone.
Fill in as many as you'd like — you don't need all three.
Once you have your number, look it up here to understand what it says about you.
