4.1 : How to Calculate Your Birth Number
In Chaldean Numerology, your Birth Number is the most straightforward calculation — it comes directly from the day of the month you were born. Unlike the Life Path Number (which uses your full birth date), the Birth Number is simply the date (1–31). It never changes and reflects your core nature — your personality’s vibration, natural tendencies, and how you approach life.
Step 1: Take Your Birth Day
Rule Your Birth Number is the calendar day you were born.
If you were born on the 4th, your Birth Number is 4.
If you were born on the 17th, your Birth Number is 17.
Step 2: Understand Root & Compound Numbers
Root Number → Add the digits of the day until you reach 1–9.
Compound Number → The original two-digit (or three-digit) day also has its own unique meaning.
This is where Chaldean Numerology differs from most Western systems: you read both the root and the compound together.

Step 3: Apply the Chaldean Lens
Pay special attention to compounds: 10, 11, 12, 13, 14, 16, 18, 23, 26, 29, 30, 31 — these carry strong meanings that should not be ignored.
- The root gives your basic personality traits.
- The compound reveals hidden karmic lessons, destiny patterns, or protection.
