Numerology is the study of the symbolism of numbers. It uses numbers as a key to human behaviours. There are nine planets which have greater influence on the human life and each of them has been allotted a particular number.

Name numbers are sum value of a name which vibrates various energy and expressions. Number 1 to 8 are assigned for alphabets in the Chaldean System.
1 is the value of A I J Q and Y
2 is the value of B K and R
3 is the value of C G L and S
4 is the value of D M and T
5 is the value of E H N and X
6 is the value of U V and W
7 is the value of O and Z
8 is the value of F and P
As you may already have noticed no alphabet letter was assigned to the number 9. The reason why the number 9 was omitted under Chaldean Numerology System was because the Chaldean felt the 9 was holy sacred and thus to be held apart from the rest. However should your name or that of someone you know total 9 then the 9 remains.
