Sun numbers in numerology

The Sun Number in numerology is calculated by adding your birth month and birth day, then reducing the total to a single digit from 1 to 9. It is also called the Attitude Number in some numerology systems. The Sun Number numerology idea came from the famous numerologist Hans Decoz. This system helps to understand personality traits, characteristics, first impressions, and more.

How to Calculate Your Sun Number

Calculating your Sun Number is very simple; you just need your birth month and birth day. Add the numerical value of your birth month to the day you were born. Then add the digits of the total until you get a single digit from 1 to 9.

Formula:

Birth month + birth day = total, then reduce the total to a single digit by adding its digits until one digit is left.  

Examples of Sun Number Calculation

Example 1: Born on May 15

• Birth month: May = 5
• Birth day: 15
• Calculation: 5 + 15 = 20
• Reduce: 2 + 0 = 2

Sun Number: 2

Example 2: Born on November 23

• Birth month: November = 11
• Birth day: 23
• Calculation: 11 + 23 = 34
• Reduce: 3 + 4 = 7

Sun Number: 7

Example 3: Born on September 29

• Birth month: September = 9
• Birth day: 29
• Calculation: 9 + 29 = 38
• Reduce: 3 + 8 = 11, then 1 + 1 = 2

Sun Number: 2

Note: In this sun number numerology calculator method, master numbers such as 11 and 22 are also reduced to a single digit. This means a total of 11 becomes 2, while 22 becomes 4. Some numerology systems keep 11 and 22 unreduced, so it is important to follow one method consistently. 

The table below shows the value of each month:

Month	Month Number	Value Used
January	1	1
February	2	2
March	3	3
April	4	4
May	5	5
June	6	6
July	7	7
August	8	8
September	9	9
October	10	1 (1+0)
November	11	2 (1+1)
December	12	3 (1+2)
