The Birthday Number, also called the Day of the Month or Personality Number is strongly associated with the Life Path number and can be invaluable to know.

Revealing your innate personality traits, characteristics and born behaviors, knowing your Birthday Number can be instrumental in both mitigating any negative or over-exaggerated aspects of your Life Path number, or enhancing them.

Here’s an example: Let’s say you are a 1 Life Path who also has a Birthday Number 1.  This multiplicity of 1s may be a little too much for others to take at times, as this over-enhanced “I am” energy is likely to emerge in arrogant or self-centred behaviours. However, if you are a 1 Life Path with a Birthday Number of 9, your potential arrogance may somewhat be tempered by the humble, self-sacrificing nature of the number 9.


Of course, virtually everybody knows their Birthday Number (even if they don’t already know its numerology) and very little summing and reducing is required. It is the calendar day you were born on, and when this is a double digit, it contains the qualities of the sum and of both individual digits.

Read on for your quick reference guide to the dominant personality traits revealed by your Birthday Number!
