Numerology is the old practice of giving meaning to numbers. It is not a science, but many people enjoy it as a fun way to think about their strengths and habits. One of the simplest numbers to work out is your birth day number – based only on the day of the month you were born.
How to find your birth day number
Take the day of your birth (1 to 31). If it has two digits, add them together until you get a single digit.
- Born on the 7th? Your number is 7.
- Born on the 14th? 1 + 4 = 5.
- Born on the 29th? 2 + 9 = 11, and 1 + 1 = 2.
Some numerologists keep 11 and 22 as “master numbers” rather than reducing them. If you were born on the 11th or 22nd, you can read both the master number and its reduced form (2 or 4).
Why the birth day?
Numerologists usually work with several numbers. The life path number uses your full birth date and is said to describe your overall journey. The birth day number is smaller and more specific – it is often described as a natural gift you bring to everything you do.
