Finding your birth day number is the easiest calculation in numerology. You only need one piece of information, the day of the month you were born. Nothing else. No year, no month. Just the day.
Look at the day you were born, is it a single digit? Then that is your birth day number, born on the 5th? Your number is 5, born on the 9th? Your number is 9, simple and direct.
If your birth day is a double digit from 10 to 31, you need to reduce it. Add the two digits together. Keep adding until you get a single digit. The only exceptions are 11 and 22, which are master numbers.
It helps to walk through examples, born on the 14th. Add 1 plus 4. That equals 5, your birth day number is 5. Born on the 28th, add 2 plus 8. That equals 10, then add 1 plus 0. That equals 1. Your birth day number is 1.
Born on the 30th, add 3 plus 0. That equals 3. Your birth day number is 3, see how easy it’s. No complex math required. Anyone can do this in seconds.
The master number exceptions matter. If you were born on the 11th, don’t reduce. Your birth day number is 11. If you were born on the 22nd, do not reduce. Your birth day number is 22. These are powerful numbers.
Born on the 29th, this one is tricky. Two plus nine equals 11. You don’t reduce 11 further, so birth day 29 gives you master number 11. The reduction stops at 11, 22, or any single digit.
