You can discover your lucky numbers using your birthday to calculate them. The most popular one is the Life Path Number, which is said to outline your mission in life. To get your Life Path number, you must reduce each number from your birthday, birth month, and birth year to a single digit. Then, you need to add each digit together and keep adding until you end up with one single digit unless you end up with a master number 11, 22, or 33.
If you end up with a master number, consider the guidance of a Numerologist since these are considered special numbers. Apart from getting insight on your Life Path number, you can explore your Attitude number which is supposed to reflect your acquired action in life. To get this number, add the day and month of birth and reduce it to a single digit. For example, August 30th would be 8+3=11 and then 1+1 to get the Attitude number 2.
