What Is My Lifetime Lucky Number?

Your lifetime lucky number is calculated from your birth date. Your birth date can't be changed, which means the primary lucky number calculated from it also won't change.

Use the numerology lucky numbers tool. Provide your name and birth date. Then select the "My most important lucky number" from the list (because the most important is also the lifetime lucky number).

When you click the button, the calculator will provide the lifetime/most important lucky number for you. (For the birth date you provided with your question, your lifetime lucky number is the number 3. Verify it with the lucky numbers tool).

I'm uncertain what your question is about name changes. You may find your answers at the pages linked from the name changes index page.
