Birthday Number Calculator

Enter the day of the month you were born to find your numerology birthday number. The day is reduced to a single digit by adding its digits, and the master numbers 11 and 22 are kept unreduced.

Only the day of the month is used, not the month or year. For example, the 29th gives 2 + 9 = 11, a master number that is kept.

How this works. Your birthday number is computed, never random. The day you were born is reduced to a single digit by adding its digits together (repeating until one digit remains), except that the master numbers 11 and 22 are preserved instead of being reduced further. The master number 33 cannot come from a single day, so it never appears here. Everything runs only in your browser: the day you enter is never sent anywhere.

For entertainment and reflection. Numerology is a symbolic tradition, not a science. The number and its keywords are offered for reflection only, and are not medical, psychological, legal or financial advice.
