How to calculate your Birthday number
Add the digits of your birth day until one digit remains, stopping if you reach 11 or 22. You do not need your birth month, year, time or place.
For example, the 14th gives 1 + 4 = 5. The 29th gives 2 + 9 = 11, which this calculator keeps. The 22nd stays 22. A day between 1 and 31 cannot produce 33 under this rule.

Questions about Birthday numbers
Is my Birthday number the same as my Life Path?
No. Birthday uses the day alone, while Life Path uses month, day and year. A person born on the 14th has Birthday number 5 under this method, regardless of the rest of their date.
Why does another site describe all 31 birth days separately?
Some numerology readings retain the original birth day, such as 14, as well as its reduced value, 5. Our calculator displays the reduced result while the table above lets you retain the original day as context.
Why is the 29th an 11 rather than a 2?
This calculator stops reduction at 11 and 22. Other conventions reduce every result to one digit. You can read 11 alongside its underlying 2 and 22 alongside its underlying 4, but we display the master number.
To add your birth month to a date-based reading without using the year, try the Sun or Attitude number calculator.
