Our date-reduction convention

For date-based calculations on this site, we reduce month, day and year components while preserving 11, 22 and 33 when they occur, then reduce the combined total again. This is one common convention, not the only numerology convention.

Example

For 1990-07-24: month 7 stays 7; day 24 reduces to 6; year 1+9+9+0 = 19, then 10, then 1. Add 7+6+1 = 14, then reduce to 5. Under this convention, the Life Path result is 5.

Name-based numbers

Expression, Soul Urge and Personality calculations require a letter-to-number mapping. Because spelling and name conventions can differ, the launch calculator focuses on date-based numbers where the input is unambiguous.
