How it is calculated

The Birthday Number comes from the calendar day you were born. Under our convention, dates above 9 are reduced while preserving 11 and 22 when they arise. For example, the 24th reduces to 2+4 = 6.

How it differs from Life Path

The Birthday Number uses only the day of the month. The Life Path calculation uses the full birth date, so the two numbers serve different interpretive roles.

How to interpret it

Treat the Birthday Number as a narrow symbolic theme—often framed around a natural talent or mode of expression—rather than a complete personality description.
