A numerological number based on the day of birth. It uses less information than the life path number from day, month, and year. Reduction depends on the method.
An example
For someone born on the 14th, simple reduction can give 1 + 4 = 5. That calculation alone does not determine their life path number.

A personal year also uses the birthday but adds the month and selected year. Similar inputs do not make the calculations interchangeable.
Calculation and method
Use the day, month, and full birth year. For April 12, 1990, the digits add up to 1 + 2 + 0 + 4 + 1 + 9 + 9 + 0 = 26. Then 2 + 6 = 8. This example illustrates basic reduction. Master number cases also depend on the stated stopping rule.
