How is it calculated?

Each letter maps to a number from 1 to 9 according to the Pythagorean table (A=1, B=2... I=9, J=1, K=2...). All values are summed and the total is reduced to a single digit or master number.

Write your full birth name
Assign the Pythagorean value to each letter (A=1, B=2... I=9, J=1...)
Sum all numerical values
Reduce to a single digit (preserving masters 11, 22, 33)

The correspondence between letters and numbers has roots in Greek isopsephy and Hebrew gematria, systems that Pythagoras integrated into his mathematical philosophy.
