Relationship Score

Life path: sum the birth date digits (YYYYMMDD), then reduce to a single digit. Master numbers 11, 22, 33 are preserved (not reduced).

Birth day: use the day of month, then reduce (11 and 22 are preserved).

Expression: reduce each name part to a single digit (or master number), then sum those parts and reduce again. Letter mapping: A-I to 1-9, J-R to 1-9, S-Z to 1-8. Special mapping: Æ = 9, Ø = 1, Å = 2.

Scoring: compatibility labels from the dataset map to scores (easy=95, compatible=80, neutral=65, challenged=50). Master numbers are reduced to 2/4/6 for compatibility lookup. Final score is the average of available components.

Expression totals are higher-octave values for the expression number.

Current pair: life path

Data notes: Anne Jonsdatter Sundal: life path uses year only (missing month/day). Anne Jonsdatter Sundal: missing birth day for birth day compatibility. Knut Gregoriusson Årøy: life path uses year only (missing month/day). Knut Gregoriusson Årøy: missing birth day for birth day compatibility.

Signs use a 12-year cycle with a Chinese New Year cutoff when month/day are known. Elements use the year last digit (0-1 Metal, 2-3 Water, 4-5 Wood, 6-7 Fire, 8-9 Earth). If month/day are missing, the Gregorian year is used.
