Relationship Score

Compatibility note (4 and 5): Challenge. The 4 and the 5 have different temperaments and different ways of communicating. The 4 is very direct to the point, while the 5 will be more diplomatic and indirect. 4s don't like change, and 5s have to have it. To find success, this couple will need to respect the difference and pay attention to what is said and what is inferred.

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 4 / 5 ; expression 7 / 9 ; expression totals 7 / 18 ; birth day 4 / 10 .

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.
