Psychomatrix compatibility - two Pythagorean squares
Pythagorean-square compatibility: two psychomatrices side by side. Green is close counts, not a grade of the pair. The link keeps both dates.

Pythagorean compatibility by two birth dates
A free online comparison of two dates. Each date becomes an Alexandrov square, then the page sets the squares side by side. Time, place and name are not in the formula.
The result is the gap on 9 traits and 8 lines, not a love percentage and not a verdict on the relationship.
What the table compares
Character, energy, interest, health, logic, work, luck, duty and memory, plus the eight lines: aim, family, stability, self-regard, money and home, talent, spirit and temperament.
A small gap is not automatically good. Two empty cells are a match in a weakness. Sex is not in the formula: any two birth dates use the same table.
How we score compatibility
We build two Alexandrov squares - the same working numbers, zeros stay out of the cells.
For each line and cell we take the delta (difference). Δ = |count A − count B|
- 0–1close
- 2–3a noticeable difference
- 4+a zone to agree
The core of the pair is character (1) and energy (2); logic (5) sits on four lines at once.
The overall number is mean closeness, not a divorce forecast. A match at zero or at overload is flagged separately.
Common questions about calculating a Pythagorean square
What does the compatibility calculator compare?
Two psychomatrices: 9 traits and 8 lines. We look at the gap of counts, not “you fit / you don’t”.
Does a green badge mean all is well?
No. Green means a small Δ. Short bars on both sides are a match in weakness. Two long bars can be competition, not harmony.
Can it predict a divorce?
No. The square shows starting counts, not behaviour. A red pair can last if they talk; a green pair can split if they treat a match as a given.
Why is the percent different on other sites?
Schools write working numbers differently and fold Δ into a percent differently. Here: Alexandrov, Δ on cells and lines, character and energy a little heavier in the mean.
Method and editorial review
- Calculation method: Alexandrov psychomatrix. W2 and W4 are digit-summed once; zero never enters the cells.
