Zodiac Compatibility as Entertainment
On this page
Zodiac mode in the CalculatorGeek Love Calculator looks up two sun signs in a fixed 12-by-12 entertainment matrix. It does not generate a birth chart, interpret planets or houses, or estimate a probability of relationship success.
The matrix is symmetric and public in the implementation: Aries plus Leo is the same as Leo plus Aries.
What does a zodiac compatibility score mean here?
It means only that a specific pair of sign labels maps to a specific editorial game value. The value is useful for a repeatable zodiac-themed activity; it is not a finding about two people.
The mode asks for signs directly. It does not infer them from birthdays, which are handled by a separate birthday compatibility method, ask for names, or apply a hidden variation that would make the same sign pair change from visit to visit.
How the symmetric matrix works
Each of the 12 signs forms a row and a column. The value at row A, column B equals the value at row B, column A. That produces 78 distinct unordered pairings when same-sign pairs are included.
The CalculatorGeek model returns the table value directly. It does not reduce it, add a name bonus, or use a random number. This is one of the transparent approaches described in how Love Calculator methods work, and every pair is exercised in the browser/server parity suite.
Published reference pairs
| Pair | Game value |
|---|---|
| Aries + Leo | 92% |
| Taurus + Capricorn | 93% |
| Gemini + Aquarius | 94% |
| Cancer + Pisces | 95% |
| Scorpio + Aquarius | 50% |
| Aries + Aries | 77% |
These numbers disclose implementation behavior. They are not empirical estimates or population statistics.
What this mode does not calculate
The mode does not use birth time, birth location, ascendant, moon sign, planetary positions, aspects, houses, synastry, or transits. Calling the output a birth-chart analysis would be inaccurate.
It also does not collect gender or change the score according to which person is entered first. Those inputs are unnecessary for a symmetric table game.
The scientific evidence boundary
A double-blind test published by Shawn Carlson in Nature examined whether natal charts could accurately describe participants' personality traits. CalculatorGeek cites that work to support a clear boundary: the site does not present zodiac output as validated personality measurement or relationship prediction.
The matrix is labeled entertainment beside the result. A high value is not evidence of safety or compatibility, and a low value should not guide a relationship decision. See compatibility scores versus real relationship factors for a practical interpretation boundary.
Privacy and repeatability
Zodiac mode needs only two sign labels. It does not need names or full birth dates, and the same pair always returns the same table value.
Shared result links may contain the chosen mode and numerical output. They do not need personal names or birthdays to reproduce the result card.
Frequently asked questions
Is zodiac compatibility accurate?
It accurately returns the disclosed table value. The table is not a scientifically validated compatibility model.
Does reversing the signs change the score?
No. The matrix is symmetric.
Does the mode calculate my moon or rising sign?
No. It uses only the two sign labels selected.
Why do other sites show a different number?
There is no controlling zodiac-score standard. Sites can use different editorial matrices or random adjustments.
Can I use the result to judge a relationship?
No. The output does not evaluate behavior, consent, respect, safety, or shared goals.
Primary sources
Implementation and content checks were completed on September 17, 2026. Validation covers table symmetry, all sign-pair values, browser/server parity, result labeling, and evidence wording.
The matrix values are published entertainment values. Carlson's double-blind study is cited for the limitation, not as a source for the matrix.
