Click any number for the full pairing. Scores come from the aspect between the two signs, not from a table of opinions.

How the angle decides

  • 0° conjunction — the same sign. Recognition, and a doubled blind spot.
  • 30° semi-sextile — neighbours. Little in common; mild mutual bafflement.
  • 60° sextile — complementary elements. Easy and cooperative.
  • 90° square — same modality, clashing elements. Friction that produces movement.
  • 120° trine — same element. The smoothest pairing there is.
  • 150° quincunx — nothing shared at all. Requires deliberate translation.
  • 180° opposition — across the wheel. Each holds what the other lacks.

Because signs are evenly spaced, these angles are fixed. Aries and Leo are always 120 degrees apart, so they always form a trine. Nothing here is a matter of taste.

What a score is worth

Nothing predictive. No study has found an association between birth dates and relationship outcomes, and the strongest pairing on this grid will not save a relationship that two people are not working at.

What the aspects describe reasonably well is the kind of difficulty a pairing tends to produce. A square is not worse than a trine — it is louder, and it moves. Plenty of people find a trine boring.
