How sign compatibility works
Compatibility between Sun signs starts from their distance on the zodiac wheel. Signs of the same element sit in trine and understand each other easily; signs in sextile share a light, playful complicity; squares create friction that can become growth; opposites attract because each holds what the other lacks.
Sun signs are only the first chapter. A complete synastry compares Moon, Venus, Mars and the ascendant of both people: it is the next tool we are building.
