Compatibility calculators

These tools compare two people. The zodiac and numerology calculators name the relation between two signs or two life path numbers, using the element, modality and number families of the tradition. None of them gives a percentage, because the tradition has no such number.

Synastry lays one birth chart over another and lists every aspect between them, with the orb of each. A composite chart takes the halfway point of each pair of planets and reads the result as a chart of the relationship itself. Both work best with birth times and places for both people, and both show every position used.
