Synastry & Composite

Two charts compared three ways: synastry, composite and Davison.

What you get

Pick the second person from your saved charts or type their birth details. Synastry lays one chart around the other and scores the contacts; composite and Davison each build one chart for the relationship.

A synastry score from the cross-aspects, with the strongest contacts listed and the method explained
The second person's planets placed in the active chart's houses
