Astrology Synastry Chart

Choose a relationship and roles → Compare charts → Read each direction

Without a birth time and place there are no houses, and house overlay is the richest layer in synastry. The Moon also moves about 13° a day, so a noon estimate can be off by more than the synastry orb — with no time, treat anything involving the Moon as directional only.
