What is a Synastry Calculator?

Synastry is the branch of astrology that compares two people's birth charts to understand their relationship compatibility. A Synastry Calculator analyzes the 'aspects' (angles) between planets in both charts (e.g., your Moon to their Venus) to reveal areas of emotional connection, sexual chemistry, intellectual harmony, and potential conflict.

Planetary Connections

In synastry, we look for 'conjunctions' and 'trines' which indicate easy flow, and 'squares' or 'oppositions' which indicate growth-oriented friction. Venus-Mars aspects often show physical attraction, while Moon-Sun aspects show deep emotional understanding.
