Basic zodiac compatibility tells you whether two signs tend to get along. Synastry tells you the whole story.
A synastry chart overlays two people’s birth charts to reveal exactly how their planets interact — where one person’s Mars falls in the other’s chart, how their Venuses speak to each other, and what the karmic undertones of the relationship might be. It’s the tool astrologers use to go beyond ‘are you compatible?’ and into ‘how do you actually experience each other?’
Enter both birth details below for a free synastry reading. For best results, use exact birth times for both people.
