Relationship Compatibility Calculator
Analyze the unique dynamics of your relationship. Using professional synastry techniques, we compare planetary positions to reveal strengths and growth areas.
Understanding Synastry
Synastry is the art of relationship astrology. By overlaying two birth charts, we can see how your planets interact with your partner's. It goes beyond simple Sun sign compatibility to look at the Moon (emotions), Mercury (communication), Venus (love), and Mars (passion).
The Big Three in Love
- • Sun: Core ego alignment and life direction.
- • Moon: Emotional safety and domestic habits.
- • Rising: Initial attraction and physical chemistry.
Key Relationship Planets
- • Venus: Affection style, values, and what we find beautiful.
- • Mars: Drive, conflict style, and sexual energy.
- • Saturn: Long-term commitment and durability.
How to Use This Calculator
Enter birth details for both partners as accurately as possible. While birth time is optional, having it allows us to calculate house overlays—seeing which areas of life (career, home, money) your partner impacts the most.
