Frequently asked questions
What is a synastry chart?
Synastry overlays two natal charts and measures aspects between Person A's planets and Person B's planets—highlighting attraction, friction, and growth themes.
Do I need birth times?
You can view planetary cross-aspects without exact times. House and Ascendant-based interpretations require at least one known birth time.
