Frequently Asked Questions
What is a Synastry Chart?
A Synastry chart overlays two natal charts to see how the planets of one person interact with the planets of the other. It's the standard tool for assessing relationship compatibility.
Is birth time necessary?
For accurate House overlays and Moon position, birth time is crucial. Without it, we can still analyze planetary aspects but with less precision.
What is the most important aspect for love?
Sun-Moon conjunctions and Venus-Mars aspects are often considered the strongest indicators of attraction and emotional bonding.
Can a 'bad' chart work?
Yes! 'Hard' aspects (squares, oppositions) create tension but also growth. A relationship with only 'easy' aspects might lack the energy to evolve.
