What is a natal compatibility (synastry) reading?

Synastry compares two birth charts — placing one person's planets against the other's — to read the connection: attraction, communication, emotional needs, conflict, and staying power. It shows how two distinct people actually affect each other.

Anyone weighing a relationship that matters — partners, dating, close friends, family, or collaborators. It's especially useful when a connection feels intense and you want to understand why.

What information do I need?

Both people's birth date, birth time, and birthplace. Birth time matters a lot in synastry — it sets the houses, Moon, and rising signs that drive the chemistry.

What will it tell me about us?

Where you naturally click, where you grate, what each person brings, and the themes the relationship keeps circling back to — a grounded read of the dynamic, not a yes/no verdict.

It's descriptive, not fated. It names real tendencies in how the two of you work, so you can lean into the strengths and handle the frictions with your eyes open.

Your natal chart is a snapshot of the sky at the exact moment and location you were born. Every planet was somewhere in the zodiac; the horizon was cutting through a specific sign.

Astrologers read that configuration as a map of your psychology — the drives you carry, the arenas where they play out, and the conversations between them. The astronomy is precise and verifiable; the interpretation is where meaning lives.

Each sign is a 30° arc of the sky — the constellations the planets appear to move through.
