Synastry

Synastry compares two natal charts to see where one person's planets fall in relation to another's. It is commonly used to explore attraction, communication, emotional fit, and recurring points of friction.

How astrologers use this idea

No single aspect decides whether a relationship works. Consent, communication, compatible expectations, and lived circumstances matter more than any chart pattern.

Important context

The most helpful reading looks for themes: how each person gives and receives care, handles conflict, and makes room for difference.

Use it with your own chart

Astro Codes currently offers individual natal charts and personal readings; it does not yet offer a synastry calculator.
