What synastry shows

The actual contacts between two charts

Synastry looks at the actual contacts between your charts: which planets meet, at what angle, with what orb. Resonance where it exists, friction where it exists, and the aspect behind every sentence.

Each axis shows resonance, friction, or a mix, always with the aspects it rests on.

FAQ

Questions people actually ask

What if one of us doesn’t know their birth time?
The planet-to-planet aspects still compute. That’s most of the read. What we skip is the house overlays and any contact to the Ascendant/Midheaven, because those depend on the exact time. We tell you what’s missing instead of assuming noon.
Do I need the other person’s permission?
Data you enter for someone else is marked as yours and deletable in one click. The cleaner path is an invite link: they fill in their own details, see their own side of the read, and can decline. Nothing is sent on your behalf.
Is this romantic-only?
No. Synastry compares any two charts: friends, family, colleagues. Pick the relationship type and the read is framed accordingly.
