Synastry
Synastry compares two charts through positions and angular relationships. It differs from a table comparing only two Sun signs.
How it is defined
Available data constrain its scope. A symbolic score is not a probability of success or a way to know another person’s private feelings.
How to read it
A useful reading explains its rule before proposing questions. Keep the compared data distinct from the meaning a particular school assigns to it.
A concrete example
Explore the questions raised by an affinity and the agreements required by a difference. The sign-compatibility application does not calculate full synastry.

Before extending a reading, identify the data the technique requires and what the application actually provides. Keep the rule with your notes so comparisons use consistent criteria.
