What is the Synastry Love Calculator?

Synastry places two birth charts together and looks at the angles between one person’s planets and the other person’s planets. It can offer language for talking about differences and shared strengths.

A compatibility score is only a summary of this tool’s chosen rules. It cannot measure consent, safety, care, honesty or the choices people make.

How it works

The tool compares major aspects between both charts, then groups them into reflection categories. Birth time improves house context but is not required for basic planetary aspects.

How it connects to your star sign

This tool uses the tropical zodiac and an analytical ephemeris unless the method says otherwise. Astrology is a symbolic tradition, not a scientific test.

Common questions

Can this tool predict what will happen?

No. It calculates astronomical positions and presents traditional symbolism. It cannot guarantee events or replace practical judgment.
