Compare two birth charts: affinities, communication and points of friction between their planets.

How the reading works

Tropical geocentric positions and five major aspects. Contacts involve at least one personal planet or ascendant; no compatibility percentage is assigned. When the birth time is unknown, Moon and ascendant aspects and contacts that may change during the day are omitted. Houses are not compared.

Symbolic meaning; the calculation does not establish personal traits or predict events.

What this tool helps you explore

Synastry compares two birth charts to explore affinity, communication and friction. It relates one person's planets to the other's instead of reducing the relationship to two Sun signs.

How to use it

Enter both people's birth details and select their cities. Use known local birth times or mark the time as unknown. Calculate and explore the highlighted contacts; real names are not required.

Reading your result

Read supportive contacts alongside tense ones: both describe themes in the interaction. There is no overall compatibility score. Missing times cause some points to be omitted; this reflects limited data, not a lack of connection between the people.
