The charts of the people around you, and what they share with yours.

Name

For you alone, and only in this browser. The name is not sent to the server and is not part of the chart.

Date of birth Time of birth

Unknown? Leave it empty. The signs still hold; the houses do not, and house overlays fall away.

Place of birth

Start typing and pick a place from the list.

House system

For a comparison it helps to pick the same system as for your own chart.

Pick a place from the list first.

You are comparing with

No one yet. Add someone alongside; after that Synastry, Composite and House overlays fill up.

Three ways to compare two charts

Synastry lays out the angles between both charts, Composite makes a third from the midpoints, and House overlays shows in whose houses the other's planets fall. They answer different questions.

What a comparison does not do

No score comes out and no verdict. What lies there are angles between positions; what they mean is tradition, and that difference stays as visible here as anywhere else.

Without a birth time

If either side lacks the hour, the houses on that side are unreliable and the overlay falls away. Aspects between the planets stay usable.
