What you’re seeing in your free synastry chart

Your synastry chart has 3 layers:

the two of you

both birth charts on one wheel

the aspects

how your planets act on each other

the composite

the chart for the relationship itself

Each layer shows part of the relationship. Together they tell the story.

What Is a Synastry Chart?

A synastry chart lays one birth chart over another and shows exactly where they meet.

Your planets sit on the main ring with your houses around the wheel. The other person’s planets sit on a ring inside yours, so you can see at a glance which of your houses their Sun, Moon, Venus and Mars fall into. Today’s transits sit just outside the zodiac.

The lines in the center are the tightest aspects between the two of you, each one a place where your energy and theirs act on each other, sometimes easily, sometimes with the kind of friction that keeps you both adjusting.

See It From Both Sides

The same relationship can feel very different depending on whose chart you are standing in.

One tap switches between your houses and theirs. In your houses, you see where they land in your life. In theirs, you see where you land in their life, which is often the part of the chart that explains why the two of you remember the same moment so differently.

The Composite Chart

The composite chart takes the halfway point between each of your planets and builds one chart from them.

It describes the relationship as its own presence, the thing the two of you make together. Today’s transits show on the composite as well, so you can see when the sky is touching the relationship itself and not only one of you.

Why Both Birth Times Matter

Birth times set the houses and the Ascendant, which is what lets the chart show where you land in each other’s lives.

If one of you is missing a birth time, tick the box on the form. The planet to planet aspects still work, that person’s houses and angles drop out, and their Moon is marked approximate, since the Moon moves about 13 degrees in a day.

Frequently Asked Questions About Synastry Charts

What is a synastry chart?

A synastry chart compares 2 birth charts by laying one over the other. It shows the aspects between the 2 people’s planets, where each person’s planets land in the other’s houses, and how the 2 charts fit together as a relationship.

Is this synastry chart really free?

Yes. The chart, the closest aspects between you, the house overlays for the Sun, Moon, Venus and Mars, the composite chart and today’s transits are free. Two Charts, One Story, the full written synastry reading, is coming soon.

What do I need to make a synastry chart?

Both birth dates, both birth times and both birth places, plus your email address, since your private chart link is sent there.

Can I make a synastry chart without a birth time?

Yes. Tick the box for an unknown birth time. The planet to planet aspects still work, the houses and angles for that person drop out, and the Moon is marked approximate.

What is the difference between synastry and a composite chart?

Synastry keeps the 2 charts separate and shows how they act on each other. The composite blends them into one chart built from the midpoints between your planets, and it describes the relationship itself.

Can I compare my chart with my child, my parent or a business partner?

Yes. Synastry works for any 2 people. The same aspect can read very differently between partners, between a parent and child, or between 2 people who work together, which is what Two Charts, One Story will read for you.
