Birth chart compatibility
Enter the birth details of two people to compare their charts. Astrologers call this synastry: they look at the angles between the planets of one chart and the planets of the other.

The closest aspects
- Opposition: Person 1's Saturn and Person 2's Mars, 0°30′ from exact. Astrologers read an opposition as a pull between two sides that need balance.
- Trine: Person 1's Mercury and Person 2's Jupiter, 0°31′ from exact. Astrologers read a trine as an easy flow between the two planets.
- Square: Person 1's Venus and Person 2's Moon, 0°35′ from exact. Astrologers read a square as friction that pushes both of you to change.

Questions about chart compatibility
Synastry is how astrologers compare two birth charts. They put one chart over the other and look at the angles between the planets of one person and the planets of the other.
Start with the closest aspects, because astrologers give a small orb the most weight. Trines and sextiles are read as easy links. Squares and oppositions are read as tension, which can also bring growth. The element balance shows whether the two of you lean the same way or complete each other.
A single number would hide what the charts actually show. Two charts always have some easy aspects and some hard ones, and astrologers read them together. We show the aspects and leave the reading to you.
Tick “I don't know the birth time”. We then set that chart for noon and leave out the rising sign. The Sun and the planets move slowly, so most aspects stay the same. The Moon can be off by a few degrees.
The tropical zodiac, which Western astrology uses. Its first sign, Aries, starts at the March equinox. The signs are not the same as the constellations with the same names.
Yes. Each button opens the poster editor with that birth moment. The last one opens the editor with no date, so you can enter the night you met.
