Synastry
Synastry lays one birth chart over another to show how two people's planets talk to each other: where the relationship flows, where it sparks and where it needs care.
Compare our chartsFree with an account: both Big Threes and the main aspects between you. Premium reads the whole relationship.
Sign compatibility compares two Sun signs, so it says the same thing about every Leo and Libra. Synastry uses both full birth charts: the Sun, Moon, Rising sign and every planet, down to the degree. That is why two couples with the same signs can have very different relationships.

Two planets in the same place. The strongest bond: the two energies blend, for better or worse.
An easy flow. Things you understand about each other without having to explain.
A friendly opening. Support that grows when you both make a little effort.
Friction that asks for growth. Often where the spark and the arguments come from.
A pull between opposites. Attraction and balance, as long as neither of you tugs too hard.
Both birth dates. Birth times and cities make it more accurate, because they set the Moon's exact degree and each person's Rising sign and houses.
Yes. The Sun and most planets barely move in a day, so their aspects hold. The Moon and Rising sign are the parts that need a time.
Comparing two charts is free with an account: you see both Big Threes and the main aspects between you. Premium adds a written reading of the relationship.
