What synastry is

Synastry is the overlay of two birth charts. An astrologer looks at the angles the planets of one person form with the planets of the other. That is how you can see why some people feel easy from the first minute, while with others you have to choose your words.

A simple comparison of zodiac signs only counts the Sun. Synastry also reads the Moon (emotions), Venus (love), Mars (passion), Mercury (communication) and Saturn (reliability), which makes it more accurate and detailed.

Five areas of a relationship

Emotional closeness — the Moon's links: how calm and warm you feel together.
Passion and attraction — Venus and Mars: spark, desire, chemistry.
Communication and understanding — Mercury: how easily you talk and agree.
Values and goals — the Sun and Jupiter: whether you look in the same direction.
Reliability — Saturn: whether the bond can outlast time and hardship.

Besides the scores, you will see the specific links between your planets with an interpretation: what joins you and where attention is needed. You also get the couple's chart by the Destiny Matrix method.

Compatibility questions

How is compatibility calculated?

We build the birth charts of both people and compare the positions of their planets, which is called synastry. Harmonious angles between planets raise the score, tense ones lower it. Five areas are scored separately: emotions, passion, communication, values and reliability.

Is it enough to know only the zodiac signs?

The Sun sign gives a general idea, but it is just one of ten planets. Two people with "incompatible" signs can have a wonderful match between their Moons and Venuses. That is why a calculation from full birth dates is more accurate.

Do I need my partner's birth time?

It helps, but it is not required. Without the time the Moon's position is approximate, so the emotional closeness score may differ slightly. The other planets barely move within a day.

What does a low compatibility score mean?

It is not a verdict on the relationship. A low score means the pair has more differences and understanding will take conscious work. Many strong unions are built on tense aspects.

Can I check compatibility with a friend or a colleague?

Yes. Synastry describes any relationship between two people: friendship, work, ties with parents. The communication and values areas are especially telling for friendships and shared projects.
