Yes. A compatibility reading, or synastry, compares two birth charts, and the method is the same for every kind of bond: it works for a friend, a parent, a child, a sibling or a colleague as well as for a partner. What changes is what you look for. Between friends you look at how you talk and back each other up; in a family, at care and old patterns; at work, at how you share tasks and decisions.
How does synastry work for any two people?
Both birth charts are calculated from each person's birth date, time and place. Then each planet in one chart is compared with each planet in the other. When two planets form an angle, such as a conjunction, a trine or a square, it shows a link between you: easy, lively or tense. Where your planets fall in the other person's houses shows which area of their life you touch.
What does it show for each kind of bond?
| Bond | What matters most | Where astrologers look |
|---|---|---|
| Partner or love interest | Attraction, affection, commitment | Venus, Mars, the Moon, the 7th house |
| Friend | Shared interests, talking, trust | Mercury, Venus, Jupiter, the 11th house |
| Parent, child or sibling | Care, emotional needs, old patterns | The Moon, Saturn, the 4th house |
| Colleague or business partner | Working style, decisions, shared goals | Mercury, Mars, Saturn, the 6th and 10th houses |
The aspects between the two Suns and the two Moons matter in every bond: they show how your identities and your emotional needs meet.
Do you need both birth times?
They help. The birth time gives each chart its Ascendant and houses, so the reading can say where you land in each other's lives. Without one or both times, every planet and aspect can still be compared, and the houses are left out. See do you need your exact birth time?
How do you get a compatibility report for a friend or a family member?
Our compatibility report asks who the other person is to you: a partner or love interest, a family member, a friend, or a colleague or business partner. The report follows your answer: for family and friends the love chapter becomes care and support, for colleagues it becomes working together, and the text never treats the bond as romantic.
It is a PDF of over 20 pages for $9.90, paid once with no account: both charts' positions side by side, the aspects between you, the houses you light up in each other's lives and written chapters on how you get along. You see both Big Threes and the first pages free before you pay, with a 14-day money-back guarantee. Start one for a friend, a family member or a colleague.
Should you ask before using someone's birth details?
Yes. A birth time is personal, and many people do not know theirs. Ask first, and share the report only if they want to read it. Our report goes only to you: the other person gets no email.
Astrology is for reflection and self-understanding. A compatibility reading can help you talk about how you relate, but it cannot decide whether a bond will work.
