Compare two cousins' birthdays for a score written around the family relationship that behaves most like a friendship.
Enter two birthdays and a relationship type to get an easy-to-read compatibility report with printable details.
Cousins occupy an unusual position. You are given the relationship the way you are given a sibling, but you get to decide almost everything about how much of it you use. Some cousins are effectively siblings. Others are people you see at weddings and like enormously for four hours a year. Both are normal, and the calculator scores the pairing accordingly - a small positive modifier, closer to friendship than to family obligation.
What the sign comparison is good for here is predicting which of those two versions you are likely to end up with. High-scoring cousin pairs tend to close the distance themselves; they text between the weddings. Lower-scoring pairs are usually perfectly warm in person and simply never become the ones who organise things together. That is not a failure of the relationship.
Cousins also sit at the point where two branches of a family meet, which makes them the most interesting pairing in the whole calculator from a genealogical angle. Your cousin has half your grandparents and none of your parents. Whatever the two of you have in common comes from a specific, identifiable place further up the tree - and whatever you do not share came in from the outside, through the parent you do not have in common.
If your family is large enough that you have first, second, and once-removed cousins, the relationship type is the same for all of them. What changes is how much shared history is available to absorb friction, which is exactly what the challenges section is describing.
Run it against several cousins in one sitting. The comparison across a whole generation is where this becomes interesting rather than a single number.
Each relationship type is scored differently, because each one carries a different amount of shared history.

Two birthdays, one honest look at the pairing
The calculator uses a local zodiac engine and deterministic compatibility rules so the same dates always produce the same report.
Not to the calculation, which uses two birth dates and the cousin relationship type. If you want to work out the exact degree first, the cousin calculator does that from how you are each connected to a shared ancestor.
Because the relationship behaves like one. Cousins carry a small positive modifier - more shared context than a friendship, far less daily friction than a sibling.
The family zodiac chart is built for that - several birthdays together, the sign spread across the group, and the pairings at each end of the range.
One chart for the whole family - every sign, the dominant element, and the pairings at either end.
