Two birthdays, one score written for friendship - the relationship people work out by instinct and rarely think about directly.
Enter two birthdays and a relationship type to get an easy-to-read compatibility report with printable details.
Friendship is the relationship people are least likely to analyse and most likely to lose by accident. Nobody has a difficult conversation about a friendship the way they do about a marriage. It just gets quieter, and then it is a birthday message once a year.
The friendship score carries a modest positive modifier: friendships are chosen, so they start with goodwill, but they have no structure holding them together when life gets busy. What the sign pairing tends to describe is the mechanism by which a particular friendship stays alive. Air and fire pairs run on shared activity and new plans. Water and earth pairs run on availability and consistency. When those two types are friends with each other, the usual complaint - on both sides - is about effort, when it is really about format.
Read the communication category first. It is the one that most often explains a friendship that everybody agrees is good but that neither person quite maintains. Two people who both wait to be invited will drift no matter how well matched they are on everything else.
This is also the least loaded page here, and a good one to run first if you have never used a compatibility calculator. There is nothing at stake in finding out that you and your closest friend score a 71.
If you are checking a friendship that has become family - the friend at every wedding, the one your children call an aunt - it is worth running the family relationship types too, and seeing which one the score is closest to.
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.
Yes. The relationship modifier and the written insight both change, so the same two birth dates produce a different score and a different interpretation for friends than for partners.
The family zodiac chart takes several birthdays at once and works just as well for a friendship group as for a household.
You need the day and month at minimum, because signs change mid-month. Birth time and place are not used anywhere in this calculator.
