Argue about who does things, and how?
One needs it done right away, the other when the mood strikes — and both are sure they’re right.
Two squares side by side — topics to talk about
Pythagorean Square: compatibility by birth date — calculate online
One needs it now, the other later — and both are right. The squares show where you’re alike, where you differ and where to start the conversation.Where you’re alike, where you’re not — and what to talk about

Eight lines side by side
Compatibility line by line
Where the sums are close and where they differ: the rows, columns and diagonals of two grids, with a question for each line worth asking each other. For now — an example couple; enter your dates above.

Start with what you argue about
Which argument is about the two of you?
Choose the one that feels closest: we’ll show which line of the two squares to compare and which question to ask each other. It’s an example, not your couple’s result.

What you can test
Ask each other: “What time of day is it easier for you to take on chores?” — and compare the answers.
The “Chores” argument leads into the chapter "Practicality, home life and work rhythm" of the full comparison. Compare the squares — and this line opens on your own dates.
A comparison, not a verdict
How to read the differences
The formula has no compatibility score, so the reading looks only at the difference in each line’s sums — no percentage and no verdict.
Sums are close
Similar marks from the model. Not a guarantee of agreement: equal sums show up in different ways, so check them against examples from your own life.
In the example: 1 of 8 linesSlightly apart
A slight gap in the marks — a good reason to ask each other how each of you sees this theme, without sorting out who’s right.
In the example: 2 of 8 linesNoticeably apart
A contrast of marks, not a forecast of conflict: for some couples the difference helps, for others it gets in the way — and only your experience knows which.

How to calculate compatibility by birth date
Each of the two gets their own square: additional numbers, nine cells, eight line sums. Then the sums of the same line are placed side by side. A difference of 0–1 counts as close, 2 as small, 3 or more as noticeable, and cells differing by two repeats or more are flagged separately.
What else to compare together
Which cells make up each line and which sums come up more often — on the lines page.

Questions about compatibility
Can I compare two squares for free?
Yes: both grids, the sums of eight lines and a short gist of the couple open with no payment. The full comparison with a question for each line is optional.
Will you show a compatibility percentage?
No. The square formula has no canonical compatibility score, and we won’t invent one. How to read the difference in sums is in the “How to read the differences” section.
How do I calculate compatibility between a man and a woman by the Pythagorean Square?
Enter both birth dates: a square is built for each, then the sums of eight lines are compared. Gender plays no part in the formula — the calculation is the same for any pair.
Can I compare people who aren’t partners?
Yes: friends, relatives, colleagues — any two birth dates.
What if almost all our lines differ?
That’s common: two random dates rarely have matching line sums. Differing marks aren’t a forecast of conflict — they’re a list of topics that are handy to start talking about.
Arguing about the same thing?
Start with one line and one question
Enter two birth dates — and it becomes clear which topic to start the conversation with.
