Pythagoras Square: Calculating the Psychomatrix

How to build the Pythagoras square from a birth date and what each 3×3 cell means.

The Pythagoras square, or psychomatrix, is one of the best-known numerological methods. It breaks down a person's character into nine qualities based on the date of birth. You can build the square right now: the Pythagoras square online is free and needs no registration.

How the square is built

First, four working numbers are calculated from the date of birth: all the digits of the date are added, then the sum of its digits, then a special formula gives the third and fourth numbers. All the digits of the date and the working numbers are gathered into one string, and the count of each digit from 1 to 9 is tallied. These repetitions fill the cells. Our service calculates instantly.

What the nine cells mean

Each cell governs a quality: 1 is character and will, 2 is energy, 3 is interest and talents, 4 is health, 5 is logic and intuition, 6 is work, 7 is luck and giftedness, 8 is a sense of duty, 9 is memory and mind. The more identical digits in a cell, the more strongly the quality is expressed.

How to read the result

For example, “111” in the first cell speaks of a strong, confident character, while its absence speaks of softness and flexibility. Empty cells are not a flaw but areas of growth: qualities you can consciously develop. Clicking the cells, you will read a detailed interpretation of each.
