Compatibility Calculator
The compatibility calculator combines data from two people — birth dates and names — and shows how popular numerological tradition describes their union: life path numbers of both partners, common contour zones of the Pythagorean Square, and a final verbal scale ranging from neutral to high.
The content on this site is for entertainment and educational purposes only and does not constitute medical, psychological, or financial advice. The compatibility calculator is a modern popular practice: life path numbers by birth date, name numbers by Pythagorean letter table, common contour lines of the Pythagorean Square by Alexandrov. Number pair comments are based on Cheiro's school (Chaldean, with Sepharial's refinements); in the same Cheiro school, master numbers 11/22/33 for pair comments are reduced to the base: 11→2, 22→4, 33→6. No direct historical continuity with the ancient Pythagorean school has been established.
How the calculator works
Each partner's life path number (destiny number) is calculated from the birth date: all date digits are summed and reduced to 1–9; master numbers 11, 22, and 33 are not reduced and are preserved as-is. The name number is calculated using the Pythagorean letter-to-number table: each letter corresponds to a number 1–9 (Russian names are first transliterated to Latin using the passport scheme), and their sum is reduced the same way. By Cheiro, master numbers 11, 22, and 33 for pair comments are additionally reduced to the base: 11→2, 22→4, 33→6.
The second axis is the common contour of the Pythagorean Square (psychomatrix by A. F. Alexandrov): the date and name digits of both partners are combined into a single 3×3 square, and its lines (1-4-7, 2-5-8, 3-6-9, 1-2-3, 4-5-6, 7-8-9, 1-5-9, 3-5-7) are used to evaluate union zones: the more digits in a line, the more strongly the zone is expressed.
The final scale is verbal: high, medium, or neutral compatibility. The method is a modern popular practice developed from the Pythagorean letter table and Alexandrov's work (psychomatrix); no direct historical continuity with the ancient Pythagorean school has been established. It does not provide exact recipes: it is an entertainment and educational tool, not a scientific forecast.
