Cardology’s Quadrations

How to Use the 90 Quadrations Calculator

This calculator is based on your year of life, not your chronological age. It begins with Year 1, meaning it counts the first year of life rather than completed birthdays. For example, if you are 62 years old, you are living your 63rd year of life. Therefore, to interpret your current year, select the 63rd Quadration, not the 62nd.

A simple rule to remember: Add 1 to your current age to find your active Quadration.
