How to read your stack
Each card names its tradition: Western astrology, the GIA and US trade birthstone lists, Chaldean and Pythagorean numerology, and Mary K. Greer’s tarot birth card method. The traditions are separate systems, and they do not agree with each other. No study shows that a birth date, a number, a stone or a card predicts anything about a person. If a reading feels accurate, that is partly the Barnum effect, which our test lets you try on yourself.
Our own checks: we ran the date logic over every valid date from 1900 to 2026. This tool is our own build and uses no outside service.
