How the Five Elements Crystal Quiz calculates a result

The free result is deterministic, not a live guess from generative AI. The same input on the same mapping version produces the same element, color, and material direction.

Four calculation steps

  1. Build the active pillars. The civil birth date supplies the year, month, and day pillars. The hour pillar is included only when a two-hour period is entered.
  2. Score day-master strength. The month season has the largest weight. Stems and branches then add or subtract support. A score of 145 or more is strong, 55 or less is weak, and the middle range is balanced.
  3. Choose the leading element. A weak day master uses the generating element, a strong one uses the element it controls, and a balanced one uses the element it generates.
  4. Map to jewelry. The leading element supplies the primary colors and materials. The upstream generating element supplies a secondary direction. Visible color wins when stone classifications disagree.

Inputs and limits

Required
Civil birth year, month, and day.
Optional
A Chinese two-hour period. Without it, the hour pillar is excluded and the result is marked date-only.
Not used
Gender. It only changes a luck-cycle direction that this product does not use.
Time zone
Version 1 uses the entered civil date. It does not convert birthplace time zones or change the date at late Rat hour.
Boundary day
A solar-term boundary triggers a visible note and a wider margin in the detailed explanation.

Claims and responsibility

Chinese Five Elements is a traditional cultural framework, not medical, psychological, or financial diagnosis. Crystal folklore is separated from mineral facts and is never presented as a health effect or guaranteed outcome.
