A concise English guide to the deterministic calculation layer behind 1518 tools.

Reference boundary

1518 pages explain Chinese naming and folk-culture systems as structured references. They are not professional advice.

Calculation first

1518 separates deterministic calculations from interpretive writing. Stroke counts, five-grid numbers, BaZi chart data, zodiac relations, almanac rules, and astronomy-derived chart data are calculated before any explanation is written.

Known limits

Stroke standards, rare characters, simplified and traditional variants, and the academic status of Five-Grid naming remain debated. Use the result as a structured reference, not a final authority.
