MingXu: compute the chart, then see its structure and time

MingXu is a free, local-first traditional Chinese-metaphysics calculator. Fixed code generates BaZi, Zi Wei Dou Shu, transit, true-solar-time and Da Liu Ren structures; you can then copy the evidence to ChatGPT, Claude, Gemini or another AI for interpretation.

How it works

1. Enter birth or casting details with an explicit time basis.
2. Generate reproducible chart structures and boundary warnings.
3. Copy Markdown, plain text or JSON.
4. Ask the AI you trust to explain the computed evidence.

Core tools

• Free BaZi chart: Four Pillars, Ten Gods, luck cycles and true-solar-time comparison
• Zi Wei Dou Shu chart: twelve palaces, transformations and dynamic periods
• Da Liu Ren chart: Four Lessons, Three Transmissions, Nine Schools and void branches
• True solar time calculator: longitude correction, equation of time and boundary checks
