Built for learning and cross-checking
These subjects mix calendar work, directions, stems and branches, and step-by-step rule sets. When you study on your own, hand copies are slow and books disagree; the same birth data or bearing can fork mid-calculation and become hard to compare. Tools here lay the chart out on screen under the common rules, so you can rerun the same input and line it up with a textbook example, class notes or your own workbook.
Topic articles and guides live elsewhere on the site and can be read beside a tool; this page lists only the calculators you can run directly. For any one subject, start with what each field means and which rule step each line on the chart represents, then compare your sources. That beats memorising a conclusion without checking the working.
What the platform does
It turns teachable rules into reproducible charts on the web. Each tool lists its inputs, outputs and the common rule set it uses, so you can compare book wording or see whether a claim holds under those rules.
Limits
Charts do not give personal verdicts on money, health, marriage or moving house, and they are not medical, legal or financial advice.
Tools available now

Names
Calculation basis
Calendar work can be checked against any published perpetual calendar. Pillars, hexagrams and directions use one shared common rule set site-wide.
