Why trust these numbers? Because you don't have to. Every result carries a fingerprint
(engine version + ruleset + input digest) that anyone can recompute and check — in your browser
or via the public API. The engine's calendar output is machine-cross-checked against the
Hong Kong Observatory for 1901–2100, with every known divergence
attributed in the accuracy report and the
public errata. We make no predictions — this is a calculation tool for a
cultural tradition, and we show our work.
