Altitudes, directions and the Moon's lodge are computed on-device for SCOB (1.3342°N, 103.7357°E) at the chosen moment (Moon position via the shared astro-core.js engine), so the page works offline. Each mansion is shown by its marker (determinative) star. The 🌙 lodge is the Moon's real position among the stars; the 📅 almanac value is the separate calendar mansion (a fixed 28-day cycle for date-selection, matching the Japanese koyomi), which drifted from the sky long ago — the two rarely agree. For what each mansion means, see The Chinese Sky.高度、方位與月宿皆於本機為 SCOB（1.3342°N，103.7357°E）依所選時刻推算（月位用共用 astro-core.js 引擎），離線亦可用。每宿以其距星表示。釋義見 中國星空。
