The wheel is a figure, not an ephemeris. Locally computed values are marked. Give the prompt to any capable model — it will look up where the bodies actually stand and answer.

Cast the sidereal figure, copy the question

Grahas are placed against the fixed stars — ayanāṁśa subtracted, nakṣatra and pada named, Viṁśottarī counted from the Moon. Positions are computed here to a few arc-minutes and marked as such; the reading is not written here.

羅盤 · 玄空飛星 · 八宅

Twenty-four mountains on the 地盤正針, the 三元九運 boards, 山向飛星 with 替卦 and the 五黃 substitution, annual 紫白, and the 八宅 life-trigram directions.

optional · east positive · applied when the reading is true-north
立春-adjusted year · born before 立春 counts as the previous year
