Yinpan Qimen calculates hour, year and quarter-hour charts with optional manual bureau selection. Its nine-palace layout separates spirits, stems, stars and gates, using color to identify tomb, punishment and door-pressure conditions.
A header lists pillars, solar-term bounds, chief star and gate, xun head, horse, void and month general. Switch the late-Zi-hour convention and inspect the rule guide and color legend.
Save questions and notes, share images or text charts, and restore charts and conventions with a text code.
