Auspicious Date Calculator (택일)

Korean 택일 (date selection), not a generic lucky-day list. Every day in your window is read by its 일진 (day pillar) — the 건제십이신 (twelve day-officers) for what you actually intend to do, the 황흑도 (auspicious/inauspicious path) 신 (spirit) ruling it, 손 없는 날 (spirit-free days), and how the day sits against your own 사주 (Four Pillars chart). The good days for a wedding are not the good days for a burial, and this tells them apart.
