This event has no sitting/placement — 坐山 criteria (日→坐山, 三煞, 五黄, 岁破, direct crash vs 坐山) are excluded.

Birth-year pillar honours the 立春 boundary.

Default (unchecked): the main person is mandatory; the rest are preferred. Dates matching everyone appear first (most auspicious), then main-only dates as fallback.
