Ritual date selection

How did it begin?
Ritual references use traditional 祭祀 entries. Unlike other activities, exceptions for month break or four wastes alone are distinguished from prohibitions when influences overlap. Only entries already supported by the calculator are selected from Volume 11’s activity lists and Volume 10’s officer and influence explanations. Concurrent favorable and prohibited references produce caution; favorable alone produces a favorable reference; neither produces no determination. No determination does not mean a favorable day. This is a partial reference, excluding other influences, lunar-day restrictions, directions, hours and personal birth charts, rather than the complete selection and mitigation procedure.
Calculation rules
祭祀. Favorable references: Heavenly virtue (天德) · Monthly virtue (月德) · Heavenly virtue combination (天德合) · Monthly virtue combination (月德合) · Heavenly pardon (天赦) · Full (滿) · Open (開). Caution references: Severe yin-yang meeting (陰陽會衝) · 寅日. Ritual is not prohibited by month break or four wastes alone. Their overlap produces caution. Universal restrictions apply without the four virtue/virtue-combination influences when month break overlaps disaster sha or monthly punishment, monthly sha overlaps level/close officers, or the specified months combine monthly punishment with level/receive officers. Monthly aversion with month break and disaster sha remains caution even with virtue combinations; 子/午-month establish-officer aversion is caution without heavenly pardon. 寅 days and the specified heavenly-dog condition also apply. Only entries already supported by the calculator are selected from Volume 11’s activity lists and Volume 10’s officer and influence explanations. Concurrent favorable and prohibited references produce caution; favorable alone produces a favorable reference; neither produces no determination. No determination does not mean a favorable day. This is a partial reference, excluding other influences, lunar-day restrictions, directions, hours and personal birth charts, rather than the complete selection and mitigation procedure. The day pillar follows the device’s local date and midnight (00:00). Activity references display precomputed data using Korean Standard Time solar-term months for 2020–2050; dates outside the range are not estimated. This differs from lunar conversion support, 1000-02-13 through 2050-12-31.
