Method Used in This Tool

This is a learning tool, not a claim of one true method.

Xiao Liu Ren has multiple casting traditions. This tool currently uses one fixed method for learning consistency: the lunar month-day-hour method. Other teachers or traditions may count differently, use different timing rules, or interpret palace positions in different ways.

Formula

Month Palace = (lunarMonth - 1) % 6

Day Palace = (monthIndex + lunarDay - 1) % 6

Hour Palace = (dayIndex + hourNumber - 1) % 6

Check: (lunarMonth + lunarDay + hourNumber - 3) % 6

Rules

Leap lunar months use the same month number.

23:00-23:59 is treated as Zi hour within the selected civil date. It does not automatically move to the next civil date.
