Day spirit

Golden Casket
An almanac describes traditional day-types. It cannot decide health, money, law, marriage or children. Burial, marriage and medical items on these pages are what a book states, never advice.
In the classical sources
金匱石室以藏先王之訓典法式之所在也
The Golden Casket is a stone chamber where the instructions and models of former kings are stored.

About this entry
Fifth on the list and yellow, 金匱 starts at 辰 in the first month. 曹震圭, in 協紀辨方書 卷七, calls it the emperor's storehouse of treasures, and he supplies the other name 天寶.
The 1741 editors give a drier reading. A line from 春秋合誠圖 lets them seat the casket at 午, as the place that keeps the records and models of earlier rulers. 星厯考原 卷五 simply lists the spirit and states its counting rule, which is the rule the calculator uses.
Where this text comes from
The Chinese follows the Wikisource typed text of the Siku copy, under its CC BY-SA terms. Statements about the calculator describe its own rules, and modern practice is labeled as modern.
The English here is our own plain wording. Lists keep the items of the source.
