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

危為燕

危 is the swallow.

協紀辨方書 卷一

About this entry

The swallow is assigned to this 危 in 協紀辨方書 卷一, as a creature likened to the rat at the 子 palace's center. The character is the same as that of the officer 危, Danger, and the two are unrelated: one counts twenty-eight days and the other twelve.

星厯考原 卷五 writes the moon group as 危, 畢, 張 and 心, and modern practice gives the moon Monday. It stands between 虛 and 室. Its only rating is in the appendix at 協紀辨方書 卷三十五, which keeps an older rule that 心, 危, 畢 and 張 days are favorable in spring and autumn for making and consecrating images of deities.

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.
