What do 20 16, 1, 19 mean?

The picture below is a page from the old almanac.

The "liquidation" you asked is divided into two parts.

In order to choose auspicious days, the ancients formulated many methods to choose auspicious days, among which twelve satellites are a common one. Twelve satellites are twelve days of "construction, separation, fullness, leveling, determination, holding, breaking, danger, success, combination, opening and combination". For example, in the next year, the child will be built, the ugliness will be removed, and the number will go; Ugly year, build ugliness, divide yin.

The day you asked is the day when the twelve satellites are "closed".

Holding positions on duty, that is, this day is the "closed" duty of the twelve satellites, and the master has the final say.

The ancients stipulated different good and bad luck for each star. Among them, the "closed" star holds the sun. In most cases, it is not necessary to hold a happy event on this day. If it is used, it must be auspicious day, the virtue of heaven or the virtue of the moon. There are more auspicious gods than evil gods.
