There are today's taboos on the calendar. How are these inferred?

There are some inferences in the calendar mentioned here that should be avoided today. I think that should be to ask the mystery of the old almanac, that is, "Japanese class" Speaking of the ancient yellow calendar, we all know that it is also called the imperial calendar, the children's calendar and so on. It is a calendar that can integrate the solar calendar, the lunar calendar and all kinds of good and bad luck at the same time, so it is often called a general book among our people, or it is called a childlike innocence and fluency because of accent and scruples.

As for the quality of choosing a day, we should avoid today, and so on, that is, its inference method, usually called "day class." Here, I can easily understand that it basically uses the time of a thing, and then finds out its date and column at this time, which is like the "eight characters" we often mention, and then interprets it symmetrically through information such as heavenly stems and earthly branches in the eight characters. Of course, there are many necessary factors and decisive conditions, because we are not professional, so we can't elaborate.

Let's put it this way here. If you summarize it in one sentence, find out the information derived from the event "eight characters". As for the quality of this information, it will eventually come down to the keywords displayed on the Gregorian calendar. I think this is probably equivalent to the situation that we often get the final figures after large-scale calculation. Of course, if you want to study the accuracy of this point in depth, then I think what you should do is a lot of consistent statistics. At present, we really don't have such a statistical department doing such a thing.

Of course, we are all a new generation of young people with knowledge and culture who grew up under the red flag and walked in the spring breeze, so we should divide some knowledge left by our ancestors into two parts for in-depth analysis and research. At present, the information I can find and the understanding of its principle are only so. Finally, I look forward to getting more professional supplements. Thank you!
