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 old almanac, we all know that it is also called the imperial almanac, Tong Sheng and so on. It is a kind of calendar that can combine Gregorian calendar, Lunar calendar and various auspicious and evil spirits at the same time, so it is often called a general book in our country, or it is called a smooth boy 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." It is easy for me to understand here. Basically, it is to use the time of a thing, and then find out its date and column at this time, just like the "eight characters" we often say, and then make a symmetrical interpretation through the 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 ultimately comes 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 delve into the accuracy of this, then I think what you should do is that a large number of statistics are consistent. 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 and make 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!
