Time superstition in the yellow calendar

According to the lunar calendar, the Book of Changes, the Book of Hutuluo and the 24 stars in heavenly stems and earthly branches. The yellow calendar is based on the China lunar calendar, and many calendars show the good or bad luck of a day. That is, the ancients recorded their daily likes and dislikes on the calendar as a guide to action. For example, it is not appropriate to break ground today, but you can move tomorrow and start a new stove the day after tomorrow. Laohuangli is a derogatory term, which means superstition. So is there any scientific reason?

It does make sense. At least based on the concept of statistics, the Gregorian calendar is worthy of scrutiny and testing. There is no denying that the ancients were superstitious. However, the ancients were not idiots. Many experiences in the yellow calendar are summed up through a lot. From generation to generation, the application is consistent with the natural phenomena of heaven and earth and human society. This is the essence. The theoretical basis can be found in a very important book "Jieji Frontier Defense Book" in the Kangxi period.
