When did the year of divination begin?

Speaking of divination, especially in the past, divination is still very important in Chinese folklore. Almost many people believe in divination. Although not necessarily dedicated, I still believe, especially in the embarrassing season every year. Of course, diviners are really busy, and this is also the time when their income is the highest. So when does luck start every year? Usually in the first month, just after the Spring Festival. This is the time to calculate the fate of a person and a family for one year. In rural areas, it is of course a psychological desire to pay special attention to this year's harvest.
