Why don't ordinary books in society (books devoted to auspicious days) match the auspicious days found on the Internet?

There are many ways to choose a day, such as the arc angle star method, the special method, the big Liu Ren method, the three-in-one method, the divination method, the Zhouyi divination method, the Heluo counting method, the positive five-element method, and of course the god killing method.

Different theories lead to different results. Personally, I think the special method of choosing a day is the most reasonable.
