Time Calculation in Zhouyi

It's kind of like four pillars looking for god. First of all, you should know what five elements are most beneficial and helpful for your measurement, and it will be easy to succeed in the month where the five elements belong. Generally speaking, it is mainly based on months, supplemented by years. It is entirely possible to get the date accurately, but at least I can't do it myself. Also, the hexagram itself represents the number, and the specific number or time should be finally judged according to the relationship between the main hexagram and other hexagrams. These all need a lot of practice and verification, but also calm down.
