What is the difference between the appropriateness and avoidance of a day in a perpetual calendar and the division of time?

The appropriateness and avoidance of a day in a perpetual calendar and the difference between minutes and hours represent different meanings. Twenty-four hours a day is divided into twelve hours. Every day from eleven o'clock in the evening, every two hours is an hour. Timing refers to what you can do at a certain time, and generally refers to doing something bigger, such as building a house, cooking, getting married, building a grave for the dead, etc. Avoid talking about things that you can't do at a certain time, such as the major events mentioned above. Time should be taken, avoided, but not used.
