How did the ancients describe the date and time?

In addition to the general use of dry branches, the ancient people also used a certain month and day to express the date. The way to express the date should be "the first day of the month", such as "the ninth day of September" and "the first day of October", which should be the same as today's lunar calendar.

Time is expressed as 24 hours every day and night, which was 12 hours in ancient times. When western mechanical clocks and watches were introduced into China, people called the time points of China and the West "Da Shi" and "Shi Shi" respectively.

Extended data:

In ancient times, time represented time. Time is divided by people according to the movement of matter, not inherent. There is no time in the universe. Material movement takes time,

But if we don't divide "time" into spaces, our minds can't know "time". The reason why we can think is that thinking can name the material world, while things are real, thinking is empty, and thinking about life and things is empty. An undivided "time" cannot be named and distinguished. Only by dividing it into "time" can it be used by thinking, because it can only be named after division.

For example, we divide the earth's movement around the sun into one year and the earth's rotation into one day, which is convenient for thinking to calculate with digital symbols. If you don't live on the earth, you will never divide time by the movement of the earth.

Therefore, time is only a division of material movement for the convenience of thinking about the universe. This is a man-made rule, not a natural rule. The room is artificially divided, so you can divide it at will.
