The origin and conversion of ancient time

It has been used since the Western Zhou Dynasty. In the Han Dynasty, they were named midnight, rooster crow, Pingdan, sunrise, eclipse time, Yuzhong, Rizhong, Riyun, Afternoon, Rijin, Dusk, Rending. It is also represented by the twelve earthly branches, with midnight to one o'clock as the Zi hour, one to three o'clock as the Chou hour, three to five o'clock as the Yin hour, and so on.

The origins of these words can be traced from ancient Chinese books in the pre-Qin period. Before the Han Dynasty, these titles were different. It was not until the Taichu period of the Han Dynasty that China implemented the Taichu calendar, "which divides a day into twelve hours, and uses the stems and branches as the rules."

There are twelve hours in a day. (One hour is equal to 2 modern hours), there are eight quarters in one hour (one quarter is equal to 15 modern minutes), there are three cups of tea in one quarter (one cup of tea is equal to 5 modern minutes), and one cup of tea has two sticks of incense (one stick of incense is equal to 2 modern minutes) 30 seconds), one stick of incense has five minutes (one minute equals 30 seconds), one minute has six fingers (one finger equals 5 seconds), and one finger has ten moments (one minute equals 0.5 seconds).
