How many hours and minutes did the ancients divide the day into?

The twelve-hour comparison table is as follows:

The names corresponding to the hours: Zǐ, U (chǒu), Yin (yín), Mǎo, Chen (chén), Si (sì), Wu (wǔ), Wei (wèi), Shen (shēn), You (yǒu), Xū, Hai (hài).

The twelve-hour system:

It was used in the Western Zhou Dynasty. In the Han Dynasty, it was named as midnight, rooster's crow, Pingdan, sunrise, eclipse time, corner of the center, mid-day, declining sun, Asr, sunrise, dusk, and people's fixing. It is also expressed by the twelve earthly branches, with twenty-three to one o'clock in the middle of the night as Zi Shi, one to three o'clock as U Shi, and three to five o'clock as Yin Shi, and so on.

In ancient China, people used the method of "copper pot dripping" to time the day and night into twelve hours, corresponding to today's twenty-four hours. The time between eleven and one o'clock in the middle of the night was called Zi Shi (子时), between one and three o'clock was called U Shi (丑时), between three and five o'clock was called Yin Shi (寅时), and so on.

When clocks and watches were first introduced to China, some people called an hour "Dashi", and a clock point of the new time "Hour". Later, as clocks became more popular, the term "Dashi" disappeared, while "Hour" is still in use today.

After the founding of the Republic of China, the use of the AD calendar year, month, day, hour, while retaining the Chinese lunar calendar, AD timekeeping, the day is divided into 24 hours, twice as small as the traditional twelve hours, so it is called the hour.
