What time is twelve?

The ancients divided a day and night into 12 periods, and each period was called an hour. Twelve o'clock can mean a day or any time. Twelve o'clock is the original creation created by the ancients according to the appearance and appearance of the sun, the change of the sky and the natural laws of their daily production activities and living habits.

Twelve hours include Zishi, Ugly Time, Yin Shi, Shi Mao, Chen Shi, Shi Si, Noon, Weishi, Shenshi, Youshi, Xushi and Shihai. During the Southern and Northern Dynasties, the twelve o'clock system was widely popular in China.

In ancient China, a day was divided into twelve hours, and on this basis, it was further divided to make the time more accurate.

There are twelve hours in a day. In modern times, one hour is two hours. There are 8 minutes in an hour, which is 15 minutes in modern times; 3 teas for a while, 5 minutes for a tea; A cup of tea has two fragrances, and one fragrance is modern 2 minutes and 30 seconds. A wick has five points, and modern wicks have 30 seconds; A point has 6 fingers, and one finger is modern 5 seconds; The snap finger has 10 moments, and an instant is 0.5 seconds.

There are different opinions about the origin of China's ancient twelve-hour theory. About before the Warring States period, in order to study the astronomical calendar, the celestial sphere was divided into 12 celestial regions along the equator, called 12 stars. At the same time, the north pole center of the sky is divided into 12 directions, and the time period is represented by twelve o'clock.

Twelve-hour system is a method of calculating time with twelve earthly branches. There is an algorithm of "pushing overtime" in Saint thomas lee, the oldest calendar in the Western Han Dynasty. The so-called "overtime" is to divide the conversion of time calculated by various calendars into twelve o'clock, which is the earliest record of the twelve o'clock system.

Wang Chong, a philosopher in the Han Dynasty, said in Lun Heng: "At twelve o'clock a day, the sun rises and rises." Explain that the names of twelve o'clock and twelve branch names have been used together and arranged in order.

In the Han dynasty, twelve o'clock was named as: midnight, crow, pingdan, sunrise, food time, corner, day, sunset, sunset, dusk, and people decide. Every hour has another name, which is represented by twelve branches.

Midnight, also known as midnight, midnight, midnight and midnight. The midnight is the first hour of twelve o'clock, corresponding to midnight, three drums and night C, and the time is from 23: 00 to 1: 00.

At this time, the earthly branch is called "Zishi". At this time, mice are active in the dead of night, so they are called "mice".

The period from darkness to light is called "night". "Midnight" refers to the middle period from dark to dawn, which is a natural phenomenon, and what people usually call "midnight" generally refers to all the dark time, which often exceeds the two hours referred to by "midnight".

Cockcrow, also known as pheasant. The second hour of twelve o'clock corresponds to four watches, four drums and midnight. The time is from 1 to 3 o'clock.

At this time, it is ugly to call the ground branch. Cattle are used to eating grass at night, and farmers often get up late at night to feed them, so they are called "ugly cows".

Chicken was praised by the ancients as "knowing when to keep an appointment". At dawn, the rooster crows, at dawn, people get up. "Cock crow" literally means "cock crows", but it refers to the period after midnight and before twelve o'clock Pingdan.

China is a vast country. Because of the different seasons and regions throughout the year, the time to start singing and dancing is generally about one hour before dawn in the local area.

Ping Dan, also known as Ming Dan, Dawn, Early Dan, Japanese Dan, Hidden Dan, Morning Dan, Early Dan, Early Dynasty, Hidden Shuang, Dan Day, and so on, is from 3: 00 to 5: 00, which is what we call the Five Watches in ancient times.

At this time, it was called "Yin Shi" by the earthly branch. At this time, the tiger lying in the daytime and walking at night is the fiercest. The ancients often heard the roar of tigers at this time, so they were called "Yinhu".

Before the sun came out of the horizon, the period before dawn was called "Pingdan", which is what we now call dawn.

Sunrise is also called sunrise, sunrise, sunrise, sundial, rising sun and dawn. The time is from 5: 00 to 7: 00, which refers to the time when the sun just appeared and Ran Ran first rose. At this time, the rising sun shines on the earth, giving people a feeling of vitality.

At this time, the earthly branch called it "Shi Mao". At first light, rabbits leave their nests and like to eat grass with morning dew, so they are called "hairy rabbits".

It is also called breakfast, feast and flea food when eating. The time is from 7: 00 to 9: 00, and the time for the ancients to "eat" is also breakfast time.

At this time, it is called Chen Shi earthly branch. At this time, it is generally easy to fog. In ancient China, it was said that dragons walked in the clouds and the sun rose, so they were called "Chen Long".

In the corner, it is also called Yu Ri, Yuzhong and Yu Ri. The time is from 9: 00 to 1 1, which is close to noon.

At this time, it was called "Shi Si" by the earthly branch. At this time, the fog cleared, the sun was shining, and a snake came out of the hole to feed, so it was called the "fourth snake".

Huai Nan Zi by Liu An in Han Dynasty? The word "corner" first appeared in astronomical training: "The sun rises in the valley." ... as for sangtian, it means eating; As for Hengyang, it is called a corner; As for Kunwu, it is exactly what you want. "

Duan Yucai, an exegetist of Chinese characters in Qing Dynasty, said that "the angle is an angle", so what is the relationship between this angle and time?

If we take Chang 'an, the place where Liu An, the author of Huai Nan Zi, and Su Fei, his disciples wrote books, as an observation point, people will find that Hengyang and Kunwu are both in the south.

When the sun runs over Hengyang, but not over Kunwu, the connecting line between Chang 'an observation point and the sun over Hengyang and the connecting line between the observation point and the sun over Kunwu form an included angle.

This included angle is the intersection angle between Shi Si and noon, measured with Chang 'an as the benchmark. That is, the east inclination angle formed by the sun between the beginning and the angle. Therefore, people call this period "Angle".

Japan and China, also known as Sun Zheng, the sun is at noon, the sun is high, at noon, the pavilion is at noon and the sun is at noon. The time is from 1 1 to 13.

At this time, the earth branch is called "noon". In ancient times, wild horses were not tamed by humans. At noon, they run around screaming, so they are called "afternoon horses".

The sun has moved to noon, which is noon. In ancient times, people used the time when the sun was in the center of the sky as a time mark to go to the market to trade. This commodity exchange was first conducted in Japan and China.

Sundial is also called sundial, sundial, sundial, sunset, sunset. The time is from 13 to 15, when the sun is in the west.

At this time, it was called "Wei Shi" by the local branch. In some places, it is called "sheep out of the slope", which means that it is a good time to herd sheep, so it is called "Weiyang".

The word "flying in the sun" was first seen in Historical Records by Sima Qian, a historian of the Han Dynasty. Tian Guanshu: "Dan eats it for wheat; Eating the sun is millet. " "sundial" means that the sun deviates to the west of the earth in the future. With the transit as the boundary, the sun at this time is opposite to the sun in the corner.

Time is also called time, day, millet and evening food. The time is from 15 to 17.

At this time, it is called "application for time" when it is called earthly support. At this time, the sun is setting in the west, and monkeys like to crow at this time, so they are called "Shen Monkey".

The ancients usually had a second meal at midnight. Therefore, the meaning of "time" is "the time of the second meal". The ancients often wrote "Yi" instead of "Yi Shi" in their works. For example, Du Fu's "Continued Steps" wrote: "All steps are green, and the court is in a hurry." Bai Juyi wrote in Su Du Qu Hua Xia: "I only regret that spring comes late and the day is sad."

Sunrise, also called sunset, sunset, sunset, sunset, sunset, dusk, dusk and evening, means when the sun goes down. The time is from 17 to 19.

At this time, the earth branch is called "unitary time" When the sun goes down, the chicken rotates in front of the nest, so it is called "unitary chicken".

"Sunrise" means that the sun sets, that is, the time when the sun sets. In ancient times, people regarded "sunrise" and "sunrise" as signs of the arrival of day and night respectively. At that time, people's productive labor and rest were based on the simple timetable of "work at sunrise and rest at sunset".

Dusk is also called sunset, sunset, sunset, evening, darkness, sunset, sundial and yellow. The time is from 19 to 2 1. At this time, the sun has set and it will be dark. The world is dark and everything is hazy, so it is called dusk.

At this time, the earth branch called it "Seven Stones". At this time, people have worked hard all day, and they are ready to have a rest. Dogs are called "dogs" because they lie in front of the door and bark loudly when there is any movement.

The ancients used "dusk" to represent this time because the sun was setting, everything was hazy and the world was dim. The word "dusk" vividly reflects the typical natural characteristics of this period. The word "dusk" was first used by Qu Yuan, a poet in the Warring States Period. In Li Sao, he wrote: "In the past, you and I were sincere and agreed that at dusk, we would take a different road and walk to the middle of the road."

The word "dusk" often appears in China's ancient literary works, especially in his poems. For example, Ouyang Xiu, a writer in the Northern Song Dynasty, wrote in "The Outline of Birth": "The willow shoots are on the moon, and people are about after dusk."

In this sentence, the poet uses "dusk" as a beautiful moment for young men and women to meet, which is extremely accurate. The well-known phrase "to see the sun, for all his glory, buried in the coming night" reveals the lamentation of Li Shangyin, a famous poet in the Tang Dynasty, and has been told by several generations.

People decide, also known as fainting at night. The time is from 2 1 to 2300.

At this time, it is called "stone sea" by the earth branch. At this time, in the dead of night, you can hear the sound of pigs arching the ground, so it is called "Hai Pig".

People must be the last hour of twelve o'clock in a day and night. Calm means quiet. At this time, the night is deep and people have stopped taking a rest.

The first long narrative poem "Peacock Flying Southeast" in China ancient folk songs has the poem "Lonely people will settle down after dusk". Knowing the concept of time, we can correctly understand the meaning of this poem.

In a word, the twelve-day chronograph is unique and has a long history. It is one of the splendid cultural treasures of China and an outstanding contribution of the Chinese nation to the astronomical calendar of mankind.
