Why are there seven days in a week?

From the bible.

Genesis in the Bible records the process of God creating the universe. On the first day, God created light, on the second day, he created air and water, on the third day, he created land, sea and all kinds of plants, on the fourth day, he created day and night, festivals, days and years, on the fifth day, he created all kinds of animals, on the sixth day, he created man in his own image, and on the seventh day, when he finished his work, he rested.

This has become the origin of seven days a week and Sunday rest.

Sunday, also known as "Sunday", is also a day to commemorate the resurrection of Jesus. In the past, Jesus came to the world to preach the truth of God, teach people, help and heal the sick, but those who didn't believe in him crucified him. On the third day after his death, on Sunday morning, he rose from the dead. At that time, his disciples Mary, Jonah and all the believers living in Jerusalem witnessed Jesus' resurrection from the dead. They know that Jesus is the real living Redeemer, full of joy and hope.

Today, no matter where people believe in Jesus, seven days count as a week, and most sundays are off. It conforms to the principle that God created heaven and earth on the sixth day and put down his work and rest on the seventh day. It also reminds us that Sunday is a day to commemorate the resurrection of the Lord Jesus for our death.

"7" is a magic number. Why do humans use this number as a time period? Why not "10" or "12"?

Because ancient humans didn't know the progressive system, it was very difficult to understand numbers. Every natural number must have a pronunciation, which is obviously impossible for ancient humans who are not very rich in language. Therefore, they can only recognize smaller natural numbers.

In ancient times, human beings were very mysterious about the ebb and flow of tides and the ebb and flow of the moon. The high tide and the disappearance of the moon are very regular. At high tide, it takes 7 days from the midline to the highest tide position; It takes 7 days to return to the midline position from the highest tide position. Low tide: it takes 7 days from the midline position to the lowest tide position; It takes 7 days to recover from the lowest tide position to the midline position. Seven days is the period of ebb and flow.

For the moon: from half moon to full moon, the time is 7 days; From the full moon to the semi-circular moon, the time is 7 days. From half a month to disappearance, the time is 7 days; It's seven days from disappearing to half a month. Seven days is also the cycle of moon's profit and loss.

The ancients didn't understand that tides were caused by the moon, but they found the laws and connections. The ebb and flow of the tide, the full moon and the lack of the moon are synchronous, and they are all four 7 days. Since the decimal system was not used, the ancients did not represent the number 28, so they chose the number 7. Because the observation of the moon belongs to the observation of astronomical phenomena, similar to the observation of the sun and stars, it is called a week, and the cycle means cycle. The Chinese pronunciation of "7" is homophonic with the beginning, end, period and song, which means reciprocating, that is, reciprocating. 7 is the cycle of the moon's gain and loss in astronomical phenomena, which corresponds to the number of days, while 10 only corresponds to fingers, which is not astronomical phenomena, which the ancients could not understand and accept; 12 is not a cycle, and there is a big mantissa after 12. In addition, 12 exceeds 10, which ancient humans could not express before the progressive system.

Why is a week seven days? Who ordered it?

Week, also called week or worship, is a unit of time created by the ancient Babylonians, and a week is seven days.

The origin of the week should be the cycle connected with the moon, because seven days is about a quarter of the moon's week. Later, the Jews spread it to ancient Egypt and from ancient Egypt to Rome. After the 3rd century, it spread widely to European countries. In the late Ming Dynasty, it was introduced into China with Christianity, so it was called worship.

From a religious point of view, the Bible believes that God created everything in the world in six days, and rested on the seventh day. The seventh day began on Sunday, and the seventh day was Saturday, so Judaism took Saturday as the Sabbath. After Christianity became the state religion of ancient Rome, because Jesus was resurrected on Sunday, Sunday was changed to Sunday; * * * thinks that * * * completed the creation work on the sixth day, which should be celebrated, so Friday is designated as the Sunday of major worship. But in any case, international standards have defined a week as the first day of the week.

Why is there only seven days in a week?

Originally from the Bible-Genesis, it records God's creation work, saying that light was made on the first day, air and water on the second day, land, sea and various plants on the third day, the sun, moon and stars on the fourth day, day and night, seasons and years, animals on the fifth day, people in their own image on the sixth day and people on the seventh day. This has become a Sunday that has been passed down to this day. Monday, Tuesday, Wednesday, Thursday, Friday and Saturday have seven days in a week.

Now all countries in the world use the system of seven days a week-this system was first formulated by Constantine the Great. On March 7th, 32 1 year, he officially declared seven days as a week, and this system has been in use ever since. The English names of seven days a week are Sunday, Monday, Tuesday, Wednesday, Thursday, Friday and Saturday. These names originated in Babylon, Cuba. In the 7th and 6th centuries BC, the Babylonians had a weekly system. They divide a month into four weeks, and each week has seven days, which is a week. Babylonians built seven-star altars to worship the stars. The seven-star altar is divided into seven layers, and each layer has a star god. There are seven gods from top to bottom: sun, moon, fire, water, wood, gold and earth. God is in charge of one day of the week, so he sacrifices to a god every day, and every day is named after a god: Chamakh, the sun god, is in charge of Sunday, which is called sunny day; The moon god Xin is in charge of Monday, called the moon day; Niga, the god of Mars, is in charge of Tuesday, which is called the bright day of fire; Naboo, the god of mercury, is in charge of Wednesday, which is called Water Rong Yaori. Duke, the god horse of Jupiter, is in charge of Thursday, called Mu Yaori; Istar, the god of Venus, is in charge of Friday, called Jin Yaori; Saturn's god Ninuda rules Saturday, which is called the Rong Yaori of the Earth.

The weekly system founded by Babylonians first spread to ancient Greece and Rome. The ancient Romans named 1 week and 7 days after the gods they believed in: Sun Day, Moon Day, Mars Day, Mercury Day and Jupiter Day. After the name spread to Britain, the Anglo-Saxons changed four of them with their own names of gods, replacing Mars Day, Mercury Day, Jupiter Day and Venus Day with Wednesday, Thursday and Friday respectively. Tuesday came from Tiu, the Anglo-Saxon god of war. Wednesday comes from Walden, the highest god, also known as the Lord God. Thursday is from Raytheon. It's Raytheon. Friday comes from frigga and is the goddess of love. This forms the names of 1 7 days in English today: Sunday (Sun God Day), Monday (Moon God Day), Thursday (God God Day), Thursday (Raytheon Day), Friday (Love God Day) and Saturday (Land God Day).

In ancient times, people regarded the sun, the moon, Venus, Jupiter, Mercury, Mars and Saturn as the seven gods, which were called the seven gods. They think they take turns to dominate the day on earth. For example, the first day is dominated by the moon god, which is called "moon day" and the seventh day is called "sun day", so every seven days is a week, which is a week.

The current seven-day week system originated from the two river basins in ancient West Asia. In the 7th and 6th centuries BC, during the Assyrian Empire and the New Babylonian Kingdom, Babylonians began to take the week as the basis. They divide a lunar month into four weeks, and each week has seven days. This is a week. This is because the Babylonians had a building dedicated to the stars, which had seven floors and was called the Seven-Star Altar. There are seven star gods from top to bottom, namely, the sun, the moon, fire, water, wood, gold and earth. The Babylonians believed that the seven stars were on duty in turn, and each was in charge of a day. They worship a god every day, and every day they are named after a star god. The sun god Chamakh is in charge of Sunday, which is called Sun Obsidian Day. Moon God Xin is in charge of Monday, which is called Moon Yao Day. Niga, the god of Mars, is in charge of Tuesday, which is called Fire Obsidian Day. Naboo, the god of mercury, is in charge of a week. ......

What do you mean there are seven days in a week?

The origin of seven days a week is generally related to the genesis in the Bible, that is, God works for six days and rests on the seventh day. However, there is evidence that the Jewish concept of weeks may come from the Semites and Babylonians in Mesopotamia in southwest Asia, who divided the year into weeks.

The origin of the seven-day week is generally related to the genesis in the Bible, that is, God works for six days and rests on the seventh day. However, there is evidence that the Jewish concept of Zhou may have originated from the Semites and Babylonians in Mesopotamia in southwest Asia. They divide the year into several weeks. There are seven days in a week, one of which is a rest day. As early as Babylonian times, the sun and the moon matched the five known planets at that time to record the sun, and seven days was a week. The Romans used this habit of timing, but it was later changed to eight days. It was not until 32 1 year that Constantine the great included seven days in the Roman calendar and set Sunday as the beginning of the week.

In many cultural languages, every day of the week is related to celestial bodies. In western languages, from Sunday to Saturday, they are named after the sun, the moon, fire, water, wood, gold and earth respectively. In the ancient calendar of China, 28 nights were allocated every month, and seven nights were also used as weeks to record one day, so was the arrangement order of celestial bodies. To this day, Japanese and Korean still retain these names, from Sunday to Saturday. On the contrary, China culture with a long history uses numbers when calculating the number of days, whether it is a week (except Sunday) or a month, but it is unexpectedly neat in modern language! As for the concept of Zhou, it originated from western civilization. When was it introduced to China? When did it become a romantic number? These are all interesting topics of communication and interaction between civilizations in history.

Why are there seven days in a week?

From 6000 to 4000 BC, a group of Sumerians lived on the Mesopotamian plain in the Tigris and Euphrates rivers. By observing the moon's profit and loss, they found that it takes seven days from the semi-circular moon to the full moon. From the full moon to the half moon, the time is 7 days, and from the half moon to the moon, the time is 7 days; The moon disappears to the semi-circle and it is seven days. It can be seen that 7 days is the cycle of the moon's profit and loss. Therefore, they divided a month into four weeks, taking seven days as a cycle, and named these seven days with seven stars: Sun God (Sunday), Moon God (Monday), Mars God (Tuesday), Mercury God (Wednesday), Jupiter God (Thursday), Venus God (Friday) and Saturn God (Saturday). This is the most famous "week". They also built a pagoda to worship the Seven Stars, believing that the Seven Stars were on duty in turn, each in charge of one day. After Sumer, the weekly system was inherited by the ancient Babylonians.

Influenced by the civilization of the two rivers, the ancient Jews accepted the weekly system. Later, the concept of Zhou spread to Europe with Christianity from Jewish religion. Monday and Tuesday are also called "Monday" and "Tuesday" in spoken language. Sunday is called "Sunday" and a week is also called "worship".

By the way, the start time of a week is not exactly the same in different regions. Most European countries take Monday as the first day of the week. China is used to starting the week on Monday, while Japanese start on Sunday and Egyptian start on Saturday. However, international standards define a week as the first day of the week.

The seven-day week calendar has been challenged by * * * *: during the French Revolution, there was a ten-day week system, which was officially implemented for twelve years, but it was never really implemented. 1929, Stalin enforced day five in the Soviet Union, and later formulated a six-day working day, but it also ended in failure.

Why there are seven days in a week, and how is the calendar calculated?

Chinese calendar

China is one of the earliest countries that invented the calendar in the world, and the appearance of the calendar has certain influence on the economic and cultural development of China. Lunar calendar, one of the traditional calendars in China, is also called lunar calendar, lunar calendar, ancient calendar, yellow calendar, summer calendar and old calendar. Lunar calendar is a combination of lunar calendar and lunar calendar. On the one hand, the moon moves around the earth as a "moon", and the average length of the moon is equal to "the first moon", which is the same as the lunar calendar, so it is also called "lunar calendar"; On the other hand, the "leap month" is set to make the average length of each year as close as possible to the tropic year, and the 24 solar terms are set to reflect the characteristics of seasonal changes. Therefore, the lunar calendar combines the characteristics of the lunar calendar, which is also called the "lunar calendar". Today, almost all Chinese in the world, as well as countries such as the Korean Peninsula and Vietnam, still use the lunar calendar to calculate traditional festivals such as Spring Festival, Mid-Autumn Festival and Dragon Boat Festival.

The clever people of China invented the calendar and solar terms through years of hard work. According to legend, a long time ago, there was a young man named Wannian. One day, he went up the mountain to cut wood, because the sun was too hot, so he sat in the shade and rested. Suddenly, the movement of the shadow on the ground inspired him. After returning home, he spent several days and nights designing sundials. But in cloudy, rainy and foggy days, because there is no sun, the measurement will be affected. Later, the dripping spring on the cliff aroused his interest, and he began to make a five-story clepsydra. As time went on, he found that the length of the weather would repeat every 360 days.

At that time, the monarch was called Zu Ti, and the unexpected weather made him very upset. After hearing about it for ten thousand years, I couldn't help but take a sundial and a clepsydra to see the monarch and tell Zu Ti the truth about the movement of the sun and the moon. Zu Ti was very happy after hearing this, and felt very reasonable. So I left for ten thousand years and built the Sun and Moon Pavilion in front of the Temple of Heaven, as well as the sundial platform and the Leaky Pot Pavilion. Zu Ti said to Wannian, "I hope you can accurately calculate the laws of the sun and the moon, calculate the exact time in the morning and evening, and create a calendar to benefit people all over the world. 」

Winter goes and spring comes, year after year. Later, after long-term observation and careful calculation, it took 10 thousand years to calculate the accurate solar calendar. When he showed his successor the solar calendar, he was covered with silver whiskers. The monarch was deeply moved. In order to commemorate the achievements of 10 thousand years, he named the solar calendar "perpetual calendar" and named it the birthday star of the sun, moon and moon.

According to the cycle of the sun, the moon and the earth, human beings have formulated the laws of year, month, day, spring, summer, autumn and winter that conform to nature and the four seasons, thus forming a calendar. There were three calendars in ancient China: solar calendar, lunar calendar and combined calendar of yin and yang. The solar calendar is also called the solar calendar; The lunar calendar is also called lunar calendar and monthly calendar; Lunar calendar, also known as lunar calendar. Among them, the combination of yin and yang has been used to this day. Why can the lunar calendar be used today?

Today, the calendar at that time was the result of China's long-term observation of astronomical operation in order to master agricultural affairs in ancient times. The lunar calendar in China is called the lunar calendar, because it has not only the elements of the solar calendar, but also the elements of the lunar calendar. It combines the running laws of the sun and the moon and ends their influence on agriculture. Therefore, the lunar calendar in China is more practical and convenient than the pure lunar calendar or solar calendar widely used in the west. Lunar calendar is one of the representatives of China traditional culture, and its accuracy and originality are often regarded as pride by China people.

introduce

The lunar calendar used in Han areas, also known as the summer calendar, is a combination of yin and yang, with the moon as the phase and the sun as the annual cycle. The new moon, the sun and the moon rise at the same time, so the moon can't be seen on the earth, which is the beginning of every month. Depending on the phase of the moon, the length of each month may be 30th or 29th, and 12 months is a year. The solar year is divided into 24 solar terms, with odd numbers such as 1, 3, ... 23 as "knots" and odd numbers such as 2, 4, ... 24 as "qi" or "neutral qi". Because the solar annual cycle is not consistent with 12 months with the moon phase as the cycle, one month is added every four years, which is added after the month without gas. For example, in February 2004, there was only one "fright" festival, and there was no breath, so leap month would be added to February as leap February. The positions of leap months are different from year to year.

The lunar year is generally 12 months, and the number of days in a month depends on the orbit of the moon around the earth. ......

How did seven days a week come about?

I used to chat with my friends and we discussed why there are seven days in a week. A friend said that five days is good, you can go to work for three days and take two days off. Another friend said that eight days is the best, and you can take an extra day off. Of course, this is all small talk, so how did you get here seven days a week?

From 6000 BC to 4000 BC, on the Mesopotamian plain, there lived a nation-Sumerians. By observing the moon's profit and loss, they found that it takes seven days from the semi-circular moon to the full moon. From the full moon to the half moon, the time is 7 days, and from the half moon to the moon, the time is 7 days; The moon disappears to the semi-circle and it is seven days. It can be seen that 7 days is the cycle of the moon's profit and loss. Therefore, they divided a month into four weeks, taking seven days as a cycle, and named these seven days with seven stars: Sun God (Sunday), Moon God (Monday), Mars God (Tuesday), Mercury God (Wednesday), Jupiter God (Thursday), Venus God (Friday) and Saturn God (Saturday). This is the most famous "week".

After the ancient Jews accepted the weekly system, Christians spread it to Europe. Monday and Tuesday are also called "Monday" and "Tuesday" in spoken language, Sunday is called "Sunday" and a week is also called "worship".

In different regions, the start time of a week is different. Japanese people start on Sunday, Egyptians start on Saturday, and China and most European countries start a new week on Monday, which is also the first day of the week according to international standards.

At the beginning of our discussion, seven days a week was also challenged by some * * *: during the French Revolution, the official said that the system of 12 years and 10 days a week would be implemented, but it was never really implemented; 1929, Stalin forced day five and six-day working week in the Soviet Union, which also failed. It can be seen that seven days a week is deeply rooted, and * * * is impossible to change, so students just think about it.
