Looking at the phone calendar today, I found a question, why does the week start with Sunday in front of it, not Monday?
So, my sister went to search for it with questions. It is said that the ancient Babylonians divided the 28 days into four equal parts according to the lack of the moon, every seven days and a week, and each day of the seven days was named after the seven stars in the universe, named "Seven Yao", named "Seven Yao". Ancient Jews and certain peoples in the East also used the "seven days" to record the day, so that the seven days of the day began repeatedly, so it was also called the week. In the first century BC , the Roman calendar had this notation , but it was for astrological purposes only. By 231 AD, Constantine the Great was officially announced on March 7, and it was customized and has been used ever since. Which day of the week begins? According to the ancient seven stars, the day is the largest, so the "seven days" of the sun is the beginning of the week, the rest of the moon, fire, water, wood, gold in order for Monday, two, three, four, five, the earth day is Saturday, is the end of the week.
But in reality, the start time of the week is not exactly the same in different regions. The Cambridge International English Dictionary interprets week as follows: a period of seven days either, from the beginning of Sunday to the end of Saturday, or from the beginning of Monday to the end of Sunday, i.e. a 7-day period from Sunday to Saturday, or from Monday to Sunday. If this interpretation is followed, then the first day of the week can be either "Sunday" or "Monday". For example, the Egyptian week begins with Tuyao Day (Saturday), many English-speaking countries, Judaism, and Japan start with Sunday, while Islam ranks Jinyao Day (Friday) in the first place, most European countries take Monday as the first day of the week, and our mainland customs to think that Monday is the beginning of the week.
There is another theory about seven days for a week, which is purple: it is derived from the biblical book of Genesis, which records that God created all things in the world and shared six days: God created light and separated light and darkness, and God called light day and darkness night. There were evenings, there were mornings, and it was the first day. God said that there should be air between the waters, dividing the water into upper and lower levels, and God created heaven and earth,...... There was night, there was morning, the second day, and God said, "The waters of the world will gather in one place, so that the dry land will be exposed, and God will call the drought the land, and the gathering place of the water will be the sea... God also made the earth grow grass and seeds and vegetables,...... There was evening, there was morning, it was the third day.... The work of God's creation is finished, there is night, there is morning, this is the sixth day.... By the seventh day, The work of God's creation was finished, and on the seventh day all his work was rested and rested. God blessed the seventh day, which was made holy. The Jews first observed the Sabbath and used the sunset as the beginning of the day.
There are really many opinions, so which day will prevail?
Authoritative statement: The International Organization for Standardization's international standard ISO 8601 "Data Storage and Exchange Forms, Information Exchange, Date and Time Representation Methods" stipulates the method of representation of dates and times, which clearly states that each calendar week starts on Monday and Sunday is the 7th day.
The standards adopted in our country are the same as the international standards, that is to say, Monday is a week to start in the country is a convention, and it has become our norm to be nervous and busy on Monday. After a busy week, tomorrow is Saturday, the day after tomorrow is Sunday, think about it and be happy, right?
