"7" is a magic number and a very important number. Why does humans set this number as a period of time?
Why is it not "10", not "12 ". It makes sense to set the week to 10 days or 12 days. 10 is for your fingers.
In total, 12 is the number of months in a year. Humans do not set them as the number of days of the week, which has to be recognized by ancient humans.
Data.

Since ancient humans do not understand the progressive rate system, it is very difficult to understand the numbers. Every natural number must have a pronunciation
It is obviously impossible to say that ancient humans are not very rich. Therefore, they can only recognize small natural numbers.

In ancient times, the rise and fall of the tide and the darkness of the moon were mysterious. The tide and tide go to the full moon and the moon are quite regular. Upstreaming
Tide: From the midline position to the highest position of the tide, time 7 days; from the highest position of the tide back to the midline position, time
It is also 7 days. For off-tide: From the midline position to the lowest position of the tide, time 7 days; from the lowest position of the tide rose back
The midline position. The time is also 7 days. Seven days is the time period for the tide to rise and fall.

For the moon: from the semi-circular month to the full moon, the time is 7 days; from the Round month to the semi-circular month, the time is 7 days. From the semi-circular month to the Elimination
The time is 7 days. The time is 7 days after it disappears to the semi-circular month. Seven days is also the cycle of the moon's profit and loss.

The ancients did not understand that the tide was caused by the moon, but they discovered the laws and relationships between the two. Full moon
Is synchronized, all four 7 days. Because it does not use decimal, the Ancients have not yet expressed the number of 28, so the 7
Number. Because the observation of the moon belongs to the observation of the sky, it is similar to the observation of the beginning of the day, the stars, so it is called the week, the period is the cycle
. The Chinese pronunciation of 7 is the same as that of START, go, period, and Qu, indicating the round-trip meaning, that is, the cycle. 7 is in the sky
The cycle between the moon and the tide, which corresponds to the number of days, and 10 corresponds only to the finger, not the sky, not the ancient
People understand and accept it. 12 is not a cycle, and there is a large ending number behind 12. In addition, 12 is over 10.
Before the progressive rate system, ancient humans could not express themselves. Respondent: Guan Yan Kang-12-13

Where can I find it? Oh, dizzy. So many. Respondents: Lotte Xuan-assistant level 2 10-13 According to Jewish, Catholic, and Christian beliefs, it took six days for God to create everything and rested on the seventh day. As a result, the believers work for six days and take a day off. This is the source of seven days a week. Respondent: Hu Junyuan-trainee magician Level 2 10-13 Yes. God means: pay1181350-assistant level 2 10-13. 7 days, so 7 days: hsh110-assistant level 3 10-14 In my opinion, we should first invent a seven-day week timer, and then come up with the so-called god to explain.
In ancient times, there were seven familiar celestial bodies: Venus, Jupiter, mercury, Mars, Saturn, (this is the five lines that everyone is familiar with) the sun and the moon. These seven things are called the Seven week in China. Of course we didn't use the week timing method, but these seven celestial beings are also very familiar, so they just took seven days as a week. Respondent: qiuzhai-Xiucai Level 2 10-17
