Have you ever stopped to consider why we have seven days in a week. Why a 7 day week? I would like for you to take just a few minutes, now, and look into the reason for using a seven day week.
Is there an astronomical reason?
Can we look at how the earth is situated in Solar System to discover a reason for using seven days to form a week? Let us see. As far as the Earth’s orbit around the sun, it takes 365 1/4 days for the Earth to make one complete trip around the sun. That does not divide by seven very well at all. So, we surmise that the orbit of the Earth around the sun is not the determining factor or even a contributing factor as to why we exercise a seven day week
In relation to the moon we find that the moon comes very close to showing us a number that divides by seven. It orbits the Earth every 27.32 days. It comes pretty close to defining a four week period if seven days form a week. But there is no definitive proof that this was ever the consideration for a seven day week. If it had been, the computations for lunar location would be totally incomprehensible within a few hundred years. Though intriguing, the moon does not give us a good reason for establishing a seven day week.
As we look at the other bodies in the Solar System we are not able to see any rhyme or reason to decipher a seven day segment in their motions that would influence us to establish a seven day week.
There are some who by studying past civilizations and how they viewed the night sky have taken the view that the moving lights in the night sky, (those which changed position over the period of the month or year) were what determined the number of days in the week. But as knowledge of the night sky increased it should have changed their understanding. So, even the “gods” of the night sky did not influence the number of days we determine a week
There have been many cultures and civilizations that have fostered the idea of seven as being a holy number. The Egyptian pyramid was built of 4 triangles(3) and thus 4+3=7. In the Aztec and Mayan pyramids built in Mexico there were seven steps in the layers of the structure. The Jewish religion holds that the number for perfection is seven. One can find instances of the number seven and its importance in almost every civilization, no matter how advanced or not advanced.
However, that is not a good answer for why seven days should be established as a week.
Other possibilities of a week
There have been attempts to use a different number to determine the days of the week. They have ranged from three days a week to as many as nineteen days a week. Two of the most notable were: the French revolution where they instituted a 10 day week. This was done in an attempt to divorce France from anything associated with Christianity: the other was done in Communist Russia in the 1920s. Suffice it to say that neither experiment worked. In fact, they were total failures.
No experiment in changing the days of the week have brought success.
Recent scientific studies have shown that in addition to the circadian clocks that human bodies and all living things have as well as monthly and yearly clocks, there is a weekly clock which operates on a seven day cycle. It was found that blood pressure cycle, immune response to infections, hormone cycles, blood production and urine chemicals, and heartbeat operate on seven day cycles. It is no wonder that when societies have sought to change the cycle of work and rest that their production dropped dramatically to the point that the experiment had to be abandoned.
Why then, seven days in a week?
If one wishes to be honest and scientific in his approach, one must not discount any possible reason. For the humanistic-materialistic “scientist” who will not allow “a divine foot in the door”, he or she will have to invent all kinds of “could have”, “maybe”, or “perhaps” scenarios which may or may not have been possible. But, proof will come in how it lines up with the facts. Science has found a seven day clock in biology, just as it found the circadian(daily) clock. It is supported by empirical data. So, where did the seven day week come from?
The seven day week came from the God of creation. Why a 7 day week? Because the Creator made it so. He has revealed His handiwork in His creation. It says this in Romans 1:20ff: “For since the creation of the world His invisible attributes are clearly seen, being understood by the things that are made, even His eternal power and Godhead, so that they are without excuse, because although they knew God, they did not glorify Him as God, nor were thankful, but became futile in their thoughts, and their foolish hearts were darkened.” People who do not wish to honor their Creator may reject this fact but they must close their eyes and minds to the truth to do so, and many do
It is noteworthy that when Jesus commented on the Sabbath, “The Sabbath was made for man..” in Mark 2, He was quoting Leviticus 23:3 which says, “Six days shall work be done, but the seventh day is a Sabbath of solemn rest.” God, The Creator defined the week for man. Six days of work and then a day of rest unto the Lord. When walking in obedience, work is not a curse, it is a blessing. But it is not the end product. The end product is a Sabbath of solemn rest unto the Lord.
Though we have been fearfully and wonderfully made we are not created and formed for just work or just rest. We have been created to have fellowship with our creator. In Hebrews 4:9 it says this: “There remains therefore a rest for the people of God. For he who has entered His(God’s) rest has himself also ceased from his works as God did from His.”
God’s picture in the 7 day week is to point you to the rest that He has for you in Christ Jesus. His desire for you is that you relax and quit trying. Cease from working to please Him. Let Him work in you. In Philippians 2:13 it says this: “for it is God who works in you both to will and to do for His good pleasure.” Let Him do the work.
The reason for 7 day week
“Why a 7 day week?” you may ask. The reason is that your Creator loves you more than you can ever know and the 7 day week is only one of the many ways that He manifests that love for you. But, the greatest manifestation of that love for you was expressed when He sent His only begotten Son to suffer and die on a cruel cross so that you might be able to spend eternity with Him. But He loves you so much, that He will not over rule your free will and make you accept that gift of grace. The choice is yours. No one but you can make that choice.
May you be overflowed with God’s grace and give in to that eternal love. I encourage you, “Receive Jesus, today!”
