Were the seven days of creation in Genesis seven twenty four hour periods? - Some conclusions

Last week we looked at the significance of the structure of the Genesis creation account and its association with the Sabbath and a seven day week.
The seven day week amongst Israelites was rather unique considering they were leaving Egypt which had a 10 day week. This was another means of getting Egyptian traditions, gods, fleshpots, etc. out of the soon to be formed Israelite nation.

400 years in Egypt had substantially affected their culture, identity and religion.

Another purpose of the Creation account was to establish the Creator’s ascendancy over the previous gods they had encountered and would encounter. Instead of a gods of the sun, moon, water, etc.
The God of Abraham Isaac and Jacob was instead the Creator of all these things.

Then as a defining covenant a seven day week was given to the Israelites with its Sabbath to set them apart from all surrounding nations.
In ancient times weeks of all different lengths existed.
An eight-day week was used in Ancient Rome and possibly in the pre-Christian Celtic calendar. Traces of a nine-day week are found in Baltic languages and in Welsh. The ancient Chinese calendar had a ten-day week, as did the ancient Egyptian calendar.

A six-day week is found in the Akan Calendar. Several cultures used a five-day week, including the 10th century Icelandic calendar, the Javanese calendar, and the traditional cycle of market days in Korea. The Igbo have a "market week" of four days. Evidence of a "three-day week" has been derived from the names of the days of the week in Guipuscoan Basque.

More recently and once again likely in an effort to create a national difference and establish a break from the past:
Between 1929 and 1931, the USSR changed from the seven-day week to a five-day week.
In 1931, after its brief experiment with a five-day week, the Soviet Union changed to a six-day week.
The calendar was abandoned 26 June 1940 and the seven-day week reintroduced the next day.

Globally we have eventually gravitated towards and settled on the 7 day week because it is astronomically and therefore calandarically superior.
The discussion of the astronomical significance of a 7 day week is a complex topic and best left to its own post.

Now let’s delve a little deeper into the other books of Moses to see if the literary structure that seems so apparent is utilized elsewhere.
Right off the bat we notice that Moses’s life is broken up into 3 periods of 40 years:

In Egypt being raised as a prince of Egypt
In Midian receiving his spiritual training and preparation for his mission
Leading Israel in their sojourn in the wilderness.
The account of the plagues of Egypt in Exodus.

There were ten plagues of Egypt.

We see that they are divided into a very similar literary structure as with the creation account, except this time there are three groupings of three and one final one that once again breaks that pattern for emphasis.
