 That is why the first version of the Ten Commandments, the version in the book of Exodus, ends with these words, For in six days God made the heavens and the earth, the sea, and all that is in them. But he rested on the seventh day. Therefore God blessed the Sabbath day and made it holy. However you interpret six days, and many Jewish and Christian believers do not translate days as 24-hour periods, the point is this.
