Psa 90:4 For a thousand years in thy sight are but as yesterday when it is past, and as a watch in the night.
Those trying to fit evolution into the creation story, try to say that the creation was in thousand year days. I do not see it that way from the Bible.
Gen 1:5 And God called the light Day, and the darkness he called Night. And the evening and the morning were the first day.
A day is defined as evening until morning. The next day begins at the evening. Adam named his wife Eve, because she was the beginning. Evening is the beginning of a day in the Bible account. The Sabbath is from sundown Friday to sundown Saturday. The Sabbath is the seventh day as described by the hand of God in the ten commandments written in stone; it is a day of rest.
Exo 23:12 Six days thou shalt do thy work, and on the seventh day thou shalt rest: that thine ox and thine ass may rest, and the son of thy handmaid, and the stranger, may be refreshed.
