The French revolutionaries of 1789, had ten days in the week. This did not last long because working people were exhausted before end of the ten day week. Eventually sanity prevailed and the week reverted to seven days, just as had been instituted in the Pentateuch of the Holy Bible, making Sunday, the first day of the week, the day of rest on which everyone was prohibited from doing servile work, giving time for the worship of God.
As the angular rotation speed of the Earth becomes less, astronomers can decide what to do about this situation. There will only be a significant noticeable slowing down of the Earth’s rotation several million years after the year 2020. At that time there will probably be an artificial seven day week consisting of twenty-four hour in each day as at present while the Earth might take fifty or more hours to complete a rotation. That is Sunrise will be every twenty-five hours.
Answer:
It had no days because it did not exist. Not even retroactively and hypothetically as did A.D. 1, which was given that number half a millennium later.
The concept of “zero” (being introduced in more-or-less the form we know it in by Arab mathematicians of the Middle Ages) was not really part of the ancient Roman math that would have been used by the church historians who came up with the concept of “A.D.” (annum Domini) several centuries later.
Even had they been familiar with the concept of zero, it’s unlikely that they would have used it. A.D. 1 was an ordinal, the first of something, specifically of the life of Jesus, though it’s the consensus of religious scholars nowadays that Dionysus Exiguus (“Dennis the Short”) was actually off by a couple of years when he made his calculations in 525 A.D.¹
Years from before A.D. 1 were designated as “B.C.” by the Venerable Bede a couple of centuries after Dennis. Bede, too, considered the years to begin at “1”, although he counted backward, leaving no “year zero” in the middle.
