It's an old saying. Back in old days, they didn't have smog or other stuff that made the air dirty. So, in the daytime the air was clear and you could see a long distance. So, "clear as day" means that the facts are very clear. You can clearly see all of the evidence.
A day that which is cloudless, clear and pleasant.
If you clear the market, it means that you have finished selling for the day and you pack everything away. Or it could mean you are trying to sell out all of the products you've got.
