This is due to their proximity to Polaris, the North Star. Circumpolar stars rotate counterclockwise around the North Star. Polaris is the only star that is always in the same spot. In a month the stars rise and set two hours earlier. Over the course of a year this amounts to 24 hours.
All stars are in the same positions at the same date and time each year .
Each hour the stars move 15 degrees across the sky . If you stay up all night, you can see just about all of the stars that can be seen from your latitude. The only ones you would not see are those close in the sky where to the sun is. The stars are there during the daytime but we cannot see them because of the light of the sun . The stars you can see change with your latitude .
