The Starfinder is a version of an ancient model of the sky. These models are called planispheres. The word "planisphere" means "flat sphere" - the apparent dome of the sky flattened into a sheet. Devices like this were used in ancient Rome as early as 27 B.C.
A Starfinder will show you how the sky looks at any hour of any night of the year. All you have to do is "program" the Starfinder with the date and time you want. The Starfinder can also tell you when a certain constellation will be visible.
