Understanding what is in the sky and what's around it is a fun skill to have, you can always tell which direction is what, the time of year (in case you forgot) and the time of night, assuming you are looking outside frequently enough to notice the change. You can even tell how much time has past if you are in the same spot and have a point of reference (like in a hot tub facing a tall tree) using your hand to measure. You can use Stellarium on your computer or phone to help see what's up there as well as a planisphere to know exactly what is up today at your lattitude and where it is at what hour.
