We’ve been measuring time for as far as we can remember, and maybe a minute longer. Everything turns and spins around time as well (and money.) We also know that time per se does not really exist and is a man maid thing to measure, well something. And with any of those things that we came up with, we found a way to complicate it a bit and make it so for a long time now so that we also got used to how it usually works without being too specific. Some people know how to grasp the concept more than others, since a minute for someone is a whole other story open to interpretation for someone else.
The following video is more of a scientific approach on explaining these simple things, such as light years, a second and a whale hour. When put into perspective, some things are really quite closer than thought at first. Have fun!
