The Science
Planetary movement comes in two parts: earth rotation on its axis and solar orbit around the sun.  The earth rotates on its axis and we get day time and night time.  The earth rotation on its axis plus the movement around the sun, the solar orbit, gives us our four seasons.  When the seasons repeat, we call that a year.
So, if we start counting the earth moving round and round in space, we end up with days and years.  Two days is two earth rotations on its axis and so on. It takes the earth 365 rotations on the axis …
