When you have an assignment worth 100% of your grade due the Tuesday after Spring Break, your day goes by pretty damn fast. Lol
Also, days go by faster as you age, since your perception of the time also correlates to how long you have lived. Your age is a measuring bar--when you're 5, 5 years is like a lifetime away to you, because it is literally. When you're 20, 5 years is 1/4th your life time and therefore feels comparatively shorter to you. Pretty sure this was verified by psych studies.
