Navbar dropdown doesn't work

I'm back! (hours later, lol)

This time I have a dropdown in my navbar that doesn't work. I've been on a bootstrap spree today and was trying to create a dropdown in my navbar that shows the various days. I went back and dissected the code to see if maybe I took something out that should've stayed in but nothing jumps out (to my knowledge).

Thanks in advance to those who give feedback! :)
