Whats a week?

So, I guess weeks go away when days go away. Its 414 in the AM on Friday, but I think I started this day on thursday, but am not really sure because wednesday sorta went into overtime and became thusday, but then I did get to sleep some before real thursday, but now is it still thursday? I just dont know. Perhaps if I go home and go to sleep, when I wake up it will really be friday. BUT I think that leagally it IS friday now...

I am very confused right now. But I know that my pathetic grip on anatomy goes to shit at 3 AM.
