Tuesday is the worst day of the week, let's go through
Saturday is the best, because it's pretty much total freedom. Normal shit is open for normal hours, you can start as early or as late as you want, it's a blast
Sunday is basically just Saturday part 2, continue to enjoy your weekend, eat something nice, rest, enjoy your (admittedly waning) time off.
Monday you get to regale your coworkers with tales of what you got into over the weekend, and if you like the people you work with, you get to see your friends some more.
Wednesday's already the middle of the week, so you're already thinking about the weekend. You can also use 'hump day' as an excuse to get some, in some cases (YMMV).
Thursday means you're just a little closer to Friday, and you're already able to start thinking about doing a friday lunch with mates, get some of those two-day shipping orders in so you can do fun stuff over the weekend, etc.
Friday's got peak excitement for preparing for the weekend
tuesday (which I refuse to capitalize because fuck you tuesday) can eat a fat bowl of soggy partially-limp dicks, the afterglow of the weekend is over and you're about as far from the weekend as you can possibly be. Fuck you tuesday, you fucking stupid day. Nothing good seems to happen on a tuesday.
