Mondays are bad but for some reason Tuesdays are the worse for me. Meetings and conference calls at work chop up my Tuesday and I never feel like I get anything done. Wednesday are my catch up day. I don't usually have meetings or conference calls and I can focus on what I didn't get done on Tuesdays. Thursdays and Fridays are "clean up" days. Days where I can get all the bits and pieces put together and completed.
What day is your "I wish this day was over" day? Which day is your "Whew! I'm half way there!" day?
