@Graci I took some classes at Emory U. "back in the day" and they had something they call Wonderful Wednesday. (I read it was discontinued some time back, to the chagrin of many.)
Classes were Monday Thursday or Tuesday Friday. There were no Wednesday classes at all. It broke up the monotony of the week just enough to take a breath.
It's a lot easier to go back to work when there is just one more day for a break. I think it was much better than getting three day weekends.
