Hump Day

Posted by TM on July 04, 2001

Does anyone know when Hump Day phrase began?

Around 1996 I was talking with a sales rep from a Dental company. It was Weds. I told him I call weds "Hump Day." He said,"Why is that?" Because tues is just another Monday, Thurs is so close to Friday it's just another Friday, but once the workday is done on Weds, you're over the hump. Now I'm hearing it everywhere ... especially on radio stations.

When I mentioned this to my brother-in-law this evening, he fairly much said I was full of crap, that the phrase "hump day" to describe Weds has been around since the 40's.
Can anyone shed any light on this?
