“Hump Day” is a day that gets people “over the hump” (over 50% completion of something). The “hump day” of the seven-day week is Wednesday. The term “hump day” has been cited in print since the 1950s. “Hump day” now almost exclusively means Wednesday, but the earliest uses in 1955 and in 1956 had other meanings.
“Hump Day” has been printed on many images, usually featuring a camel.
