Researchers at Stony Brook University have examined the effects of various weekdays on people's moods in a large-scale study, finding that the concept of "TGIF" had a positive effect on people's moods while the idea of "Blue Monday" didn't hold water when compared to its effects on people's moods on other weekdays.
Gawker.com phrased the study's findings this way: "people hate Mondays just as much as they hate Tuesdays, Wednesdays, and Thursdays."
"Despite our global beliefs about lousy Mondays, we conclude that this belief should be abandoned," Professor Arthur Stone, one of the study's authors, told Gawker. "Cultural myths may vastly over-emphasize actual day of the week mood patterns."
