In reality, people's moods do not change dramatically over the course of the week, and people are not vastly happier on Friday evenings and Saturday mornings than they are on Mondays.
"'Stereotypes like 'Monday morning blues' and 'TGIF -- Thank God It's Friday' are largely inaccurate theories of how moods vary'" day by day, University of Sydney marketing professor Charles Areni noted in a paper published in the current issue of the Journal of Applied Social Psychology. "In short, Mondays are not actually blue, but people persist in the belief that they are."
