Characters can sometimes hate a certain day of the week, due to bad luck and misfortune that seem to only happen to them on that day. When they start hating it, they often start dreading the coming day on the day before.
As suggested by the trope name, Monday is one of, if not the most hated-on days, perhaps because it's the day that many people go back to work/school after the weekend, which not many people look forward to the ending of. Of course, this isn't universal, as some people work in facilities that have a different weekly business schedule (such as Wednesday through Sunday), or are open 7 days a week and therefore the days one has off may be different than the usual Saturday and Sunday, or even inconsistent from week to week.

- Originally, there was no real reason for this, since he's a cat who doesn't have to go to school or work, but later strips would make him a Cosmic Plaything on Mondays specifically.

- He also hates February specifically — he refers to it as the Monday of months. Much like how Monday is listed as the second day of the week on most calendars, February is the second month of the year in the Gregorian dating system.

Before I know it, Saturday's gone
But it's Sunday now and you can bet that I'm all right
