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.
- In G.I. Joe: A Real American Hero (Marvel), Snake Eyes hates Tuesdays.

- Garfield famously hates Mondays.
- 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. For example, Garfield wakes up on a "beautiful Monday morning" with clear skies and no rain in sight — except over his house, resulting in him getting rained on.
- He also hates February — 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.
- He especially hates Monday the 13th. Especially if that Monday the 13th falls on a February.
- Jim Davis, his creator, later explained that, while Garfield doesn't work or study, Mondays are a reminder to him "that his life is the same old, same old cycling again". Thus, he hates them, and the universe uses Mondays to deliver some Laser-Guided Karma.

- In Mutts, there's a strip where Sourpuss says he hates Mondays. Then it rains, leading him to say that Mondays hate him, too. Also a Running Gag.

- In the spy parody film OSS 117: Lost in Rio, Agent OSS 117 goes to the French secret service offices on a Monday morning, asks one secretary how she's doing, and she answers with a jaded "Like on a Monday...".

- Adrian Mole: Adrian moans about Sundays more than other days, because of shops being closed, occasionally being made to go to church by his grandmother, his parents doing nothing but read the Sunday papers, or there being no postal delivery.
Does the clergy imagine that God gives a toss whether or not humans receive letters on a Sunday?

- One of the speeches on Doctor Who that the Eleventh Doctor names several days as not very interesting. It also reveals he really like Saturdays, perhaps because a certain British sci-fi show airs on that day?
The Doctor: Time isn't a straight line. It's all... bumpy-wumpy. There's loads of boring stuff. Like Sundays and Tuesdays and Thursday afternoons. But now and then there are Saturdays. Big temporal tipping points when anything's possible.
- The Doctor would later change their tune on Sundays once the series started airing on Sundays as of 2018.
- Drake & Josh: When Mindy was promoted to assistant manager at the movie theater, she makes Crazy Steve works on a Monday. Helen and Josh freak out, because Monday is his "bad day". Steve goes on a rampage until Josh is able to calm him down.

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

- Retail workers usually hate Saturday and Sunday in particular:
- In general, due to the increased activity and thus volume of stressful customer interactions as a result of people with traditional Monday-Friday jobs being off on those days and thus getting the chance to get shopping done. For people working in such industries, Monday is perhaps one of the least stressful days of the week to work.
