Monday's child is fair of face

Tuesday's child is full of grace

Wednesday's child is full of woe

Thursday's child has far to go

Friday's child is loving and giving

Saturday's child works for its living

And the child that's born on the Sabbath day

Is fair and wise and good and gay
—Traditional Nursery Rhyme

Good day, Monday? Feeling gay, Tuesday? It's okay, Wednesday.

Okay, let's play: What is, you say, a good way, to this day, to give away a Meaningful Name? A weekday!

This is useful because each weekday has an array of meanings. Many European languages derive their names from the Roman practice of naming them after the Roman gods, either by adopting the Roman names or by substituting them with similar local gods (e.g. Germanic gods). From the original Latin, we have Monday as "Dies Lunae", Moon's day, Tuesday is "Dies Martis", Mars' day, Wednesday is "Dies Mercuri", Mercury's day, Thursday is "Dies Iovis", Jupiter's day, Friday is "Dies Veneris", Venus' day, Saturday is "Dies Saturni", Saturn's day, and Sunday, "Dies Solis", which is...sun day.

This is easier to remember in Latinate languages. The days of the week in French, for example, are Lundi, Mardi, Mercredi, Jeudi, Vendredi, Samedi and Dimanche.

From the Germanic languages, we have Sunday as The Sun's day (Sunna), Monday as Moon day (Máni), Tuesday as Týr's day, Wednesday as Wotan's/Óðin's day, Thursday as Þór's day, and Friday as Freyja's day; in English, Saturday is unique in having a Latin-derived name, elsewhere it is bathing or pool day (Laugardagr). Hooray!

This pagan-based naming has ticked off the Catholic Church, so some countries with lots of Catholic influence will have boring names, based on what prayers should be done. Or even more mind-numbingly uninventive: in Iceland an ancient catholic single-bishop decision renamed Tuesday to "third day", Wednesday to "middle week day", Thursday to "fifth day" and Friday to "fasting day." The Quakers also used numbers for days of the week instead of honoring Pagan deities (Sunday was the first day, etc).

So, anyway, naming a character in this way is a good way to connect him to some of these previously described figures. Also, naming a character after a weekday may imply he is similar to the day's feel (See Seinfeld). Someone named Monday can't be fun, because Garfield hates Mondays, right? On the other hand, Saturday must be super fun to hang out with, and, ladies, he's single.

Another way is getting away with naming a character after a month. This is not as meaningful because some people actually do name their kids after months (April, May, June), and, not only that, two of our favorite months were actually named after Roman emperors with considerably large egos (July and August, for Julius and Augustus).

Examples of Day of the Week Name include:

Anime & Manga

  • Friday Monday from Madlax.
  • In the Alabasta arc of One Piece, the Baroque Works organization gives days of the week as Code Names to its high-ranking female agents. (The very top female agents above them get codenamed after specific holidays.) Like many other names in One Piece, there doesn't seem to be any significance besides sounding cool.
  • In Bishoujo Senshi Sailor Moon, the Inners all have last names that contain the kanji used for the days of the week: Usagi Tsukino (tsuki = moon = Monday), Ami Mizuno (mizu = water = Wednesday), Rei Hino (hi = fire = Tuesday), Makoto Kino (ki = tree = Thursday), Minako Aino (ai = gold = Friday). Sailor Saturn uses the kanji for earth (to) for Saturday.
  • In Digimon Xros Wars, the epithets of the Death Generals each start with a kanji that corresponds to a day of the week. The first four appear out of chronological sequence (fire, moon, wood, water), but the last three are in order (gold, earth, sun).
  • In Kuroko no Basuke, each of the main members of the Seirin High Basketball Club (except for Kuroko), have a kanji corresponding to a day of the week in their name. In order starting from Sunday: Hyuuga(日), Izuki(月), Kagami(火), Mitobe(水), Kiyoshi(木), Koganei(金), and Tsuchida(土).

  • One of Alan Moore's one-shot strips for 2000 AD titled "Chronocops" which was modeled as a parody of Dragnet with Time Travel, saw a main character named Joe Saturday with a partner Ed Thursday. A detective from the Fraud Division is named Marv Wednesday, and Ed's grandmother has the name Tuesday.
  • Legion of Super-Heroes member Mon-El (real name Lar Gand) was named that way because Superboy mistook him for his older brother (Lar had amnesia at the time) and they met on a monday. (-El being Superboy's family surname.)

  • In The Time Travelers Wife, Gomez mentions that he and Charisse were going to name their daughter Wednesday, but change their mind.
  • The Man Who Was Thursday by G. K. Chesterton, though there the days of the week are just the code names for the seven leaders of a secret anarchist society and not their actual names. Rather than gods or nursery rhymes, the names are symbolic of the (slightly adjusted) Creation Week.
  • Mr. Wednesday from American Gods. The name is actually Foreshadowing that he is actually Odin (Odid>Woden>Weden's-day).
    • He even acknowledges it when he first gives his name as Wednesday, claiming that "Today is my day." This is almost a spoiler for anyone who already knows the origin of the day's name, and can thus work out his identity right away.

  • Wednesday Shadowmist, the heroine of Iron Sunrise by Charles Stross.
  • Mr. Monday from Stardust, whose name ends up playing a role in the No Man of Woman Born ending.
  • The eponymous heroine of Friday by Robert A. Heinlein.

  • The trustees in Garth Nix's Keys to the Kingdom series are Mister Monday, Grim Tuesday, Drowned Wednesday, Sir Thursday, Lady Friday, Superior Saturday, and Lord Sunday.

  • In Blue Avenger Cracks the Code, the sequel to The Adventures of Blue Avenger, one of Blue's childhood friends is named Tuesday.
  • In the teen novel Adorable Sunday, the protagonist explains that when she was born, her mother got the idea in her head that she should be called Sunday, on the grounds that she would grow up to be "somebody." (The plot focused on her brief career in modeling.)

 Sunday's dad: Besides, she was born today, and today is Thursday.

Sunday's mom: I don't care. Sunday is a special day, and this is a special child. I can't help when she was born.

  • The children's picture book Heckedy-Peg by Audrey and Don Wood features seven children named after the days of the week (the oldest is Monday, the youngest is little Sunday). Also notable for gorgeous illustrations and a dose of Nightmare Fuel (the wicked witch turns the children into food and will eat them unless their mother can guess which food is which child).
  • Brian Doyle's novel Spud Sweetgrass has a character named Mr. Friday, who, appropriately enough, runs a chain of chipwagons.
  • Welkin Weasels: Gaslight Geezers shows Spindrick Sylver's anarchist group naming themselves after days of the week, which leads to an entertaining Who's on First? routine when he tries to ask "Saturday" for help and everyone assumes he's making an appointment for the next meeting.
  • Guy Montag in Ray Bradbury's Fahrenheit 451 (his surname is German for Monday).

  • The young adult novel The Snowbird features a character named July, who explains that he had so many older brothers and sisters that his mother was completely out of ideas as to what to name him, so his father told her to just name him after the month in which he was born. Humorously, he adds, "Good thing I wasn't born in April."
  • A short story in the Hellboy book Oddest Jobs discusses this. Hellboy, Liz, and another B.P.R.D. worker try to think of someone named Thursday, and Hellboy ends up telling a story of a man with the last name Thursday. The man comes from a race of Thursday Men, who are trying to prevent the sinister and destructive Wednesday Men from coming through to our dimension.
  • The hamlet folk in the book of Lark Rise to Candleford nicknamed their farmer, Morris, "Old Monday". This got transferred to the TV series without the man's real name being mentioned.

  • There was a Square One TV sketch that was a parody of The Addams Family, called The Adding Family. In it, the two (unseen) children were hit with a terrible (from their perspective... and maybe a little bit of ours, too) curse. One was Pugster; the other was Thursday.
