"Day of the Week" Name

Go To
"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 hard for a living
And the child that's born on the Sabbath day
Is fair and wise and good and gay"
— Traditional Nursery Rhyme

In many traditions a handy shortcut to giving a child a Meaningful Name has been to name that child after one of the days of the week.

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 replacing 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 Mercurii", 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. In Spanish, those days are lunes, martes, miércoles, jueves, viernes, sábado and domingo. An exception but still easy is Portuguese, where considering domingo is the first day, the five following it before sabado are [ordinal number]-feira starting with second (Segunda, Terçanote , Quarta, Quinta, Sexta).

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 names based on what prayers should be done. Or even more uninventive: long ago in Iceland, a Catholic bishop 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), and in Hebrew they've always been numbers ("Sabbath" comes from the Hebrew word for seven).

Naming a character in this way is a good way to connect them to some of these previously described figures or imply they are 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, we still use two month names originated by Roman emperors with considerably large egos (July and August, for Julius and Augustus).

    Anime & Manga 
  • Friday Monday from Madlax. Given that he is the creepy, irredeemably evil, Malevolent Masked Man Big Bad, his normal name serves as quite the contrast.
  • 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, while the vice-president gets the codename "Miss All Sunday", which is supposed to represent all the Sundays of the year.) Like many other names in One Piece, there doesn't seem to be any significance besides sounding cool.
  • In Digimon Fusion, 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's Basketball, 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).
  • The Italian adaptation of Yattodetaman, called Calendar Men, had a field day with this. Since the series' main theme is time travel, they decided to give everyone names related to days of the week, months and so on. For example, Mirenjo became Lunedì (Monday) and her little brother Komaro became Sabato (Saturday); her two lackeys were renamed Settembre and Ottobre, full names Primo Settembre and Due Ottobre ("September the First" and "October the Second"), the hero's wimpy alter ego Wataru Toki became Beppe Domani (something like "Joe Tomorrow")...
  • In the Grimm's Fairy Tale Classics Snow White episodes the Dwarfs are named after the days of the week.
  • Tuesday Simmons is one of the titular characters of Carole & Tuesday.

  • Upin & Ipin: Tok Dalang's real name is "Senin bin Kamis", which literally means "Monday, son of Thursday".

    Comic Books

  • 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.)
  • Sort of applies to DC Comics villain Solomon Grundy, who was (re)born on a Monday (and thus named after the famous nursery rhyme.)

  • 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.
  • Mr. Wednesday from American Gods. The name is actually foreshadowing that he is actually Odin (Odin>Woden>Weden's-day). In other words, it's an Inverted Trope: The day is named after him. He even acknowledges it when he first gives his name as Wednesday, claiming that "Today is my day." though he notes that because of the stormy weather, "it might as well be Thursday" (Thor>Thur's-day) This almost spoils his identity for anyone who already knows the origin of the days' names.
  • Sharon Creech's Bloomability stars a protagonist named Domenica Santolina Doone, or "Dinnie" for short. "Domenica" is Italian for "Sunday," her mother naming her such because she was born on a Sunday and that made her blessed. She certainly gets a lot of opportunities.

  • 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. This was actually the very first thing that Garth Nix thought of, leading into everything else. The names just kind of fell into his head.
  • 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, with the most mysterious bordering on God-like of the bunch naturally being Sunday.
  • The protagonists of the children's book A New Day by Brad Meltzer are colorful personifications of the days of the week. One of them, Sunday, quits being a day, forcing the other days to seek a replacement for her.

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 Thursday Next books, of course. The eponymous heroine aside, her mother is Wednesday Next, her son is Friday Next, and her daughter is Tuesday Next. The one who doesn't fit is her daughter Jenny. This foreshadows the fact that Jenny doesn't exist—she's a mindworm (an imaginary, persistent idea) implanted in Thursday that later spreads to the rest of the family, making her a Double Subversion.
  • In The Time Traveler's Wife, Gomez mentions that he and Charisse were going to name their daughter Wednesday, but change their mind.

  • 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.

    Shadow: Wednesday.
    Wednesday: [sing-song voice] Then I guess it's my day...
