Title by Number

Looking for a good name for your work of fiction? Look no further, just find a number tangentially related to the premise and use that as the title. Supposedly, this makes it sound "mysterious," especially if the number is also used as an Arc Number.

Compare Running Time in the Title.

Note: There are two groups on this page - first are titles with numbers; then below that, titles with years.

Examples with Numbers:

Anime and Manga

Black Jack 21.
Eyeshield 21.
5 Centimeters Per Second
Eureka Seven. Eureka is the name of the female lead. "Seven" is never talked about.
Macross II
Macross 7

- Thr3e, based off the book by Ted Dekker.
8 1/2, so called by director Federico Fellini because he had previously directed six features, two shorts, and one film with a co-director—counting the shorts and the collaborative works as half-pictures, that made this one number eight and a half.
- This was loosely adapted into a musical called Nine.
- Just to add further confusion, the 3D animated (and unrelated) movie 9 is coming out the same year, an adaptation of the short film of the same name. The way to distinguish them is how they're written: word (Nine) or digit (9), but plenty of sites ignore that and confuse the issue even more.
- It's worth noting that District 9 came out that year as well, and was playing in cinemas alongside 9 (the one with stitchpunks).
The Number 23.
3, a Biopic of NASCAR driver Dale Earnhardt Sr., who used the number for most of his career. The same number can be seen on numerous cars and pickup trucks in the Southern U.S.
61* attached to Roger Maris; nothing to do with his own number (for most of his career, 9), but it's the number most associated with him (for his breaking of Babe Ruth's 60-homers-a-season record, the asterisk being added because seasons were shorter in Ruth's day).
- Also for the perception that the wrong guy broke the record, as most were rooting for Maris' more popular teammate, Mickey Mantle. Note that no other records held asterisks, and that Mark McGwire and Barry Bonds avoided the asterisk by also breaking Ruth's record in runs per game.

Literature

As for times, add the short story 12:01.

Live Action TV

24; and for that matter, The DCU series 52 and the Doctor Who episode "42", as each of these titles is a Shout-Out to 24 due to using Real Time format. "42" was also a Shout-Out to The Hitchhiker's Guide to the Galaxy.
The Heroes episode ".07%".
- This was a reference to the Sherlock Holmes story "The Seven Percent Solution."
The 4400 science fiction series.
The Star Trek: Voyager episode "11:59" and "The '37s."
- Also the TNG episode "11001001."
An enormous number of episodes on The West Wing include numbers, including such titles as Six Meetings Before Lunch, 17 People, and Ninety Miles Away. There are also some named for bills or code names used in the episodes, such as H. Con-172 and 7A WF 83429. The best example of this trope, however, would probably be the fourth season episode Twenty Five.
The Lost episode "316."
The X Files episode "3".
An infamous 1950s game show (along with two revivals) 21.

Music

John Cage's "composition" 4:33, which consists of that exact amount (in minutes and seconds) of complete silence.
- Cage has maintained that the point behind 4:33 is not complete silence, which is unattainable, but rather for the audience to attune itself to the ambient noise of the performance venue itself. This, of course, makes each performance of 4:33 unique.
The Queen song "'39".
The Yes album 90125, which incidentally enough was named after its catalogue number.
Iron Maiden song "2 AM".
Emilie Autumn's "306".
Ken Laszlo's "1 2 3 4 5 6 7 8" (as in counting from 1 to 8, serving both as an Epic Riff and part of the song's chorus)
Van Halen's album "5150", which is also the address of Eddie Van Halen's home studio.
- Maybe later it was, but the album was named for police code for an escaped mental patient.
Toto's albums Toto IV and The Seventh One.
Anthrax's short instrumental "9" from State of Euphoria.
3's and 7's by Queens of the Stone Age
"Strawberry Letter 23", song best-known by The Brothers Johnson
Almos all of the songs in the CD "Revés" from the album Revés/Yosoy by Café Tacvba
Sugar Ray's third album, "14:59," an ironic response to critics who believed the band's fifteen minutes of fame were almost up. (Given the response to their fourth and fifth albums, this title would later prove surprisingly accurate.)
