Ambiguous Time Period

Mallory: What year do you think this is?!
Archer: I... yeah. Exactly. Good question.

An ambiguous time period is where the series takes place at a certain time in the past or future and in the same universe as ours, except for the story elements added by the author, but doesn't state anything specific. This is either because the time period is completely unmentioned, or because it's mentioned but elements of the story or Word of God state that the fiction uses a different calendar than ours.

Sometimes Anachronism Stew will unintentionally (and sometimes intentionally) confuse viewers into wondering when the work takes place.

This can still happen in works that take place in a completely different universe to ours when there's an overarching timeline, but it's very difficult to pinpoint where in that timeline the events currently being described take place.

When the ambiguous time period is obviously not long ago, it's an example of Present Day Past. Could also be an unofficial form of a Retro Universe. This trope is the temporal version of Where the Hell Is Springfield? Contrast Period Piece and Unintentional Period Piece.

    Anime and Manga 
  • Gundam takes place in the future, but thanks to their excessive use of Alternate Calendar (several, in fact) how far in the future is impossible to pinpoint.
    • Although we do get a few clues. In Mobile Suit Gundam 0080: War in the Pocket it's mentioned January 14th, U.C. 0080 falls on a Monday, while Mobile Suit Gundam ZZ mentions 0088 is a leap year. Apparently somebody once did the math based on this and found 2047 to be the earliest possible date for the changeover (technically, the earliest date would be 2019. The 2047 start date much touted in Fanon is based on some sourcebooks that give 2045 as the last AD date mentioned but don't specify when exactly the switch happened. Sunrise has since declared all timelines that mention the AD era non-canon, though, so now it's anybody's guess).
    • Gundam Wing seems to take place in the mid- to late 23rd century, based off of two pieces of information: the novelization of the series mentions that the circus where Trowa Barton hides out is about to celebrate its 600th anniversary, and the circus' logo (seen in artbooks) has "Since 1667" written on it.
  • There's a split in the fandom as to whether Naruto takes place in a modern day Alternate Universe that lacks certain details (like guns or cars) or in a past with a few modern elements. Rock Lee's Springtime of Youth lampshades this.
  • Inazuma Eleven seems to take place some time in the present to it's release, however in the follow up, Inazuma Eleven GO which takes place 10 years later, the technology is still how it would be in 2008. This is especially jarring whenever you see a character use a cell phone, the show's cast using cell phones actually being the theme of one of the show's endings. And they're all using flip-phones you'd expect to find in 2005.

    Comic Books 
  • The first Dragon Age comic mini-series is notoriously hard to fit into the series' overarching timeline.

    Film — Animated 
  • The Lion King gives no indication of what time the story takes place. There are references that hint it is set in present day. The series confirms this. (On the other hand, since we never see any humans, it's still plausible to depict the setting as taking place in very ancient or even prehistoric times.)
    • A lot of the Disney Animated Canon has this; being fairy tales, they're just set "a long time ago." Sleeping Beauty actually does say "this is the fourteenth century" but most of the rest don't even have that.
  • The original Toy Story obviously takes place in an unnamed Southern California suburb, but timewise it is deliberately vague about its setting. Assuming that Andy is an average little boy and not a nostalgist, it is tempting to take the film's central plot - wooden cowboy toys being suddenly eclipsed in popularity by science-fiction toys - as evidence of a late 1950s setting (and, indeed, the sequel briefly lampshades this possibility). Despite this, though, the world of the movie also features color TV sets, digital readout screens, Heavy Metal music, pizza as a favorite food of non-Italian-Americans note , and the modern version of Mr. Potato Head.
  • The Peanuts Movie is deliberately vague about when it is taking place, aiming for both nostalgia and sense of timelessness that could (with a few exceptions) pass for any era between the 1940s and today. Among the anachronisms are Snoopy still using a typewriter (rare since the 1990s at the very latest), Linus still referring to World War I as “The Great War”, Westerns still being popular (The Lone Ranger is evoked), and interest in the 1960s space program. Accompanying those are more modern or contemporary tropes, such as karate and 21st-century dance pop (which may or may not be perceptible to the characters).

    Film — Live Action 
  • Batman loves this trope. Reporters use very old fashioned cameras and a lot of the film's elements seem to be from The Forties, and yet Batman himself has very modern technology; far better than anything that existed when the movie was made! The closest the franchise comes to explicitly addressing this is in the 1989 original, when a character is shown reading a newspaper from 1947 - but the scene is also set in a newspaper office, where archived newspapers are certainly not uncommon.
  • The Wizard of Oz could take place in 1899 (when its source material was written) just as easily as it could in 1939 (at least in Oz, where the Emerald City's technology is state-of-the art by 1930s standards and the skirts on the women are shorter than the 1890s would have allowed). The simple costumes, rural setting, and old technology (including a horse-drawn carriage) are all pretty vague. Miss Gulch's outfit in particular evokes more of a turn-of-the-century appearance. Of course, it helps that the state of Kansas (except for Kansas City, of course) is even in the 21st century a fairly sleepy place where things tend to stay the same.
  • Dodgeball: A True Underdog Story: Word of God has it that the movie was supposed to take place in the early 1990s, but the case of Anachronism Stew (including Peter renting Mona Lisa Smile on DVD, as well as the existence of digital cable) would suggest otherwise; it pretty much looks as if it could have been set in the present day.
  • Most of the time, The New Adventures of Pippi Longstocking seems to be set around the 1940s (when the first books were written). However, the characters are shocked when a local man "invents" a flying machine and Pippi's sailing adventures with her father seem to be out of the 17th century.
  • 10,000 BC appears to be set in prehistoric times, with the main character encountering both a wooly mammoth and a saber tooth tiger. However, he ends up somewhere that appears to be ancient Egypt or at least Mesopotamia (an emperor is having a large pyramid built).
    • Based on the hints in the story, the civilization is meant to be an Atlantis-like place that gets destroyed in the events of the movie, but inspires the later, historical civilizations.
  • Brazil deliberately invokes this. It's set "Somewhere In The Twentieth Century"- whilst genre convention would normally dictate a dystopia of this type, it's also very Zeerusty and could just as easily be a twisted version of the then present-day world. It's left deliberately ambiguous, and in a way the precise setting isn't meant to be that important.
  • It is hard to pinpoint exactly when Final Girl is supposed to be set. The cars and the dresses the women wear all point out to The Fifties, but the television in William and Veronica’s motel room is in color with a digital display and the guns they use are far more modern than that.
  • A Girl Walks Home Alone At Night: Each character seems to exemplify a different time period in their clothing and demeanor: The Girl, in her striped shirt, short hair, and love of records, seems '60s, Arash loves his '50s clothes and car, Atti looks like she walked out of the 1930s, etc. The actual set looks modern, with oil drills and powerplants in the background.
  • The 1993 film adaptation of The Fugitive plays with this, and not just because it's an updating of a 1960s TV series. The movie does a very good job of not tying the story to any particular time period, partly because the early 1990s (the filming date of The Fugitive and ostensibly its time period) was a fairly conservative era with very few particularly glaring fads or peculiarities and partly because a few subtle retro touches are slipped in, such as a Slavic immigrant who can barely speak English and The Dragon of the evil plot being made up to look like a grotesque Film Noir villain. The most specific technology the movie ever calls attention to is computers - specifically, P Cs with MS/DOS screens and dot-matrix printers, apparently putting the action sometime between 1980 and 1995.
  • Shakes the Clown: The city of Palookaville appears to be stuck at some blurry point between the 1940s and 1960s, with certain characters in suits and fedoras and clowns still hosting children's TV shows - if not for references to Madonna and the Watergate scandal, and cocaine being a recreational drug.
  • Noah is set at some time in the remote past (barring the possibility that what we're seeing is a post-apocalyptic wasteland, of course), but we're not told exactly when. The only compelling clue The Bible offers is that it's definitely taking place before the reign of King David (circa 1000 B.C.); beyond that things get very vague. And given the characters' tribal/hunter-gatherer lifestyle and the fact that agriculture barely exists, it's obviously happening before 3000 B.C. Finally, one animal seen fleetingly in the film appears to be some bizarre prehistoric creature, suggesting that the action is taking place at least several thousand years before the rise of human civilization. So this could be sometime during the late Paleolithic Era, perhaps a few centuries or so before the Western Hemisphere was settled, resulting in a date of, say, 14,000 B.C.
  • Rob Zombie's 2007 reimagening of Halloween did this on purpose. The early scenes of the movie take place 17 years before the rest of the film, but they don't necessarily depict 1990. The fashions, cars, etc are actually mostly (but not totally) 70s-influenced. However, the present day scenes mix in some 90s technology such as cell phones with (then) contemporary fashion and cars.
  • The London scenes of the earlier Harry Potter films are mostly set in areas of old buildings, so time period can be hard for an average moviegoer to determine; the main clues of then-modern times being the cars shown. A brief appearance of the now-demolished Southwark Towers, however, narrows down the possibilities to between 1976 and 2008.

  • Robert E. Howard's Conan the Barbarian stories take place sometime between 20,000 B.C. and 9500 B.C. Or as his short story "The Phoenix on the Sword" puts it, "Between the years when the oceans drank Atlantis and the gleaming cities, and the years of the rise of the Sons of Aryas."
  • Warrior Cats appears to take place in the present day. However, nobody knows how long in the "past" the background lore goes back - Word of God has flip-flopped on whether the Clans have been in the forest for 50 years or 30 years, both of which are considered to be too short by fans considering all the leaders and generation gaps we know about. When you go all the way back - before the Clans were formed, before the Tribe was formed, back when their ancestors lived by the lake - there seems to be modern construction equipment; it describes yellow vehicles. Most people accept the series as taking place slightly in the future because of this, but it's not clear exactly when.
  • In Maggie Stiefvater's The Scorpio Races, the time period is never mentioned. Word of God has said that she knows when it is set, and the location of the island it's set on, but she will not say.
  • Based on the hints, The Quantum Thief seems to take place approximately 300-400 years to the future, but time has become almost irrelevant in a world where most human beings have been uploaded into immortal computer systems that can alter their subjective sense of time by increasing or decreasing processing cycles. The oldest Sobornost Gogols that work in the Deep Time are believed to be at least tens of thousands of subjective years old.
  • It's hard to nail down exactly what period A Series of Unfortunate Events is set in, as "advanced" computers lie alongside telegrams and early mid-19th century automobiles and fashions, as well as practically medieval outlooks on child labour, medicine and the law.
  • It's hard to pinpoint exactly when the stories featuring The Berenstain Bears are taking place. The action never leaves Bear Country, which features very few technologies aside from (early-to-mid-century) cars note  and (pre-1950s) telephones. Shopping malls and color television appear to be fairly new, suggesting an approximate date of 1970; however, one book shows what looks suspiciously like a Rubik's Cube, which was invented around 1980.
  • Diamond Brothers series became this, due to the series schedule slipping a lot. The first book The Falcon's Malteser was released in 1986, so one would think that the series would continue to take place during the 1980s, but then as the books were slowly released, they began to suffer from Time Marches On once the fourth book was released the 2000s. Then when the recent book was released in 2007, one of the brothers had turned an age. It's an '80s/'90s/New Millenium mishmash.

    Live Action TV 
  • Pryors Place falls victim to this: the basic format of the show is Richard Pryor reminiscing about various childhood experiences, however his stories show his childhood friends in obviously 80s attire, not to mention such things as break dancing and arcades exist. It could all be justified, however, in that his stories are fictionalized versions of his life.
  • The U.N.I.T. stories in classic Doctor Who take place sometime in The '70s, or Is it The '80s? Not even The Doctor knows for sure. Not even UNIT itself knows for sure.
  • Similar to the above-mentioned Batman and the below-mentioned Batman: The Animated Series, Gotham's version of its title city has an tons of Anachronism Stew going on; the many retro touches include 1950s (and in some cases older!) music still being popular, mild disapproval (from other gangsters) of a woman wielding great power in the underworld, and Oswald Cobblepot's Ambiguously Jewish immigrant mother. The intent seems to be that Bruce Wayne is Batman in The Present Day, therefore this is The Past, but making it clear when in the past would tie down how long it's going to take Bruce to become Batman. note 

    Newspaper Comics 
  • Ask the average person when Peanuts takes place and they'll state the The Sixties, maybe The '70s. The fashion especially seems to pin the series as averting Comic-Book Time.. Except it doesn't. It's subtle but there are still references that pin strips at certain time periods. Harry Potter was referenced in a late 1999 strip putting the kids at modern day. The earliest strips are obviously set in The Fifties (Davy Crockett caps, etc.), though they still manage to be pretty timeless.
  • The Far Side tries to avoid pop-culture humor in favor of animal or science jokes and generic satire, with the human characters dressing as if it's some point between the 1930s and the '60s. Adding to the confusion are the "historical" strips set in the Stone Age, medieval times, the Old West or whatever, which are sometimes described in the present tense and sometimes in the (implied) past tense.

    Tabletop Games 

    Video Games 
  • Several time periods you visit in Final Fantasy XIII-2 are labeled simply "??? AF" in the Historia Crux, meaning these episodes take place After the Fall but how many years after is unclear.
  • Nigel from The Lost Crown never does get a straight answer when he asks what year is it in Saxton, a region filled with anachronisms due to its numerous hauntings.
  • Live A Live avoids specifying dates at which chapters occur (although the timeframes are much clearer). Logs in the Science Fiction chapter even go so far as to hide dates with X's (although the "copyright" text in Captain Square minigame makes it clear it takes place no earlier than 22nd century).
  • EarthBound takes place in "199X". Its sequel is even less helpful.
  • The Famicom in Madotsuki's room suggests that Yume Nikki takes place at least as far back as The '80s, but it could otherwise be set anywhere between then and the Turn of the Millennium (when the game was made). Just one of the many ambiguous details this setting has to offer.
  • Super Mario Bros. would probably have to take place between approximately 1880 and 1940, when there really were Italian-American plumbers in Brooklyn who talked like that.

  • Word of God states that the calendar saying that the year is 3031 in Ava's Demon is not the BCE/CE calendar we're familiar with.
  • Alice And The Nightmare is rather ambiguous about its period. One one hand, the fashion is victorian and there are carriages used; on the other, there are also mini-fridges, plasma screens and Tron-like suits. The closest we get to a clue is Alice and Edith both reading Lewis Carrol's book.
