History Main / YearX

* ''Literature/TreasureIsland'' also takes place "in the year of grace 17--."

** The fangame ''VideoGame/Mother4'' is set in 197X.

* In ''Manga/YuriIsMyJob'', the results for the Blume election were tallied on "May XX, 20XX." Somewhat unusually, even the day of the month is Xed out (although it's probably some time after Golden Week).

** ''VideoGame/Persona5'' doesn't give us the exact year other than "20XX", in contrast to the previous ''[[Franchise/ShinMegamiTenseiPersona Persona]]'' games, but the in-game calendar is identical to the 2016 calendar, meaning the game takes place 4 years after the end of ''VideoGame/Persona4''. The nonspecific year can be likely attributed to Creator/{{Atlus}} originally intending to release ''Persona 5'' in 2014 and presumably have it take place in 2016, which would fit the NextSundayAD time frames of ''VideoGame/Persona3'' and ''4''. {{Schedule Slip}}s led to ''5'' not actually releasing until 2016 - the year it takes place, rather than shortly in the future like previous games. In ''VideoGame/PersonaQ2NewCinemaLabyrinth'', when the female protagonist of ''Persona 3 Portable'' says she came from 2009, and the cast of ''Persona 4'' say they're from 2011, the Phantom Thieves only say that they didn't come from either of those times.

* In ''Fanfic/NeitherABirdNorAPlaneItsDeku'', the setting's year is referred to as 20XX. All Might's car was only manufactured in 198X and the old Beebo cartoon ran in the 19XXs. It's implied that the story still takes place in the 21st century, as the Justice Society of America formed with the blessing of UsefulNotes/FranklinDRoosevelt.

* The [[http://www.loc.gov/standards/datetime/ Extended Date Time Format]] used by the Library of Congress uses X to denote unspecified digits. The upcoming revision of the international standard [[https://en.wikipedia.org/wiki/ISO_8601 ISO 8601]] will also incorporate the same notation.

* The future sometimes seen in Creator/AlEwing's ''Comicbook/Avengers'' titles (the one where Dani Cage is Captain America, fighting the Golden Skull), is set in the year 20XX, presumably to ensure the [[ComicBookTime sliding timescale]] never actually reaches it.

* In ''[[Creator/RankinBassProductions Rudolph's Shiny New Year]]'', the new year is "19-Wonderful".

* The Creator/ImageComics CrapsackWorld FeudalFuture series ''{{Comicbook/Lazarus}}'' is built entirely around this trope, with "Year X" having been the year that mega-corporations swooped in and took advantage of global political instability to divide the entire world up among themselves. The book begins in X+64, and as of the new ''Risen'' arc, has reached X+68

* ''VideoGame/FinalFantasyXIII2'' subverts this trope with several [[TimeTravel destination times]]. Whenever Serah and Noel [[SetRightWhatOnceWentWrong change the future]], the destination year is marked with X's in place of zeroes in the Historia Crux. However, this is because [[GameplayAndStorySegregation the player retains access to the unchanged futures]], and serves only as a differential. So 400 AF and 4XX AF take place in the same year; they're just in different timelines.

* In the Brazilian classic ''Captains of the Sands'', the only temporal reference is the death of protagonist Pedro Bala�s father, said to have been killed during the 191... strike.

** ''VideoGame/Persona5'' doesn't give us the exact year other than "20XX", in contrast to the previous ''[[Franchise/ShinMegamiTenseiPersona Persona]]'' games, but the in-game calendar is identical to the 2016 calendar, meaning the game takes place 4 years after the end of ''VideoGame/Persona4''. The nonspecific year can be likely attributed to Creator/{{Atlus}} originally intending to release ''Persona 5'' in 2014 and presumably have it take place in 2016, which would fit the NextSundayAD time frames of ''VideoGame/Persona3'' and ''4''. {{Schedule Slip}}s led to ''5'' not actually releasing until 2016 - the year it takes place, rather than shortly in the future like previous games.

* In ''TabletopGames/HaltEvilDoer'', the Near-Future Dystopia (think ''Comicbook/Marvel2099'') is sometimes referred to as taking place in 20XX. Sometimes heroes from the present might learn the actual year, but then they return to the present and change things, and it's XX again. Similarly, the Future of Wonders (think ''Comicbook/LegionOfSuperheroes'') is sometimes called 2XXX.

* ''Manga/HellstarRemina'': [[spoiler:Earth]] is eaten in "July 20XX".

* ''VideoGame/RiverCityRansom'' takes place in the year 19XX. The sequel, ''VideoGame/RiverCityRansomUnderground'', takes place after a TimeSkip of 25 years... in the year 19XX.

** ''VideoGame/Persona5'' doesn't give us the exact year other than "20XX", in contrast to the previous ''[[Franchise/ShinMegamiTenseiPersona Persona]]'' games, but the in-game calendar is identical to the 2016 calendar, meaning the game takes place 4 years after the end of ''VideoGame/Persona4''. The nonspecific year can be assumed to be attributed to ''Persona 5'' originally intended to be released in 2014 and presumably take place in 2016, which would fit the NextSundayAD time frames of ''VideoGame/Persona3'' and ''4''. {{Schedule Slip}}s led to ''5'' not actually releasing until 2016 - the year it takes place, rather than shortly in the future like previous games.

[[folder:Live-Action TV]]
* ''Series/PowerRangersRPM'' was set in 20XX (between late 2040 and 2096).
* The ''Series/DoctorWho'' episode "The End of The World" takes place in "5.5/Apple/26", although this may be another term for [[ExtyYearsFromNow exactly 5 billion years]] after the characters had left.
* ''Series/ServantOfThePeople'' features a subtle version of this, with a small poster that has the year on it, but the part with the last digit is torn off. The show is basically set in 201X.
