Who needs [[{{Seers}} precognitive powers]] when you've got TimeTravel?

A character goes back to the past. From the other character's point of view, they seem to say, do and know things that imply a frighteningly accurate knowledge of the future. Of course, they do not need special powers to be able to do this -- they only need to ''remember'', because [[TheSlowPath they have already lived though it before]]. If their chosen method of time travel is easily accessible, they can even try to "{{save|Scumming}}-scum" their lives so that it follows an ideal path.

A variation is a character who is TrappedInThePast before their actual date of birth, but in a period that they are familiar with from history books. They may also be able to make use of a ConvenientEclipse if they remember the exact date when it is due to happen.

Note that you should not even attempt this without significant historical research under your belt, and even then, people have messed around with historical dates so often during the times and truth intermingled with myth so much that it will probably not do you a lot of good anyway. (We would also mention things like the language barrier, but those belong to the main TimeTravel trope.)

Not to be confused with "retroactive clairvoyance", an entirely different term that has been used for the act of retrofitting vague predictions to events that have already happened.

If the character relies on science and engineering from the future, rather than knowledge of the current time period, they are GivingRadioToTheRomans. Often overlaps with the GroundhogDayLoop in those cases where the character is actually aware they're reliving the same day over and over again.

Characters UnstuckInTime or afflicted with certain forms of MerlinSickness may exhibit similar abilities.

'''Warning''', spoilers below.



* ''VisualNovel/HigurashiWhenTheyCry'' gives us [[spoiler: Rika]], with emphasis of the frightening.
* In ''Anime/PuellaMagiMadokaMagica'' this is the first hint that something is wrong about [[spoiler:Homura]].

* Layla Miller of ''ComicBook/XFactor'' knows stuff because [[spoiler: a version of herself traveled eighty years into the future and learned stuff and then told her past self.]]
* In modern age comics [[TheFlash Barry Allen]] and many of his family member know the future, at least in vague terms, due to spending so much time in the 31st century. Barry himself was able to make use of this knowledge even after his death by time traveling to important events while he was still alive.

* In ''Fanfic/MementoVivere'', a VideoGame/FinalFantasyX fanfiction, Rikku helps Braska's group figure out how to get through [[spoiler: Bevelle’s Cloister of Trials]].

[[folder:{{Film}} - Live-Action]]
* Done frequently in ''Film/BackToTheFuture'', as Marty accidentally blurts out the fates of the people he's meeting in the past.
-->"That's right, he's gonna be mayor!"
* In ''Film/GroundhogDay'', Phil lives through the day over and over again and thus knows everything that's going to (or even ''could'') happen that day.

* In ''Literature/LestDarknessFall'', 1930s archaeologist Martin Padway is mysteriously transported to 6th Century Italy (where the "Dark Ages" are about to come down with a vengeance). He is able to use his knowledge of classical history to pull this off a good deal.
* In ''Literature/TimeEnoughForLove'', this is how archprotagonist Lazarus Long hopes to survive and prosper in the 1920's United States, since that's when he grew up and he has extensive period and personal knowledge of the era. Two things foil him: first, he arrives too early due to a miscalculation and winds up in 1916, on the cusp of U.S. involvement in UsefulNotes/WorldWarI. Second, he falls in love with his mother Maureen and, in a [[LoveMakesYouDumb misguided attempt to impress her]], enlists in the army. However, he does entrust to Maureen a wealth of information on the future history of the United States in that timeline, allowing her to quietly abet several key events that help things [[YouAlreadyChangedThePast turn out the way they should]].
* Literature/TimeScout's scouts and guides really want to take advantage of this. They want to see and observe important historical events first hand. In the series, the only time it's deliberately taken advantage of is by the Ripper Watch Team, finally learning who UsefulNotes/JackTheRipper was.
* In ''Literature/WarriorCats'', a bunch of characters are shocked when the time-traveling main character tells them where humans will build a barn and that off in the mountains there's a place they can live. Turns out that he's just speaking from his own experiences; he's far in the past.
* This is the TwistEnding to ''[[http://mightygodking.com/index.php/2009/11/10/scenes-from-an-alternate-universe-where-the-beatles-accepted-lorne-michaels-generous-offer/ Scenes From An Alternate Universe Where The Beatles Accepted Lorne Micheal's Generous Offer.]]'' [[spoiler: Ringo managed to go back in time and tell his past self what to do in order to bring the Beatles back together. It ends with the new Ringo doing it again, in order to make an even better universe.]]
* The ''MagicTreeHouse'' book ''Civil War on Sunday'' has a minor example in Jack telling a wounded soldier that someday the war will end and so will slavery. The soldier then asks him if he can see the future, to which Jack replies "In a way."

* On ''Series/BabylonFive'' [[spoiler:all the various Minbari prophecies were actually made by Sinclair, who traveled into the past and became Valen. The prophecies simply predict what he knew would transpire in the future.]]
* ''Series/DoctorWho'', both old and new, does this all the time. In particular, the Third Doctor frequently remarked on how "primitive" Earth technology was during his exile in the 1970s.
** Although it's debatable whether this is by comparison to humanity's future or to his native Gallifrey (which would make this more a case of [[CulturalPosturing Cultural Posturing]]).
* ''Series/QuantumLeap'' invokes this trope on occasion. For example, once Sam made a bet that Gerald Ford would trip going down the stairs out of Air Force One, which, of course, then happens.
* ''Series/{{Lost}}'' Season 5 did this a lot once the Time-Travel started.
* In ''Series/StarTrekDeepSpaceNine'', there's seldom actual time travel involved but the [[TomesofProphecyandFate various Bajoran prophecies]] were made by ancient Bajoran clerics who received visions of the future from the Prophets, [[NonLinearCharacter who exist outside of time]] so it's much of a muchness to them. Presumably, they received these visions during orb experiences. For instance, Trakor's First Prophecy states that the [[TheChosenOne Emissary]] will find the Celestial Temple and the Prophets will gave him his life back. This happens thousands of years later, in 2369 as depicted in the pilot "Emissary", when Sisko discovers the wormhole. His encounter with the Prophets helps him to realise that it is time to stop living in the past and get on with his life. Consequently, PropheciesAreAlwaysRight though they're usually rather vague and there is the occasional PropheticFallacy and/or ProphecyTwist during the series.

[[folder: VideoGames]]
* In ''VideoGame/ChronoTrigger'', Magus ends up in the past (ironically, coexisting with himself when he was a young boy), and uses his knowledge of the future (which he experienced as a young boy) to gain himself the position of a prophet in the royal palace.
* A key gameplay mechanic in ''VideoGame/RadiantHistoria'', where the protagonist has the ability to jump to certain times and places in his life in order to SetRightWhatOnceWentWrong. Gets a double-dose because there are two timelines which are linked together, so progress in one provides hints as to events that may occur in the other.
* A GroundhogDayLoop version of this happens in ''VideoGame/TheLegendOfZeldaMajorasMask''. Learning where everyone in Termina is going to be during the three days you're in Termina is crucial to some of the sidequests.
* ''VideoGame/{{Undertale}}'' {{Lampshades}} this. After the first playthrough of the game, some characters will occasionally make comments that the player character seems to usually know what's about to happen, as though they've seen it all before.

* Archer in ''VisualNovel/FateStayNight'' knows all about Shirou's abilities, how he will injure himself with projection, the identities of Heroic Spirits who haven't revealed themselves, Saber's backstory, what the Grail really is, etc. [[spoiler:Hint: He's Shirou from the future, so he not only lived through what is basically the Fate path, he's also had time to research on people he saw then like Caster and then correctly identify her as Medea.]] He also knows lots about the Big Bads' plots before they implement them and whatnot.
* [[spoiler:Akane]]'s attempts to use this trope to alter the timeline form the main plot of ''VisualNovel/NineHoursNinePersonsNineDoors''.
** Repeated in the sequel, ''VisualNovel/VirtuesLastReward''... well, [[MindScrew kinda]]. [[spoiler: The purpose of the second Nonary Game was Akane teaching Zero how to alter the past using MindSwap on his younger self, so that his younger self would get the experience necessary to survive another Nonary Game which he would've been a part of had he not swapped minds with his older self, who would know how to survive the Decision Game in ''VisualNovel/ZeroTimeDilemma'', thereby preventing the release of Radical-6]].

[[folder:Web Comics]]
* The time-traveling Cassie Wells of ''Webcomic/TimesLikeThis'' has used warnings from her future self to stay away from bad mistakes ... such as [[http://www.timeslikethis.com/?id=329 knowing ahead of time which men in a bar are safe to cruise,]] and which are married, potential date-rapists, or otherwise trouble. She [[http://www.timeslikethis.com/?id=289 deliberately avoids telling herself who she will fall in love with for good,]] afraid that if she knows, she'll screw it up. And the fact that no one has shown up from the future to tell her, suggests that her willpower is fairly strong on this point.
* Kevyn Andreyasn in ''Webcomic/SchlockMercenary'' travels back in time with a database of news reports and other information, after saving the galaxy he uses lottery numbers to make a lot of money (which ends up getting him in trouble with TheMafia). The version of Kevyn from the past uses stock market information from the same database to also make a lot of money (which mostly gets spent saving Tagon).

* ''Machinima/RedVsBlue'': Wyoming uses his time distortion unit to keep looping time whenever he gets beaten by Tex and the Blues, allowing him to foresee several of their plans (for example, he knows where Tex is hiding with her invisibility unit, and knocks her out). However, thanks to a special ability of his LaserBlade, Tucker has RippleEffectProofMemory, and uses this trope to his advantage to kill Wyoming and save Caboose's life.
