Quite simply— When a character's life seems to 'jump'. They are at work and then suddenly they are at home, with no memories of what happened in between. Sometimes the memories will come back in the form of flashbacks. This can happen for many reasons— memory damage, aliens, trauma, possession, or multiple personalities, just to name a few. Truth in Television, black outs, that is alcohol-induced amnesia, have let many people hear great stories about themselves after they woke up in completely different places for decades. Also occurs in those that have Dissociative Identity Disorder, waking up to find themselves in different places then they originally were doing something completely different from what they last returned. What Did I Do Last Night? is the lighter and/or more comedic version of this trope, usually related to drinking too much (see also Binge Montage). See also Alternate Identity Amnesia, a supernatural cause for Missing Time. Differs from other amnesia tropes in that only a few minutes or hours goes missing.

Anime & Manga
- In Lupin III: Sweet Lost Night,note Lupin loses 12 hours, waking up in the middle of a busy street, with Fujiko complaining that he betrayed her. Half of the movie deals with Lupin trying to figure out what had happened in these twelve hours, and what to do if it happens again.
- It's implied that this happens to Bakura in Yu-Gi-Oh! whenever he gets possessed by his dark side. It's very obvious that this is the case when Yami Bakura suddenly relinquishes control during his duel with Yugi in the second season. Poor Bakura is completely bewildered, having suddenly woken up on top of a blimp with a bleeding arm, with apparently no idea how he got there and why. Also, this happened to Yugi during the early volumes of the manga whenever he got possessed by the puzzle.
- In Trigun, Vash the Stampede has a bit of a problem with this whenever his more high-level powers get unlocked, until he learns to do it on purpose. Since both this incidents involve psychic powers being used to make him blow up a city with his right arm, which transforms into a BFG for the purpose, it's unclear whether the cause of these gaps is the psychic trauma, the emotional trauma, or the physiological trauma. Or the combination.
- Anya in Code Geass suffers from this periodically, and has made it a habit of keeping a blog of pictures from her daily activities so she knows what she has been doing. This is revealed to be a result of Marianne actively possessing her body, during which Anya has no memories.
- In Animal Man #19, the title character, as he gradually approaches Medium Awareness, wonders why his life seems so episodic and fragmentary:
What if we're just characters and not people? [...] A few months ago, or maybe it was a year or more, my wife was attacked and almost raped in the woods. There were four guys. What happened to them? [...] Why was there no trial? [...] Why is my life so...so disconnected? One minute I'm at home, the next I'm in the Faroe Islands or in Paris and I think I remember how I got there but I don't really know.
- Dave in Brainbent experiences this, and in one particularly frightening instance cuts his hand while home alone and then loses time, meaning he could have bled to death and not even known it.

- In Like Flint. While playing golf with the U.S. President, Z.O.W.I.E. chief Lloyd Cramden uses his stopwatch to time the President's golf swing.

- Aaron Stampler in Primal Fear mentions that he "loses" time over his childhood. This is explained as his alter-ego taking over during times of stress.
- This is something that the title character must deal with in the domestic drama Regarding Henry, starring Harrison Ford.

- This happens to Eddie in Limitless when he starts taking too much NZT.
- Robert A. Heinlein's novella "The Unpleasant Profession Of Jonathan Hoag"
- In The Wheel of Time, Mat Cauthon stumbles into a town that has been inexplicably cursed with a very specific form of societal breakdown: everyone loses control over himself at sundown, kills other people and is killed, then wakes up in his bed with no memory of what just happened. Every. Single. Night. When people try to leave, or kill themselves, they just wake up in bed the next morning.
- In Lois Duncan's Down a Dark Hall, the girls in the school are possessed by ghosts randomly, and they have don't remember anything that happens while possessed.
- This is apparently what Ginny's possession in Harry Potter and the Chamber of Secrets looked like from her end, based on her account from three books later: "When he did it to me, I couldn't remember what I'd been doing for hours at a time. I'd find myself somewhere and not know how I got there."
- Under the Volcano is a stream-of-consciousness novel from the point of view of several characters. One of them is a severely sodden alcoholic, and his sections contain much confusion and some unexpected leaps in time.

- In the Star Trek: Millennium trilogy, it's revealed that neither Odo, Quark nor Garak can recall what happened the night of the Cardassian withdrawal from Terok Nor.

His attempt to find answers irritates Odo and Garak, who refuse to discuss or acknowledge that they're in the same situation.

- Suffered by Dave at one point in John Dies at the End.
- In Galaxy of Fear, Tash once hits her head. Her memory of the past hour or so becomes blurry, so she has some doubt about if she's a Tomato in the Mirror.

- Happens a few other times on TNG (at least!).

- Happens again to the Crew of the Enterprise-D in Clues, they find that a whole day seems to be missing and Data is acting very strangely and disobeying orders.
- In Hannibal, Will Grahams starts losing time as his mental health deteriorates.

- In the Supernatural episode "All Hell Breaks Loose, Part One" (S02, Ep21), the is Played Straight for Sam who wakes up the next day in Cold Oak, South Dakota.

- Doctor Who: Unexplained skips are a frequently clue that a character has suffered memory alteration of some sort. It's particularly noticeable in Season 6 of the new series, when the Doctor and companions face off against the Silents, beings that erase your memory of them the instant you are no longer looking at them. This is played for copious Paranoia Fuel toward the end of the season, with characters abruptly realizing that they've moved, or fought, with no memory of having done so.
- Dream Theater's song "Losing Time" mentions this, as it is about Multiple Personalities.
- Classic Traveller Adventure 4 Leviathan.

- This happens quite frequently to the characters of Marble Hornets when they are exposed to elements of the supernatural. Most notable are Jay, who loses seven months of his memory after running at the Operator; Jessica, who also loses her memory around the same time as Jay; and Tim, who frequently wakes up in unknown places with huge gaps in his memory as a result of his masked persona taking over. The other members of the Marble Hornets cast also get this, to varying degrees.
- Happens in Brennus to the main character and his sister. Doesn't help that they forget that they've forgotten things, and need someone to talk about what they were doing to even realise they don't remember it.
- This is a common trait of UFO accounts.
- Missing time can result from much consumption of alcohol, use of drugs, or being under general anesthesia during surgery. The first two probably help explain the point directly above this one.
- This can also be an effect of hypnotism or other altered mental states.
- Trauma to the brain can induce amnesia in retrograde (the inability to remember some events prior to the blow) or anterograde (the inability to form new memories) form. Both are forms of time elapsing without people having any memory of it. Severe anterograde amnesia can result in missing time from the time of the event until whenever now is. If new memories can't be formed, then you just woke up in the hospital five minutes ago... forever. Seems like And I Must Scream to us, but the sufferer would never know.
- A minor case of this can happen if you walk/travel to school/work and back home every day. While the things you do at school/work and at home are usually not the exact same every day, the walks/travels can easily be extremely similar from day to day. At a point, the walk/travel may be so ingrown of a habit that you some day realize "hey, I thought I only just left my home, but I'm already at work" because you did the travel with pure muscle memory (it is especially likely to happen if it's early morning and you're too tired to pay attention to your surroundings).
