* In ''WesternAnimation/GravityFalls,'' Stan and Ford's mother was holding a baby when Stan was kicked out of the house--presumably this is Shermy, grandfather to Dipper and Mabel. "More than ten years" pass before Stan and Ford see each other again, and then thirty before Stan can free Ford from the portal. At which point Shermy is about forty, but with twelve-year-old grandkids? Even if you assume that "more than ten years" was closer to twenty, that's cutting things pretty close.

* ''VisualNovel/ZeroTimeDilemma'' deals with a lot of science and math, both basic and advanced (mostly done by [[BrainyBrunette Akane]]), and most of the time it gets it right, but two mistakes managed to slip in:
** If you fail to get the correct code in the pantry, Carlos will say that a 4 digit-code has "hundreds of thousands of possible combinations". No, it doesn't: it has exactly 10,000 combinations. Akane makes a similar mistake in the infirmary when she claims there is ''over'' a thousand possible combinations for a 3-digit code when it's ''exactly'' one thousand combinations.
** At one point, Akane says that the probability of getting 3 ones by throwing three dice at once is 1/216 (which is correct) but attempting it three times would give 1/72 chance, which is close but not entirely correct. The probability of getting at least one success with three attempts is 1 minus the probability of failing three times in a row. In this case it's 1-(215/216)^3, or more precisely 139,321/10,077,696, which is slighly lower than 1/72.

** At one point in ''VisualNovel/NineHoursNinePersonsNineDoors'' Seven pulls up a theory that the ship they're on is RMS Gigantic(a real-life ship that was later renamed to HMHS Britannic), to which Santa reacts with "There is no way we're on a boat that's almost 100 years old". Gigantic was finished in 1914 and game takes place in 2027, so if Gigantic still existed it would be ''over'' 100 years old.

* ''Film/SpiderManHomecoming'': The timeline for the film is messed up within the opening scenes. The film opens with Toomes and his crew cleaning up the fallout from the [[Film/{{TheAvengers2012}} Battle of New York (which has been confirmed to be set in 2012)]]. Despite this, the film repeatedly states it is set eight years after ''The Avengers''. This is impossible, as Homecoming begins two months after ''Film/CaptainAmericaCivilWar'' (2016, four years after the Battle of New York); but in that movie Vision makes a reference to Tony Stark revealing himself as Iron Man to the world eight years earlier, even though ''Film/IronMan'', which is understood to be set in either 2009 or 2010 (although the film was released in 2008). The alternative is that the Phase One movies have [[{{Retcon}} retroactively]] been pushed [[Main/ComicBookTime further back in time than previously stated]], so either way there are inconsistencies.

* A definite example exists in ''Disney/BeautyAndTheBeast'' at the beginning of the film, the enchanted rose is explicitly stated to bloom until he was twenty one years of age. It has already started to wilt and lose its petals because this is the final year. The song "Be our Guest" has Lumiere state that they've been cursed for ten. It's very clear that the prince is running out of time to break the spell, but it also means that he was eleven years old at the time he was transformed into the Beast. True to the trope, he looks and acts far older in ''Disney/BeautyAndTheBeastTheEnchantedChristmas'' which depicts the night he was transformed. He certainly doesn't sound eleven and he hardly looks prepubescent.

* Tony Rothman holds a doctorate in physics ... but in his novel Literature/TheWorldIsRound an AI expresses times in "light-meters", with an embarrassing error: the AI sais something is not scheduled for some "ten to the fifteenth light-meters", which he then says is "a few years". It's actually only a little over a month.

* In the ''WesternAnimation/KimPossible'' episode "Ron Millionaire", Ron becomes NouveauRiche after receiving $99 million in proceeds from [[InventorOfTheMundane his invention of the Naco]]. At one point in the episode, Kim quips that he's "just south of billionaire", but that isn't true. What $99 million is actually "just south of" is $100 million, which is only 10% of the way to becoming a billionaire.

* In the ComicBook/{{New 52}}, Bruce Wayne has only been Franchise/{{Batman}} for six years. That he managed to have four Robins in that time is unreasonable, but not impossible. However, he was already Batman when he fathered Damian... who is twelve years old. They later attempted an AuthorsSavingThrow by establishing that Batman has been active for much longer than six years, but was only considered an {{Urban Legend|s}} prior to that, but even ''that'' was proven false with SCott Snyder's "Zero Year" arc. Then it was just impied that Damian had accelerated aging.

** In ''Literature/QuidditchThroughTheAges'', it says that the first ever World Cup was in 1473, with a match being held every four years. Yet the World Cup in ''Goblet of Fire'', set in 1994, is number 422. There can't be 422 world cups in 521 years with a four-year gap in between[[note]]There are tourneys [[http://en.wikipedia.org/wiki/Copa_América#Results which had erratic patterns before getting into regular intervals]], but that's a detail[[/note]]. Calculated correctly, the World Cup that the Weasleys, Hermione, and Harry attend is actually the 131st, and it would have been held in 1993.

* ''The Flash'' created a huge problem for itself with Wally West II. Originally, Wally II was the New 52 Wally West, the thirteen year old son of Rudy and Mary West and nephew of Daniel West, the Reverse-Flash. Then ''Rebirth'' happened and brought the original Wally back, retconning Daniel into being Wally II's dad while also giving Wally II an AgeLift so that he's sixteen. The problem is, a key part of Daniel's backstory is that he's a CosmicPlaything, and he ''explicitly'' states that he was caught by the Flash on his eighteenth birthday, which meant he was tried as an adult. He spent five years in prison, and when he's released, he becomes the Reverse-Flash not long after, and current stories took two years two play out. Unless it took ''years'' for Daniel to be convicted of robbing a bank, he'd have had to conceive Wally II ''as a child''.

** Konoha's ninja population seems iffy. During the 4th Shinobi World War, we are told that the Allied Forces comprise some 80,000 ninja and samurai. Konoha [[WordofGod supposedly]] has the largest population of any ninja village, but even if each village and the samurai contribute the same amount of soldiers, Konoha would still have to have at least 13,000 nin. Though we only ever see [[EconomyCast the same 50 Konoha ninja]], this is still possible. It's just that, according to Kabuto, there were 87 Konoha genin in the Chunin exam and, even accounting for genin who couldn't or didn't want to particpate, that seems like an incredibly small ratio. At the time of the chunin exams, the Rookie 9 are apparently the ''only'' new genin in Konoha. The exams are done twice a year, so that would mean that Konoha graduates ''at most'' 18 ninja a year. To put this in perspective, it would take 723 years to get 13,000 ninja this way.
** Konoha in its entirety has been shown in the manga and databooks, and it contains only a few hundred small buildings. So it would be unlikely that it accommodates a population of ten thousands Shinobi.

So it would be unlikely Uchiha Clan Massacre) that it accommodates no doubt had taken out a population large chunk of ten its ninja population...
** Even disregarding the above, Konoha, with its several hundreds-odd non-high rise buildings [[spoiler: until the ''Boruto'' series]] (since it's still technically, y'know, a village), doesn't seem to be the type of community that could support tens of
thousands Shinobi.of commoners, let alone ninja, though this can be easily handwaved by thinking that Konoha ninja don't necessarily all come from the village and instead hailed from elsewhere in the Land of Fire.



** The matter of Ron's older brothers, Bill and Charlie: originally, Rowling stated that Charlie was two years older than Percy, and Bill was two years older than Charlie. However, Percy is in fifth year in ''Philosopher's Stone'', meaning that Charlie should have either been in seventh year, or just graduated. She later corrected this to Charlie being three years older than Percy -- which is still impossible, as the Gryffindor Quidditch team has allegedly not won the Cup since Charlie stopped playing for them, and the period of time since Gryffindor has won is given in "Prisoner of Azkaban" as having been seven years, coming up on eight (or four years before the start of the first book). Charlie would have had to have left the team in his third, or possibly fourth, year for his age at three years older than Percy to be plausible -- unlikely, since he was Quidditch Captain and "could have played for England". Bill was born in 1970 and would have finished in 1987 (four years before PS, not 8), Charlie was born in 1972 and would have finished in 1989 (2 years before PS not 8), Percy in 1976, Fred and George in 1978, Ron in March 1980 and Ginny in August 1981.
