History Main / EndlessDaytime

* Places in the far north or far south such as Longyearbyen, Svalbard or Amundsen-Scott South Pole Station experience a "polar day" during the summer months where the sun does not set, and instead just makes a circle in the sky during the course of a 24-hour day. During the winter months, these same areas experience a [[The NightThatNeverEnds polar night]].

* In ''The Memory of Sky'' (a ''Literature/GreatShip'' novel), the HollowWorld is perpetually lit from below, though the light output varies as the hydrogen-breathing plants in the lower section of world (where the sun is) expands exponentially over the course of hours (darkening the world) before igniting into a blazing inferno, wiping everything clean at "noon". In the climax, when [[spoiler: the light is shut off, the human population goes into a wild panic]]

Really long daytime hours are a staple of ScienceFiction. The causes of the everlasting daylight could be anything from having multiple suns to having a HollowWorld with a sun in the center. [[TruthInTelevision On Earth]] there is a phenomenon (pictured) that causes up to several months of nonstop sunshine in certain parts of the world, but this is rarely used as a setting in SciFi. A common explanation is a TidallyLockedPlanet, where one side of the planet will be in perpetual daytime while the [[TheNightThatNeverEnds opposite will be true]] of the other side.

* ''Franchise/StarWars''' Ryloth, the Twi'lek homeworld, a tidally locked planet.

* At certain times of the year in the polar regions of the earth, the sun will be visible for months at a time. This phenomenon is known as [[http://en.wikipedia.org/wiki/Midnight_sun midnight sun]]. Other parts of the year, these regions stay under TheNightThatNeverEnds, where there's no sunrise for up to 4 months and at best there's a bit of twilight to color the sky for a few hours.
* TruthInTelevision for tidally-locked planets. So far, only theoretical, since none of the Solar System's planets are tidally locked to the Sun, but some exoplanets supposedly are.
* UsefulNotes/{{Mercury}}, due to its closeness to the Sun, was for a long time thought to be tidally locked to our parent star, as the only observations that could be made far from the star's glare showed the same surface features. However in the 60s, radioastronomy showed a 3:2 rotation/orbit resonance which complicated the scenario. While the planet's low inclination affords the poles a perpetual day, areas of the equator can experience the sun rising, stopping in its tracks, going back below the horizon and rising again.
* The Moon has a mountain near its south pole that is bathed in near perpetual sunlight (it gets dark there during a total lunar eclipse).
* Interestingly ''not'' TruthInTelevision for [[{{Irony}} planets with multiple suns.]] If the planet orbits both of the stars in a binary system, the suns will always be close together in the sky, and night will still fall. If the planet orbits one of the stars and the other is farther away, it is indeed possible for the two suns to be on opposite sides of the sky and cause almost constant daylight, but...
** An almost full 24 hours (or whatever the planet's rotation period was) of light wouldn't happen all the time, just when the suns were in opposite parts of the sky (in short, only at the right time of year).
** When it did happen, it wouldn't be full daylight all day. There would still be a period of twilight as one sun set and the other rose.
** If the planet and companion star had significantly different orbital inclinations and/or the planet had a high axis tilt, endless day could occur on one hemisphere for decades, but as the other star crossed the ecliptic to shine on the other hemisphere, or moved so that one pole or the other always pointed towards it, just as much time would pass without an endless day.
** In most cases, the other star would be bright enough to see by, but not enough to affect the planet's temperature significantly or allow photosynthesis.
* Reasonably this should be the case given the amount of stars and other light-emitting objects in the universe. The fact that it's not is a [[https://en.wikipedia.org/wiki/Olbers%27_paradox paradox]]. [[note]]It's because the expansion of the universe causes redshift which stretches light waves such that they can no longer be seen by the human eye[[/note]]

* ''VideoGame/ToyStory3'': Played straight in the Wii version, which lacks the time-of-day toggle the PS3 and Xbox 360 versions have and has Toy Box mode permanently set to daytime.

* The ''Literature/{{Pellucidar}}'' novels are set in a HollowWorld that has a sun at the centre. Thus it is always noon in Pellucidar, no matter where you are.

* In Melanesian mythologies it is common for there to have always been day before night was introduced. For example, in the Banks Islands there is a myth where the folk hero Qat retrives night from its land for the benefit of our world, because everyone was tired and bothered by the heat.

* In ''Manga/JoJosBizarreAdventureStardustCrusaders'', while the heroes are traveling through the Saudi Arabian desert, they discover that the sun is continuing to brightly blaze despite it being 8 PM. Turns out it's not actually the sun that's shining, but a powerful enemy Stand; as soon as the user is defeated, the night sky becomes visible.

* ''Series/MidnightSun2016'': As the title suggests, the series takes place in Kiruna, Sweden during the midnight sun, which it won't ever become dark outside until autumn which is several months away. Kahina, a Frenchwoman, has a very hard time adapting.

* The ''VideoGame/FinalFantasyXIV'' expansion ''Shadowbringers'' involves the [[PlayerCharacter Warrior of Light]] and their companions being transported to the First, an alternate version of Hydaelyn that is slowly being consumed by all-encompassing light. As such, it is constantly daytime regardless of the in-game clock - even when the in-game time reaches 6, the time when every other map in the game switches between daytime and nighttime music tracks as the sun begins rising or setting, all that happens in the First is that shadows are cast in a slightly different direction - and the storyline involves the Warrior of Light becoming the Warrior of Darkness and bringing the darkness of night back to the First.

* A humorous example in ''Literature/TheRestaurantAtTheEndOfTheUniverse'': On Ursa Minor Beta it is always 3 O'clock on a Saturday afternoon, except in places where it is Saturday evening.

* In ''WesternAnimation/TheSmurfs'' episode "Queen Smurfette", Father Time fails to bring the close of the day on Smurfette's birthday, resulting in the day never ending until Papa Smurf brings it to Father Time's attention.

** In the episode "[[Recap/TheTwilightZoneS3E75TheMidnightSun The Midnight Sun]]" the Earth is spiraling closer and closer to the sun, and it is perpetually day. [[spoiler: Except it turns out the main character is dreaming, and [[TheNightThatNeverEnds the Earth is actually spiraling AWAY from the sun and freezing.]]]] [[note]]For this to work, the Earth would have to become tidally-locked, meaning the other side would be constantly dark and probably somewhat less hot. [[spoiler:But then, since it's AllJustADream, it doesn't have to be actually physically possible -- and the inverse, what's revealed to be the actual situation, ''is'' possible.]][[/note]]

** In ''[[http://www.equestriadaily.com/2011/06/story-solar-eclipse.html Solar Eclipse]]'', [[LightIsNotGood Princess]] [[RonTheDeathEater Celestia]] refuses to lower the sun and bring about everlasting day.

* ''Machinima/RedVsBlue'': The denizens of Blood Gulch (and later Valhalla) occasionally complain that the sun never sets in their canyon. This is mostly a bit of meta humor pointing out that the maps in Franchise/{{Halo}} don't have a day/night cycle.

* In ''Anime/DragonBallZ'', the planet Namek has three suns shining on it from all sides, keeping it in perpetual daylight.

Powerful beings will occasionally threaten to invoke Endless Daytime as a punishment or a show of power. This is uncommon, though, and when this ''does'' happen, it's more in the vein of "Hah! Look what I can do!" rather than "You'd better do what I say or else". This likely has to do with the fact that [[MostWritersAreHuman humans are generally diurnal]] and psychologically [[LightIsGood associate daytime with positive things like warmth, happiness and growth]]. In fact, it's far more likely for [[AGodAmI godlike beings]], the BigBad, {{Sufficiently Advanced Alien}}s, and {{Eldritch Abomination}}s to attempt to bring on [[TheNightThatNeverEnds eternal night]] instead.

* In ''Manga/OnePiece'', the judicial island Enies Lobby is always in the sunlight at all hours of the day or night, which is the reason for its nickname of "the nightless island". It's referred to as a ''type'' of island, one of many forms of WeirdWeather in the Grand Line, suggesting there are other islands which never have night either.
* In Part 3 of ''Manga/JoJosBizarreAdventure'', while the heroes are traveling through the Saudi Arabian desert, they discover that the sun is continuing to brightly blaze despite it being 8 PM. Turns out it's not actually the sun that's shining, but a powerful enemy Stand; as soon as the user is defeated, the night sky becomes visible.
