History Main / EternalEquinox

** ''VideoGame/PokemonDiamondAndPearl'', as well as Platinum, have the seasons mechanic affect the day/night cycle as well, such as night coming earlier and lasting longer when you're in winter.

** Same Venus and Jupiter, with the bonuses of the former having all over it rather uniform temperatures thanks to its dense atmosphere and the latter having a lot of residual heat from its formation that is evenly distributed by its wind producing the same effect.

* ''VideoGame/PokemonGoldAndSilver''/''Crystal'' introduced a built-in clock that has mornings start at 4am and night start at 6pm. This is changed in ''VideoGame/PokemonBlackAndWhite''. The different times of day start and end at times dependent on the season. For example, daytime lasts from 9 am to 7 pm in the summer, but in the winter it lasts from 11 am to 4 pm.

* In every one of the ''VideoGame/StoryOfSeasons'' games, sunrise is 6 AM and sunset is 6 PM, regardless of season. Averted in ''VideoGame/HarvestMoonIslandOfHappiness'' and ''VideoGame/HarvestMoonSunshineIsland''. In those, the times of sunset vary depending on the season. Sunrise is less clear-cut.

* ''VideoGame/TheSims'' games, despite being taking place over a fairly long time in in-game days, uses a fixed day/night cycle throughout. This happens even in The Sims 2 Seasons. Even when in this expansion the seasons changes -and player can choose the seasons desired- with heat, rain and snow, the Earth position doesn't seem to affect the fixed day/night cycle duration.
* In every one of the ''VideoGame/HarvestMoon'' games, sunrise is 6 AM and sunset is 6 PM, regardless of season. Averted in [=IoH=]/[=SI=]. In those, the times of sunset vary depending on the season. Sunrise is less clear-cut.

* ''VideoGame/HeartsOfIronII''. Day and night does vary with latitude, so days are shorter in the Northern Hemisphere. But they're always shorter in the North - apparently it's always winter there.

* The ''Franchise/JakAndDaxter'' series doesn't actually have clocks, but the sun rises and sets in the same interval no matter where you are.

* ''VideoGame/EuroTruckSimulator'' averts it to some degree. Sunset time does not change throughout the year, but does change depending on your latitude. Sunset happens sometime around 9 PM in southern Europe, around 10 or 11 PM in Great Britain, and Scandinavia has midnight sun.

* ''VideoGame/EuroTruckSimulator'' averts it to some degree. It is always summer in the game, but sunset time does depend on your latitude. Sunset happens sometime around 9 PM in southern Europe, around 10 or 11 PM in Great Britain, and Scandinavia has midnight sun.

* ''VideoGame/StarFoxAdventures'' applies this to both the main planet (Sauria) and the satellital regions that were separated from it.

* ''VideoGame/AnimalCrossing'' has sunset and sunrise always occuring at a set time, regardless of latitude or time of year.

* Day and night in ''[[NexusWar Nexus Clash]]'' last exactly one hour each regardless of season. The in-universe explanation is that the cities that become Valhalla aren't really attached to their planets anymore and the day and night cycle are being faked by the PowersThatBe. The real game-mechanics reason for this is that playing a [[OurVampiresAreDifferent Revenant]] usually depends on tracking the cycle to avoid the day and go out at night, and it'd be annoying if Revenant players had to keep track of a bunch of extra mechanics.

Congratulations! Your game's world uses an EternalEquinox. This is when no matter what latitude or time of year it is, the lengths of night and day do not visibly change, no matter where you go or how much in-game time you spend.

* Averted in ''VideoGame/TheLegendOfZeldaMajorasMask'', given that it uses a day/night cycle, but takes place over only a few days, so there wouldn't be as much noticeable variation in times for sunset and sunrise. Played straight in ''[[VideoGame/TheLegendOfZeldaOcarinaOfTime Ocarina of Time]]'', ''[[VideoGame/TheLegendOfZeldaTheWindWaker Wind Waker]]'', ''[[VideoGame/TheLegendOfZeldaTwilightPrincess Twilight Princess]]'', and ''[[VideoGame/TheLegendOfZeldaBreathOfTheWild Breath of the Wild]]'', which also have day and night. ''[[VideoGame/TheLegendOfZeldaSkywardSword Skyward Sword]]'' has both day and night, but you never see the transition from one to the other, so we don't know if this is happening or not. The rest of the series takes place exclusively in daylight.

* The ''Franchise/JakAndDaxter'' series doesn't actually have clocks, but the sun rises and sets in pretty much the same interval no matter where you are.

* Almost-but-not-subverted in ''VideoGame/HeartsOfIronII''. Day and night does vary with latitude, so days are shorter in the Northern Hemisphere. But they're always shorter in the North - apparently it's always winter there.

* Averted in ''{{VideoGame/Dont Starve}}''. Day/night times changes according to the season. In summer days are longer than nights and nights are longer than days in winter.

** And a partial example on the poles, where the days and nights are always exactly six months long.

* Averted in ''VideoGame/TheLegendOfZeldaMajorasMask'', given that it uses a day/night cycle, but takes place over only a few days, so there wouldn't be as much noticeable variation in times for sunset and sunrise.

* Almost-but-not-subverted in ''HeartsOfIron II''. Day and night does vary with latitude, so days are shorter in the Northern Hemisphere. But they're always shorter in the North - apparently it's always winter there.

If it's assumed that everything happens on equatorial latitudes, it can be considered TruthInTelevision. The length of the day on such places varies by much less than one hour throughout the year. This goes completely unnoticed by locals, unlike the actual climate variation, which is influenced by sea and wind currents.

* The ''BattleForWesnoth'' does this. On the associated fora, it was first justified as the result of the granularity of the turns, but then pointed out that at it's apparent latitude and granularity, there should still be noticeable change, but kept as an Acceptable Break From Reality.

* ''AnimalCrossing'' has sunset and sunrise always occuring at a set time, regardless of latitude or time of year.

* ''VideoGame/WorldOfWarcraft'' has day and night changing at the same time (sunrise is at 5:30 AM and sunset is at 6:30 PM; those are Pacific time for non-Oceanic realms and Australian Eastern time for Oceanic realms), regardless of longitude or latitude. That is to say, the days are equally long in every part of the world regardless of the time of the year, and the sun rises all over the world simultaneously.
** In this case, it's justified; some spawns and events are only available during the day or at night, and Blizzard doesn't want to change their availability depending on the time of year.

* ''VideoGame/WorldOfWarcraft'' has day and night changing at the same time (corresponding with the real time based on the server's time zone), regardless of longitude or latitude. That is to say, the days are equally long in every part of the world regardless of the time of the year, and the sun rises all over the world simultaneously.

* CastlevaniaIISimonsQuest: "The morning sun has vanquished the horrible night." Even stranger, there is no twilight period. It goes straight from day to night or vice versa.

* The ''JakAndDaxter'' series doesn't actually have clocks, but the sun rises and sets in pretty much the same interval no matter where you are.

* Survival mode in ''{{Minecraft}}''. A full day/night cycle lasts twenty minutes: ten minutes for day, seven minutes for night, and ninety seconds for sunrise and sunset. Since dangerous monsters come out at night, it's good that the passage of time is reliable day after day.

* Averted in ''{{Dont Starve}}''. Day/night times changes according to the season. In summer days are longer than nights and nights are longer than days in winter.
