History Main / NightAndDayDuo

* The Zababa duo in ''Anime/SenkiZesshouSymphogear'' has this as one of their more prominent duality motifs. Kirika Akatsuki is an energetic girl with a last name that means "dawn," blonde hair, and a very physical fighting style involving various polearms; Shirabe Tsukiyomi is dark-haired, stoic, takes her last name from the Shinto moon god and uses a highly mechanized gear [[PowersDoTheFighting that can do most of her fighting automatically]]. To drive the point home, their respective battle songs in season four are titled "Dangerous Sunshine" and "Melodious Moonlight."
* In ''Manga/{{Boruto}}'', Mitsuki and his older "brother" often refer to himself as a moon, meant to be illuminated by the light of his sun, Boruto.

* ''Literature/KitWilliamsMasquerade'' features {{Anthropomorphic Personification}}s of the Sun and the Moon. The Moon sends her servant [[MoonRabbit Jack Hare]] to tell the Sun she loves him, which is where the plot starts.

* Myth/NorseMythology: Sol (sun goddess) and her brother Mani (moon god) form a pair. Both of them emerged at the creation of the universe and ride across the sky on horse-drawn chariots in order to tell the days for man.

* Hylas and Pirra, the protagonists of the ''Literature/GodsAndWarriors'' series, have this dynamic built between them, and it's lampshaded in-universe in the penultimate book, ''The Crocodile Tomb''. Hylas is a yellow-haired and tawny-eyed Outsider from Lykonia's mountains, while Pirra is a black-haired and dark-eyed daughter of Keftiu's High Priestess with a crescent scar on her cheek. Hylas' main animal companion is Havoc, a lioness from Thalakrea's volcano island, and lions are sacred creatures of [[GodOfFire the Lady of Fire]] and Sekhmet, the lion-headed solar deity from Egypt. Pirra's main animal companion is Echo, a falcon from Keftiu (a country that worships the Sea), and falcons are sacred creatures of Heru, the falcon-headed Egyptian god whose domain includes the Moon.

* The Mirage set of ''TabletopGame/MagicTheGathering'' has several cards which reference the [[https://magic.wizards.com/en/articles/archive/love-song-night-and-day-2003-04-14 Love Song of the Night and Day]] which definitely falls under this trope.
* The gate city of Ecstasy in ''TabletopGame/{{Planescape}}'', where the Outlands meet Elysium, is ruled by the Sun Master and the Dark Hunter.

* The alien pets Sunspot and Moonbeam of ''WesternAnimation/ReadyJetGo'' are associated with the sun and moon through their names and colors ([[OrangeBlueContrast Sunspot is orange, black, and white; Moonbeam is purplish-blue and white.]])

* ''Manga/{{Haikyuu}}'': This motif is present in the contrast between Karasuno's two freshman middle blockers, Hinata [[note]]written with the kanji for "sun"[[/note]], who is friendly, vibrant, and warm, and Tsukishima[[note]]written with the kanji for "moon"[[/note]], who is cold, aloof, and distant. It's even acknowledged in-series.

* Music/HoneyWorks' "[[Music/ConfessionExecutiveCommittee Little Lion]" features two magical entities referred to as "The Sun" and "The Moon", who both bless the song's protagonist with a human body on the condition that he never tells a soul that he was originally a cat.

** On ''The Seeds of Love'' [[https://www.blackmagazin.com/wp-content/uploads/2020/10/TFF-Seeds-Of-Love-Cover-.jpg cover art,]] Roland Orzabal's blue suit represents the nighttime and Curt Smith's gold suit represents the daytime. It's a visual metaphor that the two band members are as [[OppositesAttract different]] as [[RedOniBlueOni night and day]], and that they act as {{Foil}}s to each other. This mirrors their astrological signs (Orzabal is an avid follower of the WesternZodiac) because sun-ruled Leos (Orzabal) and moon-ruled Cancerians (Smith) have opposite personalities. [[note]]For instance, when it comes to arguments, Orzabal has stated that he's a shouter (a "lion's roar" is naturally a Leonine trait, as Leos draw strength from the sun's power) whereas Smith admits that he's a sulker (which is to be expected from moody Cancerians, whose emotions vary with the ever-shifting lunar phases).[[/note]] In theory, the duo's astrological association with night and day is supposed to reflect that their contrasting natures compliment and balance each other musically, but in reality, they often fought during the recording process because Orzabal had near-total control over the group at this time, and as a result, Smith's involvement on the album was rather minimal. Their creative differences eventually tore their musical partnership apart because Smith split from the band two years later.

** The duo's astrological link to night and day is revisited in the "[[https://www.dailymotion.com/video/x10otut Closest Thing to Heaven]]" music video (it's the first one which starred both Smith and Orzabal since they revived their musical partnership) which features nighttime and daytime scenes in a play. The two band members perform in the orchestra pit and they provide the soundtrack to the story unfolding on stage, the significance being that a Cancerian and a Leo have finally found a more harmonious way to create music together while still maintaining their disparate personalities.

* ''Manga/KannazukiNoMiko'': Chikane is associated with the Moon, Himeko with the Sun. The symbolism is further explored when Himeko, who believes herself to be an utterly ordinary girl, [[ICantBelieveAGuyLikeYouWouldNoticeMe wonders what the start student and school idol Chikane sees in her]]. Chikane then proceeds that, just like the Moon only shines with the reflected light of the Sun, so is Chikane inspired and motivated to "shine" in all things by her [[GirlsLove relationship]] with Himeko.

* ''VideoGame/PokemonDiamondAndPearl'' has this in the names of the BigBad and the Champion. The former's name is "Cyrus", whose name relates to "sun", while the latter's name is "Cynthia", a name that relates to Artemis, Greek goddess of the moon.

** Espeon and Umbreon were introduced in the second generation to show off the new day/night feature. Both evolve from an Eevee that has high happiness, but Espeon evolves during the day and Umbreon during the night. For further contrast, Espeon is a Psychic-Type, and Umbreon a Dark-Type.
** Lunatone and Solrock are, as their name implies, living stones based on the sun and the moon. They are believed to be meteorites, though this is unproven. Solrock is said to absorb energy from the sun while Lunatone is most powerful during the full moon. Finally, they are version counterparts, with Solrock being in Ruby and Lunatone in Sapphire.

* ''Film/{{Twitches}}'', and its sequel ''T*Witches Too'', has main characters Alex and Cameryn, twin rulers of the fantasy world Coventry. Alex, the misfortunate DeadpanSnarker of the pair, is associated with the night, being active when the moon is up and owning a moon-shaped charm. Bubbly and lucky Cameryn, meanwhile, is represented by the sun. Their birth names are [[Myth/ClassicalMythology Artemis and Apollo,]] respectively.
