Meaningful Release Date

Go To

"You are PSYCHED about this SPECIAL DATE, 11.11.11 ... a date exhibiting just the sort of numerical gimmick corporations love to exploit for their big releases, or for launching MAJOR REBRANDING INITIATIVES."

This is when some movie, game, TV show, etc., comes out and its release date has some referential meaning related to said media being released. This is usually simply gimmicky, though the date may be relevant to the plot.

Horror movies particularly like to come out on Friday the 13th, as it's an unlucky date, but then, any holiday is a good time for a horror movie.

Remember, there's more than one way to write a date - day/month/year, month/day/year, and year/month/day are all common. Many examples here will seem nonsensical across the pond.

    Anime and Manga 
  • The anime of the books Fate/Zero is rather infamous for a release schedule wherein certain episodes would air on holidays that made them tragically ironic. For example, Mother's Day aired the episode where Kiritsugu blow up a plane with his adoptive mother on it, while the episode where Kiritsugu kills Grail-created incarnations of his wife and daughter aired on Father's day. Word of God says that these (along with the episode where Rider dies airing on the anniversary of his historical incarnation's death) were coincidence.
  • Whether or not it was intentional, following the delays caused by the Tohoku earthquake, the finale of Puella Magi Madoka Magica almost showed on the week of April 30/May 1st, the actual day of the Walpurgis Night; the name of the Final Boss. Instead, it was bumped forwards to Good Friday 2011 (April 21), the day celebrating Jesus sacrificing himself for the sins of mankind. Many viewers saw correlations with the plot.

This date as "Odaiba Memorial" is mentioned several times throughout that show and 02. In real life, it's practically a holiday for the fandom and the stars of the franchise, even using 8/1/2014 to announce Digimon Adventure tri..

  • The first chapter of the manga version of AKIRA came out on December 6, 1982, which is the date of the apparent nuclear explosion that destroyed Tokyo and issued the start of World War III in the story. When the film version came out a few years later, the date of the explosion that destroyed Tokyo was changed to July 16, 1988, the same day the film was first released in Japan.
  • The final chapter of the Rom Com manga My Monster Secret was published on Valentine's Day 2017.

  • The delayed viewing of the third Love Live! Sunshine!! concert, Wonderful Stories, premiered in some countries on June 30, 2018, the date of the eighth anniversary of the Love Live! franchise.
  • Whether by chance or on purpose, both seasons of the Ace Attorney anime have this to a degree- Season One aired in 2016, the year the first game takes place, while Season 2 (covering the third game) is slated for release in October of 2018, which is when "The Stolen Turnabout" (the first case in the third game where Phoenix is the lawyer and that isn't a flashback) takes place.

    Comic Books 
  • A Superman graphic novel titled End of the Century, featuring a massive conflict involving Lex Luthor and the title character, was about and was released as close to the last week of December 1999 as possible. An unrelated story in the regular Superman comics around the same time was the Y2K arc, which also took place on that day and starred Superman and Lex Luthor.
  • Uncanny X Men #137's official street date of September 1, 1980 became this in retrospect, when it was revealed in a later issue that the events of that issue occurred on that very day.

    • Issue #4 was released on June 21, 2017, which happened to be the 11th anniversary of Kate Kane's first appearance.

  • Issue 1 of Doomsday Clock was released officially at around 11:57 pm, November 21, 2017. This was intentionally doubly-meaningful, with the 11:57 evoking the Doomsday Clock trope (released at three minutes to midnight, geddit?) and November 22 being the day that the story opens on.

    Fan Works 
  • The author of Angel Of The Bat originally wanted to post the final battle on Christmas, 2014, as the event itself was set on Christmas Eve. As it became clear this was undoable with any quality left in place and the death of the author's dog took its toll, this idea was abandoned. The fic ultimately received its final non-epilogue chapter on March 17, 2015, exactly one year after it began. Later, a second, ambiguously canon epilogue was added on June 26th, the day the US Supreme Court ruled bans on same-sex marriage unconstitutional. In the chapter, hero Cassandra Cain asks her girlfriend Sadie to marry her.
  • Never Hike Alone, a Friday the 13th fan film, was released Friday, October 13th 2017.

  • Numerous horror movies tend to be released on Friday the 13th, particularly Dracula (1931) and, of course, the Friday the 13th movies. They also aim for October releases especially near All Hallows' Eve because Horror Doesn't Settle for Simple Tuesday (namely the Halloween movies), and also because people are in the market for scary movies during that month.

    • Independence Day: Resurgence, soft released on June 22nd, 2016, not only marks the 20th anniversary of the first movie, but it's also an in-universe plot point as the characters commemorate the 20 years from "The War of 1996".

  • Spider-Man films:
  • Star Trek
  • Star Wars:
    • Ever since Star Wars: Episode IV – A New Hope opened in theatres in May 25, 1977, each subsequent film in both the original and prequel trilogies were scheduled for a May release and were released precisely 3 years apart.
    • The sequel trilogy and anthology films seem to break the unofficial tradition of May releases for December: The Force Awakens premiered in December 2015, while Rogue One opened in December 2016 almost a year to day of The Force Awakens. The Last Jedi was originally scheduled to open one day after the 40th anniversary of A New Hope in 2017 before Disney postponed it to December.

  • One of the hints that George Orwell's Nineteen Eighty-Four is an allegory for contemporary politics is that its title is an altered version of the year of its writing — 1948.
  • Subverted for Harry Potter and the Deathly Hallows; it was originally intended to release on 7/7/2007 (as seven is a number often associated with magic and it was the seventh and last book), but it would have fallen on the second anniversary of the July 7th terrorist bombings in London, so it was changed to 7/21 instead.

  • In the fifth series of the revived Doctor Who, the date in which the universe was scheduled to blow up was June 26th 2010, the air date of season finale "The Big Bang". April 22, 2011 at 5:02pm was the date the Doctor was scheduled to die in the sixth series. Accounting for Lake Silencio timezones vs. British timezones, this means that he appeared to die the day "The Impossible Astronaut" aired.

  • Poirot:
    • The first episode of the third season, The Mysterious Affair at Styles, first aired in the United Kingdom on a Sunday, September 16, 1990. This was to coincide with the celebration of the centenary of the birth of Agatha Christie (September 15, 1890, which is pretty close enough).
    • The first episode of Season 6, Hercule Poirot's Christmas, aired on Christmas Day 1994 in the UK. And the second episode of Season 12, Hallowe'en Party, aired just four days before Halloween 2010.
  • An unintentional example and an unintentional aversion for the 2015 Super Sentai series Shuriken Sentai Ninninger, which had its entire schedule delayed by one week, due to episode 46 of the previous series being preempted by the death of a Japanese journalist at the hands of ISIL extremists: Episode 1 ended up debuting on February 22, also known as Ninja Day, since the number 2 in Japanese sounds like "ni," or "nin-nin-nin", while Episode 7, which celebrated the 40th year of Super Sentai with two special guest stars, was supposed to air on April 5 – 40 years to the day that Himitsu Sentai Goranger premiered - but had to air on April 12th in the end.

  • Whereas Marvel's Netflix shows have normally always dropped on Fridays, the second season of Jessica Jones (2015) will premiere on March 8, 2018 (a Thursday), as that is International Women's Day.

Case in point: all thirteen episodes of season 2 are directed by women, and the main cast is primarily female.

  • The remastered albums of The Beatles were released on 09/09/09, based on the infamous "lyrics" to "Revolution 9". Sgt. Pepper's Lonely Hearts Club Band was released worldwide on CD on 1 June 1987, so that it would indeed be "twenty years ago today."
  • Pink Floyd guitarist David Gilmour deliberately released his latest solo album, On An Island, a rumination on family life, aging, and mortality, on March 6th, 2006, the date of his 60th birthday.

  • On January 8, 2013, David Bowie turned 66 years old — and shocked the world by having his official website relaunched, announcing the forthcoming release of his first studio album in nearly ten years, and releasing the first single and video ("Where Are We Now?") from it. No one in his fanbase or the press (who were sure he'd retired years ago) saw this coming, as he swore his collaborators to secrecy. Three years later, Bowie released Blackstar on his 69th birthday - which turned out to be two days before his death. A year after that, the EP No Plan is issued on what would have been his 70th birthday.

    Video Games 
  • Sonic the Hedgehog:
    • The demo for Sonic Generations was made available on June 23, 2011, exactly 20 years after the first game was released. This is fitting, as it's a game about Sonic's history.
    • Generations's second demo was released on the 17th anniversary of Sonic & Knuckles on October 19. Later, for the Steam Summer Sale of 2012, Generations was discounted to $10.19.
    • Sonic 2 was released on November 24th, 1992, which was a Tuesday. Sonic Adventure 2 was also released on a Tuesday. Not only is it a pun, Tuesday is the second day of the week if you consider Sunday the 7th.
  • The English patch for Yousei Daisensou (Fairy Wars) was released on September 9. The game stars Cirno, who has a memetic association with the number 9.
  • Much like the above-mentioned 9 and Beatles remasters examples, The Beatles: Rock Band saw release on 09/09/09.
  • Nights: Journey of Dream was announced on April 1st, 2007 and released in December of the same year. The original Nights into Dreams had a Christmas version known for having special events occur on Christmas Eve and April Fools' Day.

  • All but onenote  of the God of War Series have been released in March, the month named for the Roman God of War, Mars. In addition, God of War III was released March 16. This may be a reference to John 3:16 in the Bible, as the series has some possible Christian overtones, III most of all.
  • The DS Horror Game Dementium: The Ward was released 31.10.07, or Halloween. This date comes up a few times in-game, such as the combination to a keypad.
  • Call of Duty: Modern Warfare 2 came out on November 10th, 2009, and the launch trailers ended with "11-10-09" blinking on in sequence like the countdown before an explosion. Presumably, this was meant to signify the "exploding" international tensions in the game's plot which results in America being invaded, or just the ramped-up action in the game.
  • Metal Gear Solid 2: Sons of Liberty was released during the Chinese Year of the Snake. Whether this was deliberate or coincidental, at least one trailer pointed it out.
  • Similar to above, Spyro: Year of the Dragon was released in 2000. As it says in the title, the Chinese Year of the Dragon.
  • The myth arc of Assassin's Creed heavily tied into the supposed apocalypse date of 12/21/2012. Assassin's Creed III was released on the same day it begins in game (30.10.2012) to play into this. The game itself ends on the former date.

  • The release date of Super Mario Maker, a game celebrating the 30th Anniversary of Super Mario Bros., was the closest Friday to the September 13th release date of the original game. In an unfortunate coincidence, that Friday happened to be September 11th.
  • World War II Online was released on June 6 to coincide with D-Day. A spectacular example of Tropes Are Not Good, the marketing department forced this as a publicity stunt, despite the game still needing months of work. To say it was an Obvious Beta doesn't even begin to describe its launch problems.
  • Persona 5, a game with a major visual motif in the form of hearts and a theme of "stealing hearts", was set to release in the Americas and Europe on Valentine's Day 2017, before delays pushed the release back to the no-longer meaningful April 4.
  • Tyranny, a game set in a world where the Evil has finally won, released the day after the results of the 2016 US Presidential Elections had been announced. The fact that the release date was announced when the elections' outcome could not be predicted with any certainty may have been a statement in itself.
  • Mass Effect: Andromeda, a game about a space journey to the eponymous galaxy, was released on March 21, 2017 in North America. If this date is written in the date format customary in the US, it becomes 3/21 — or "three-two-one", the iconic countdown preceding most Real Life spacecraft launches.
  • Episode 5 of the time-travel adventure game Life Is Strange was released the day before "Back to the Future Day" (October 21, 2015), the date Marty McFly travels to in Back to the Future Part II.

  • Startopia was released in 2001. in a game of sci-fi Shout-Outs, 2001: A Space Odyssey is one of the main ones with the game's intro and your Virtual Artificial Lifeform who vaguely remembers one of his previous charges being Dave.
  • DOOM (2016) was released on Friday, 05/13/16.
  • Pokémon Omega Ruby and Alpha Sapphire was released on November 21st, 2014, exactly twelve years after the Japanese release of the original Ruby and Sapphire.
  • Brütal Legend was released on Friday the 13th of Rocktober 2009, in order to emphasize how metal the game is.

    Visual Novels 

  • Homestuck has an interesting history of turning release dates into Arc Numbers, and then turning those same arc numbers into future release dates.
    • Andrew Hussie planned to start the comic on April 10, but unexpected delays pushed the date back to April 13, or 4/13. Subsequently, the number 413 pops up many places in Homestuck. And some major flash animations were posted on subsequent 4/13 anniversaries, or on the 413th day since the start of the comic.
    • The Hivebent arc, which introduced the troll universe, began on June 12 (or 6/12), introducing the arc number 612. The flash "John: Rise Up" was released on the 612th day since the start of the comic.
    • Later, the comic introduced another arc number, 1025 (the sum of 413 and 612), generally used to represent some union between the kids' and the trolls' universes. The end-of-Act 5 animation (in which the kids and the trolls escape the simultaneous destruction of both universes) was initially meant to go up in August or September, but significant delays pushed it back until October. Hussie then delayed it a few days longer, so it could go up on October 25 (10/25).
    • Act 6 began on November 11, 2011, so Hussie lampshaded it by making it an in-universe meaningful release date, referred to as "2x3prong Day (whatever that means)". Not surprisingly, Act 6 introduces a new Arc Number based around eleven, or sometimes three ones (1/11), four ones (11/11), or six ones (11/11/11), more commonly the latter.
    • Homestuck also does the variation where the events of certain updates correlate with the days on which they were released. For example, an update showing a ball-shaped object falling from the top of a building was posted on New Years, and another series of updates consisting mostly of Dave making Freudian Slips when talking about a teenage version of his mom was posted on Mother's Day.
  • Roommates has this in spades mostly with the ending pages of the arcs but sometimes with the first ones too. Also not only holidays but solstices are important in this comic, mostly when the fae are concerned.
    • The 2013 summer arc begins on the 21th of June; Summer Solstice / Midsummer - It's about Kings and/or Fae.
    • Halloween arcs routinely begin or end on Halloween.
    • There was also a page titled Gift published on Christmas Eve for example (the second to last page of the 2012 Halloween arc incidentally, the page before it was on Winter Solstice and the last page of the arc on New Year's Eve).
  • Nebula, which revolves around Anthropomorphic Personifications of the solar system, released comic #14 on the blog (it had been available earlier as part of the Nebula Ultra compilation) on the date of the New Horizons flyby of Pluto- July 14th, 2015.
