Out Of Season Episode
Holiday episode airs when it's nowhere near the season in-universe in real life.
Seasons happen at different times per year in different parts of the world. Add in the various different Time Zones, and chances are episodes of various different shows can come out at different times per year. This occurs when the episode that airs at a time that is different than the time of year in Real Life. A seasonal variant on (but not entirely related to) Out of Order, and occasionally is caused/causes Short Run in Peru.
- The special Merry Christmas, Drake & Josh was Adored by the Network for a while by Nickelodeon, airing even when it was no longer Christmas.
- In Doctor Who, there's the 1996 TV Movie, intended to be a pilot for the revival of the series. Here, the Doctor went into 1999 New Year's Eve being dead and regenerated from his seventh incarnation to his eighth one. Apart of being exhibed in May, the year wasn't 1999 and even the place isn't Great Britain In-Universe (New York, USA) nor the filmation place (Vancouver, Canada).
- Surviving Christmas, starring Ben Affleck, a movie that takes place during Christmas, was released on October 22, 2004. It originally was slated for a Christmas 2003 release, but it was pushed back to avoid competing with another Ben Affleck film, Paycheck.
- Invoked in an episode of Haven. A Christmas episode, released around Christmas in Real Life but taking place in July in-universe. Someone's trouble was creating Christmas in Haven by trapping the town in a snowglobe, and only Audrey, who is immune to the Troubles, knew something was wrong. Everyone else just assumes she's a Grinch for not liking Christmas (and thinks she's crazy when she says Christmas is not in July).
- Averted with Friends. They don't show any Christmas, Thanksgiving or Halloween episodes unless it's the actual month of those holidays. This actually cause a bit of a continuity problem because two Thanksgiving episodes were plot important; one dealing with Chandler being able to date Joey's ex girlfriend and another having Monica and Chandler being able to adopt.
- Sweet Bro and Hella Jeff does this as part of its Stylistic Suck, deliberately releasing all holiday-specific comics on the wrong day. For example, the Christmas comic going up on May 1, the Halloween comic on December 26... and even a comic that had as punchline "It's Tuesday, you fat nasty trash!" came out on Monday.
- American Dad!:
Roger: Merry Christmas from our family to yours! Wait a minute, is this our Christmas episode? What month is this?
- Parodied in the episode "Gifted me Liberty", aired on June 13, 2016. It begins much like a Christmas Episode but the rest of the episode takes place after Christmas, and ends during Christmas again. Lampshaded by Roger when he breaks the fourth wall at the end:
- The Season 14 premiere, "Father Daze", is treated as a Father's Day episode but the episode aired on November 7, 2016. Within the episode, Stan keep erasing his family's memories everyday until they give him the perfect Father's Day and he's been doing this for six months.
Stan: You know what, guys, this is easily one of my favorite Father's Days. And Christmases. Did you guys know it was Christmas.
- Tiny Toon Adventures: Night Ghoulery was originally intended to premiere in October of 1994, but ended up premiering on Fox on May 28, 1995.
- In the Aqua Teen Hunger Force season 1 episode "Cybernetic Ghost of Christmas Past from the Future", the titular character breaks into Carl's home claiming he's the Ghost of Christmas Past and comes to show Carl what Christmas was like for him in 1968. Carl reminds the Ghost that it's not Christmas at all, but in fact February. Hilariously enough, the episode actually aired four days after Christmas.
- Inverted in Gravity Falls. The episode Summerween aired in October where Halloween is, but In-Universe it's in the middle of the summer. Justified since the people of Gravity Falls like Halloween so much that they celebrate it twice a year.
- For a while The Simpsons would air their "Treehouse of Horror" episodes around the first week of November, which got Lampshaded in later years. Generally averted on syndication, where they are usually only shown on October, although FXX will often include one as part of their themed blocks if it somehow fits the theme.
- Sonic Boom had the episode "New Years Retribution", which aired in August, 2015, four months before New Years 2016.
- While most holiday episodes of SpongeBob SquarePants avert this, one in particular, "Fools in April", airs with its sister episode "Neptune's Spatula" throughout the year, even when it's nowhere near April Fools Day.
- Steven Universe aired the episode "Horror Club", clearly treated like a Halloween Episode, on February 12, 2015. (It has to be noted that, according to Word of God, some festivities don't exist within the show's 'verse, Halloween included).
- As the Adored By The Network page states, the holiday themed episodes of Teen Titans Go! are played even when it's not said holiday. For example, "Thanksgiving" was frequently played in early 2015 due to being paired with "Serious Business", one of the show's most popular episodes, "How 'Bout Some Effort" played even after Valentine's Day passed, and "The True Meaning of Christmas" will often play every two weeks.
- My Little Pony: Friendship Is Magic
- Averted with the fifth season, as many people believe the reason that there was a mid-season hiatus was to air an Halloween Episode close to Halloween.
- Played straight with the season 2 episode "Hearts and Hooves Day", as despite being a Valentine's Day Episode, it is frequently aired outside Valentine's Day.
- The episode "Hearthbreakers" aired one week before Halloween, despite being a Christmas Episode.
- The second Christmas Episode (which is also Yet Another Christmas Carol), "A Hearth's Warming Tail", aired in May.
- Phineas and Ferb: The brothers intentionally had a Christmas episode in mid summer, and televised it in-universe.
- In The Fairly OddParents!, the April Fools' Day episode, "Fools Day Out", premiered on October 11, 2002 and it only had a Halloween moment for a few seconds.
- The Batman: The Animated Series Christmas Episode "Christmas with the Joker" originally aired on November 13, 1992—weeks before the Christmas season even started.
