Horror Doesn't Settle for Simple Tuesday



" February 29. Superstition has it that if you are a teenager and have sex on this day, you will be macheted to death by a maniac wearing a makeshift mask made out of a calendar. This superstition is, of course, the basis for the '80s horror movie Leap Year."

- More Information Than You Require

It goes like this: You and your friends are having a nice Easter party, when suddenly a deranged killer in a bunny mask starts stalking you. On April Fools Day, that guy you and your friends pulled a rather nasty prank upon is out to get you. On Halloween, the dead rise from their graves and start to terrorize the neighborhood. And on Christmas, The Antichrist decides to be born.

"Oh for Pete's sake!" you exclaim; "Couldn't these things happen on any other day, like, Tuesday?"

Sorry pal, Horror Doesn't Settle for Simple Tuesday.

When the horror happens, it tends to happen on Holidays and other special days marked on your calendar for various reasons: Lots of people tend to gather around on those days, usually at a remote location, calendar days make nice titles and nothing quite says Subverted Innocence than, for example, Santa Claus killing people with an axe.

Also, remember, some days are sacred to pagan/occult religions and so "natural" choices for supernatural events. These days may have had Christian and/or commercial holidays added, or they may just be special to the pagans/witches/satanists/whoever, still not just Tuesday, even if the hero doesn't know this at first.

And of course, Lovecraftian unspeakable horrors don't have any use for the human calendar, so they won't bother to do the timezone math to see where to appear. They only care the stars are right on THEIR calendars and none of these calendars have Tuesday!

Popular trope among Horror movies (especially in Slasher Movies), but not necessarily limited to them.

Multiple

 * Stephen King's Cycle of the Werewolf, where the moon is conveniently full for a couple of holidays (New Year's Day, Valentine's Day, St. Patrick's Day, April Fool's Day, Homecoming Sunday, high school graduation, the Fourth of July, Labor Day, Halloween, and New Year's Eve).
 * The Hack Slash comic Entry Wound had every holiday-related slasher "waking up" early due to a cosmic disturbance. While various holiday slashers are alluded to, the main villain of the story was a Groundhog Day-based one (if the groundhog sees his shadow, six weeks of death ensue).
 * The Enfant Terrible film Home Movie has sequences set on a number of different holidays; in order, they're a birthday, Halloween, an anniversary, Thanksgiving, Christmas, New Year's Eve, Valentine's Day and Easter, which the climax occurs on.
 * Fearnet has produced a series of shorts featuring Sam from Trick 'r Treat celebrating a variety of different holidays, like Easter and Father's Day.
 * The Horror Seasons is an anthology that features Christmas ("Satan Claws"); Halloween ("The Darkest Secret") and Easter ("Easter Beast").
 * The Long Halloween: The Holiday Killer strikes on Halloween, Thanksgiving, Christmas, New Year's, Valentine's Day, St. Patrick's Day, Mother's Day, Father's Day, Independence Day, a birthday, then Halloween again. On April Fool's it's subverted by the killer himself.
 * Calendar Man has a similar obssession with dates but his crimes tend to be far less impressive. Usually
 * Tales from the Grave, Volume 2: Happy Holidays is a horror anthology with all the segments dealing with holidays.
 * In Real Life, terrorists are far more likely to align their crimes with specific calendar dates than are serial killers, as the former sometimes schedule their attacks to make a political statement, while the latter are usually opportunists.
 * An exception would be the unidentified perpetrator of the so-called Astrological murders; his(?) killings always coincided with something like an equinox, a solstice, or a Friday the 13th.

Other

Spoofs and Parodies

 * Grindhouse XXX had a fake (and surprisingly sex free) trailer for Easter.
 * Mad Magazine spoofed the concept with Arbor Day, which became Hilarious in Hindsight with the creation of the aforementioned Arbor Daze.
 * Arbor Day is again the chosen day of horror when It's A Living took on slasher films.
 * Spoofed in More Information Than You Require with the imaginary slasher Leap Year.
 * The horror anthology NightThirst had a story called "Christmas in July", which had a murderous Santa inexplicably killing in the middle of summer.
 * The Psych episode "Tuesday the 17th" spoofs this trope by having a very Friday the 13 th-esque story (hence the title) happen on an unimportant day.
 * Saturday the 14th also parodies this trope.
 * Along with ending on the prom, the aforementioned Student Bodies begins with a nonsensical series of title cards that inform us that it is Halloween, Friday the 13th, and Jamie Lee Curtis's birthday.
 * Inverted and parodied in Eerie Cuties. Nina supposedly craves chocolate instead of blood because she was born on Easter. Several characters express bewilderment at how nonsensically this sounds.
