Calendar of Sci-Fi, Fantasy, and Genre Days

When is Hobbit Day? When is Star Trek Day? and other Days that matter to Sci-Fi and Fantasy Fans.

Most people know of Star Wars Day thanks to the slogan “May The Force Be with You.” If you are a sci-fi and fantasy fan, you might be delighted to know that there’s a full year’s worth of sci-fi and fantasy days that might catch your interest.

It’s a great way to know what book to read or movie to watch this week. Or you could use these dates to plan get togethers with your sci-fi and fantasy friends.

I believe in giving people what they ask for, therefore:

Here some popular dates:

Yoda Star Wars
Yoda of the Star Wars universe, first appeared in the 1980 film The Empire Strikes Back. He is powerful with the Force and served as Grandmaster of the Jedi Order.
May
May 1MerMayMultipleMerMay is a month-long celebration of creativity, community and above all… MERMAIDS
May 2International Harry Potter DayHarry PotterDeclared by (muggle) Prime Minister David Cameron in 2012. Anniversary of the battle of Hogwarts in 1998
May 4Science Fiction DayAnother accepted birthdate of Isaac Asimov (no one is sure whether that's actually the day he was born)
May 4Star Wars DayStar WarsMay-the-fourth be with you
May 4Anniversary of the Battle of New YorkMarvelOne suspects that in-Universe, this is a day more like 9/11 than any sort of celebration. Fortunately, we're not actually in a Universe where a finger-snap could do just about anything. So Avengers fans, this is your day to enjoy some Shwarma and maybe watch a particular movie.
May 6Revenge of the 6thStar WarsMore Star Wars celebration, this time with a sith-twist
May 7Free Comic Book Day*Participating comic-book stores only.
May 9Goku DayDragon Ball ZChosen because 5 and 9 read as Go and Ku in Japanese
May 10Whacking DaySimpsonsSnakes beware
May 13Piccolo DayDragon Ball ZOriginally celebrated on May 9th (see Goku Day), it is believed this day – which celebrates the day that King Piccolo declares his ruling of Earth – was changed to the 13th because the number 9 is considered unlucky in Japan.
May 21National Talk Like Yoda DayStar WarsRelease of "The Empire Strikes Back" this celebrates
May 22World Goth DayYou know who you are, and we're there for you.
May 25Towel DayHHGTTGSomething, something hoopy frood.... Originated as a tribute two-weeks after the death of Douglas Adams in 2001.
May 25Geek Pride DayStar WarsComes with a bill of rights. Celebrated on the anniversary of the release of Star Wars, geeks are just people with a passion about something. Maybe it's food, or cars, or science fantasy films. It's all good. Be proud.
Captain Picard Day
While there is some debate about the date, fans have celebrated Captain Picard Day on June 16th of each year. That date is equivalent to stardate 47457.1, which is mentioned in the episode "The Pegasus".

Alice in Wonderland

July
July 1International Zine MonthCelebrating independent publishers. There are zines for just about every topic, but they have been huge in the science-fiction fantasy realm. The first science fiction zine was published in 1930. Zines (formerly "fanzines") were huge in Star Trek fandom in the '70s. The number of erotic Star Trek fanzines alone is much larger than anyone would expect.

July 4Alice in Wonderland DayAlice in WonderlandLewis Carroll's birthday
July 8National Video Game DayGaming
July 13Embrace your Geekness DayGeekness is having a moment -- and has been for more than a decade now. This brings much joy to the heart of those of us who bore the epithet of "Star Wars Freak," back in the day.

August 12Federation DayStar TrekStar Trek's Independence Day
August 19Gene Roddenberry's BirthdayStar TrekOne can't help but wonder if "Hatching Day" is more appropriate for the Great Bird of the Galaxy. Either way, this is a day to celebrate the father of Star Trek and much more.
August 27International Cosplay DayOr you could turn this around and say that every OTHER day is when you are cosplaying as a normal, responsible member of society, and that Cosplay Day is the time you dress as you really are.

October
October 6National Mad Hatter DayAlice in WonderlandA tea party is the obvious way to celebrate, but when did the Mad Hatter ever do the obvious thing? Still, a tea party is a really good idea for this one.
October 12Hitchhikers Guide to the Galaxy DayHHGTTGDate the first novel was published in 1979
October 15National Costume Swap DayThose old costumes you didn't get rid of on Purge Night (March 21)? You can exchange them with friends to try something new this year.
October 18Jayne DayFireflyRaise one to the Hero of Canton. I'm suggesting beer, wine or a cocktail on this one. That mudder's milk does NOT look appetizing. Maybe a good day to share ill-begoten gains with the downtrodden (or any gains regardless of how they were begotten).
October 21Back to the Future DayBttFThe day Marty and Doc Brown jumped to in 2015, which used to be the future.
October 26Worldwide Howl at the Moon NightHowl at the moon to celebrate the macabre -- and wolves. Do not underestimate the restorative power of a good howl or two. Also do not overestimate the patience of your neighbors.

Introduced in Strange New Worlds as Stardate 1377.3.

April 28Superhero DayMultipleI was always told that every day is "Superhero Day," but I suppose it's prudent to show appreciation for those living among us who can leap tall buildings with a single bound, melt steal with their eyes, call lightning to earth using a hammer, or have so much money they can make a super-powerful suit of iron or such a collection of gadgets, body armor and vehicles that they're virtually invincible.
