Devildom/Dates and Holidays

Every important Devildom date can be found on this page, be it holidays, events, or birthdays! The Devildom Calendar lists every named day of the year as noted in Nightbringer's "What day is it today?" widget.
== Holidays ==
The Devildom has many holidays, including those unique to the world, adopted from the Human World, or with names shared with the Human World, but celebrated very differently.
=== Christmas ===
It is implied in the Pop Quiz Dark Santa that Christmas may not have been widely celebrated in the Devildom before MC's arrival as a RAD exchange student, if it was celebrated before then at all. However, after MC's arrival, Diavolo hosted and organized a party and gift exchange in said Pop Quiz, as well as a holiday event at RAD seen in the Devilgram What Goes Around Comes Around.
After this, Christmas became a fairly popular holiday in the Devildom, as Leviathan stated in the Devilgram A Jealous Christmas. Diavolo also told MC in the Pop Quiz Presenting Perfect Memories that it was due to their influence that Christmas had become "such a beloved event in the Devildom."
Christmas in the Devildom is celebrated in a similar fashion to how it is in the Human World, from exchanging presents, to having dinner parties, and even decorating Christmas trees. Leviathan also mentioned that in the Devildom, the holiday had become "an excuse for couples to act all lovey-dovey in public."
As for Christmas trees, it seems common for demons to import fir trees from the Human World for decorating, as Mammon had an interest in selling fir trees in the Dark Santa Pop Quiz, and Diavolo gifted Lucifer with a fir tree during the holiday season in the Devilgram Christmas Tree. There are also native Devildom pine trees that can be used for Christmas trees, as mentioned in the Pop Quiz Happy ☆ Holidays!.
Santa is widely known in the Devildom to be a real being, unlike being considered a fictional character in the Human World.
=== Halloween ===
Halloween is considered a very important holiday in the Devildom, as it is also a celebration of Diavolo's birthday. Celebrations of this event last for three days.
=== Helldown Day ===
Helldown Day is mentioned in the chats Helldown Day 1, 2, and 3. Helldown Day was created in the Devildom as a way to protect the balance of the three worlds. During the holiday, all demons must refrain from using their magic. The use of magical items is also prohibited.
As Mephistopheles explained in Lesson 73-17 (OM), if magic is detected on Helldown Day, the spell is cancelled by force.
=== Jill's Day ===
This holiday is mentioned in the Devilgram The Rare Flower. According to Lucifer, it is named after a woman who sold her soul to a demon. To celebrate, a tea party is hosted at the Demon Lord's Castle and Diavolo is presented with extravagant gifts.
=== New Years ===
In the Devilgram A Special Ceremony, Lucifer mentioned that New Years celebrations happen every 100 years in the Devildom.
=== Sir Black's Anniversary ===
This holiday is mentioned in the Devilgram The Rare Flower. It takes place in the month after Jill's Day and can also be celebrated with a tea party and gifts.
=== Thanksgiving ===
In the Pop Quiz You're A Gem, it is shown that Thanksgiving in the Devildom is a week-long holiday when magical gemstones intermittently rain from the sky. This happens once every 100 years. Exposure to these gems causes both demons and angels to enter an extremely positive mood, and express what they are thankful for. Giving these gems as gifts to loved ones is customary, and doing so also negates their magical mood effects.
Each colored gemstone has its own unique meaning. See the Geology section for more info.
== Events and Festivals ==
While many Devildom events and festivals have a long history, according to Diavolo in the Pop Quiz Dark Eternal Bliss, the 666th time a festival occurs is cause for lots of extra celebration. The reason behind this isn't stated, though "the number six has quite a number of meanings in the Devildom."
=== A - G ===
==== Comic Séance ====
This event was mentioned in the chats An Invitation to C.S. and The End of Summer, as well as the Devilgrams from Otaku Panic. It is an event that takes place during the summer where attendees can buy or sell indie manga and novels based on their favorite anime and manga. Hundreds of thousands of witches (dead or alive) are chosen by raffle, and then general admission is 8,000,000 spots for demons. 
The event is held in several halls, which are split into block letters and booth numbers. Two of said halls are named "Curse" and "Prison," and Leviathan's booth was located at Curse C 42-A. There are also areas for cosplayers to socialize and take pictures. The event attracts huge crowds and has bad D.D.D. reception, which makes it easy to get swept away or lost if one isn't careful. A shuttle bus is also availible to take atendees to the event.
Comic Séance shares many similarities to Comiket and other doujinshi conventions. Vendors at C.S. refer to themselves as "the circle," a term used by doujinshi artists in Japan.
==== Cow-Herding Festival ====
As explained in the Pop Quiz The Demonic, the Bovine, and the Sheepish, the Cow-Herding Festival is a regularly-held festival where Devildom Cows are herded to a more spacious area to roam free before they approach the season where their behavior turns aggressive. Participants who herd the cows are tasked with caring for and bonding with the cows beforehand. Then on the day of the festival, they herd all the cows to their new location while onlookers enjoy the spectacle. Once the cows are safely moved, a party is held afterwards. There are also special prizes awarded to herder participants, which change from festival to festival. The rewards of one event included extra-large steaks.
==== Crèmeson Festival ====
This event was mentioned in the Devilgrams Everlasting Happiness and A Sweet Promise of Love. It's an event held on Crimson Street, and seems to be based on the real-world event White Day. During this event, there are many activities happening inside and around the cafés on the street, and there are also foodcarts selling sweets. The Festival's mascot is Devil Cream Ellie, who is possibly the elephant pictured in the card art for Everlasting Happiness.
There is also a special bell called the "Eternal Devil Bell" that's set up especially for the Crèmeson Festival event. Rumor has it if a couple shares some sweets together and then ring the bell, the two of them will be "blessed with everlasting love and sweetness."
==== Devildom Film Festival ====
This festival was mentioned in the chat Let's Go to the Film Festival. In this chat, the theme for the upcoming festival was mentioned as "the principles of human behavior."
==== Devil's Run ====
This event was mentioned in the Devilgram Colorful Panic. It is an annual race where runners try to make it to the end of the course as multicolored demon powder, demon gel, demon water, and other things rain down on them. It was mentioned that demon water causes hallucinations if it gets in one's eyes. The Devil Run staff use magic to control the gel and powder, so they can target whoever they want to. They can also choose not to target Diavolo or Lucifer due to their ranking, even though Lucifer told them in the Devilgram that it didn't matter.
==== FangoBurger Fest ====
This event was described by Beelzebub in Lesson 60-A (NB) as "the event that combines Fangol and hamburgers into one epic celebration!" Atendees can watch Fangol games and cheer on teams such as the Steel Falcons. There are many Fangol-themed foods availible for purchase, such as fango-cheeseburgers, havoc fries, tornado pie, steelmuffins, falcon nuggets, and the shark pancake mega-stack. 
==== Fangol Ultra Bowl ====
As described in the Pop Quiz The Fangol Ultra Bowl, The Fangol Ultra Bowl is a massively popular yearly sporting event that determines the Fangol league champions. Merch is sold in town leading up to the Ultra Bowl, and many fans begin preparing several weeks in advance to properly celebrate. RAD once hosted a special screening of the Ultra Bowl between the Destroyer Sharks and the Steel Falcons.
The players swear the Player's Oath on the Glorious Devil Ball, a golden decoration belonging to the Fangol Association that symbolizes the Ultra Bowl. The Glorious Devil Ball has a mind of its own, as it is a physical manifestation of the ideals of Fangol: unity, togetherness, and reaching new heights.
==== Festival of Eternal Bliss ====
As described in the Pop Quiz Dark Eternal Bliss, this festival was once a Devildom custom that had the local ruler "wed under cover of darkness" in a festive ceremony. The details are vague, but someone powerful - possibly either a warrior or sorcerer from the Devildom - was once selected to marry the lordly demon. Instead, this selected person opened a gate to another dimension, and banished the lord there. The festival then continued to happen in this other world.
In this festival, the chosen marriage partner would ride the "Flaming Spirit Chariot" to the lord of the festival. It is possible to create a doll to take the place of the selected marriage partner, but in past festivals where this was done, it offended the lord, and the celebration failed. According to an old book, the marriage partner was chosen by the lord, and this was done by having a birthmark appear on the back of their hand.
==== Frost Flower Festival ====
As seen in the Pop Quiz Absolute Zero, this festival is held every 300 years, and is both a large-scale carnival and an important ceremonial event. During the festival, denizens of the Devildom pray for a bountiful harvest and ask the divine white wolf of frost flowers to continue providing good weather to the Devildom. Each time, someone is chosen to be the symbolic representative of the festival, and in the past both Diavolo and Barbatos have taken this role. This person's primary duty is to both enjoy and pray for the success of the festival.
Some festival organizers are also tasked with fasting for at least four days during preparations as a symbolic means of praying that the Devildom's citizens won't struggle to find food in the future. Those who are fasting are given magic bottles of air, and breathing the air provides them with the nutrients needed to survive.
During the festival, the Devildom is decorated with ice sculptures and flower arrangements, including the official festival flower called the Permafrost Camellia. There is also a carnival dance similar to a waltz, and a large parade.
==== Ghost Festival ====
The Ghost Festival is held in the Devildom on occasion for the spirits of the dead, and the date that it's held is always decided at the last minute. In this festival, ghosts decorate the town with neon colored skulls and candles. Once preparations are complete, ghosts wear painted skulls and parade down a candle-lit path, which only ghosts are permitted to walk. According to Lucifer in the Devilgram Wish Upon a Soul Flower, this is because the colorful candles "represent a path for the deceased."
It was also mentioned in said Devilgram that demons aren't fully aware of the true meaning behind the parade, but some demons do assist with the festival's preparations. Non-ghosts can also participate through song or musical performances, and there are many food stalls set up during the festival.
The festival also involves orange flowers known as soul flowers, which are thrown at ghosts at the end of the parade, who then are said to grant wishes in return. The flowers wither in a day, but when they do, particles of light can be seen floating into the sky. This fading light marks the end of the Ghost Festival.
According to Asmodeus in the chat A Ghost Festival Party!, a special, limited-edition soul flower-inspired color of cosmetic is sold every year at this festival. According to Beelzebub in the same chat, special foods are also available at the festival. He describes one particular item as being thin pieces of bread wrapped around meat and veggie fillings.

==== Hell Demon Salmon Festival ====
This festival was mentioned in the Pop Quiz Hell Marine Festival. Mammon read about this festival in The Encyclopedia of Sea Festivals and Traditions, and noted that Beelzebub would love such a festival. 
==== Hell Marine Festival ====
An annual, multi-day, music festival, as seen in Pop Quiz Hell Marine Festival, where anyone is welcome to sign up with an original song matching that year's theme to perform for the Devildom. One year's theme for the first day was "Scream Your Love at Hell Marine ♡", with the second day's theme being "Hell Marine ♡ Lovey-Dovey Scream", according to the Devilgram Legendary Power Couple. The third day's theme for that year was "Hell Marine ☆ Summer Melodies", according to the Devilgram The Power of a Fan.
The festival originated from the "Siren's Sonnets". These sonnets must contain only the truth, a law which has been passed down to include the songs that are performed at the Hell Marine Festival. 
==== Hellfire Incineration Festival ====
During the yearly Hellfire Incineration Festival, a huge bonfire is created in the center of town by fire spirits from all over the Devildom, as seen in the Pop Quiz The Cursed Seed and the Fertilizing Flame. This bonfire allows people to bring any cursed objects or powerful magic items and safely dispose of them by burning them.
If someone wants to preserve their possessions, the festival offers paper talismans with seals on them designed to transfer any curses or enchantments attached to said possession and seal it within the paper. Whether it's items or talismans that are burned, the physical objects will turn to ash, but the magic remains and is eaten by the fire spirits that keep the fire burning.
There are also things like specialty shops and stands, food stalls, and entertainment provided by a traditional instrumental band at this festival. The festival is alluded to changing the location it's held yearly, as Solomon made a comment that it was "being held in Moryo Town this year."
The Hellfire Incineration Festival has an official website as well as a mascot character, and said mascot was designed by the same artist that did the character design for Ruri-chan's arch nemesis.
==== Human World Fair ====
This event was mentioned in the phone calls Human World Fair 1 & 2 from Barbatos. It is a popular event in the Devildom, and the venue is often very crowded. Curiosities and delicacies from the Human World are gathered there to be exhibited and sold, and it is possible to acquire rare commodities. One of the stalls is called "Bizarre Foods."
==== Hyakki Yako ====
Also known as "The Night Parade of 100 Demons" or The Great Yokai Parade, this festival takes place in Moryo Town. During the festival, demons participate in the ritual of lighting outdoor lanterns in front of all the houses while dressed up as yokai. According to Beelzebub in the Devilgram Go Beelzebub! Transform!, at least some yokai costumes not only give demons the appearance of yokai, but some of their powers as well. When in his Bake-danuki costume, Beelzebub is able to transform himself into other objects.
Lighting a house lantern gives whoever lives there a good year, and the "yokai" that lights the lantern gets to make a wish that supposedly comes true. The color of flames for a lit lantern varies depending on the type of lantern, and each color symbolizes something. A lantern with red flames means that whoever lives in the house owning the lantern will meet someone special. Yellow flames mean that the home's residents will end up with lots of money.
During the festival, there is an event where participants have to light a lantern deep inside a cave. Whoever manages to do this wins a prize of some sort. It is rumored that taking part in the event could involve encountering a real yokai.
Hyakki Yako is a long festival, and lasts until the last lit lantern goes out.
==== Limited Edition Market ====
As explained in the Devilgram Flea Market Love Stories, this market event comes around only every few decades, and many different businesses participate in it. Items are sold at this market that can't be bought anywhere else, such as rare books, food, and art. The main sponsor for the market is a friend of Diavolo's.
==== Queen Rose's Banquet ====
This event is held annually, as mentioned in the Like a Dame Pop Quiz. Every year, Queen Rose is received at the Demon Lord's Castle and a formal banquet is hosted to celebrate. As a rule, Diavolo and his co-host must dress up as women when interacting with her. The person chosen for this honorable role is called the Dame and traditionally, Lucifer has fulfilled this role. The event is also highly exclusive as the only people allowed to approach the Queen are Diavolo and the Dame (i.e. the rest of the brothers were not allowed to attend).
==== Slice of the Human World ====
This event was mentioned in the chat An Especially Smelly Gift. Part of the event involves Human World food. For example, the brothers find a leftover can of what is presumably surströmming, a lightly-salted fermented Baltic Sea herring traditional to Swedish cuisine.
