Christmas

Christmas was a traditional holiday celebrated by humans around the Earth in the month of December. (TV: The End of Time) Immediately preceded by Christmas Eve on 24 December, (TV: The Unquiet Dead) came Christmas Day on 25 December. (TV: Voyage of the Damned) Christmas Day was immediately followed by Boxing Day on 26 December. (AUDIO: Castle of Fear) Soon after, as noted in the Christmas carol "We Wish You a Merry Christmas", came the New Year. (TV: A Girl's Best Friend)

In the early 21st century, the Earth usually endured an alien incursion around Christmas time. (PROSE: The Forgotten Son original opening) Christmas was associated with the Winter solstice (AUDIO: Mighty and Despair) and beyond Earth, became the "Crystal Feast". (TV: A Christmas Carol) A "Christmas spirit" was associated with Christmas. (TV: The Runaway Bride) People often got together at Christmas, which Danny (in Clara's crab-induced dream) said was because every time they did, it might be the last time. (TV: Last Christmas)

According to Lord President Rassilon of Gallifrey, Christmas during the early 21st century was a pagan rite to banish the cold and the dark. (TV: The End of Time) Christmas came to spread throughout the universe, though the exact way cultures celebrated the holiday varied greatly. As the Eleventh Doctor noted to Davros, the word "Christmas", like the word "father", could mean many different things, whereas words like "Dalek" only had one meaning. (PROSE: Father of the Daleks)

Origin
Christmas commemorated the birth of Earth religious leader Jesus Christ. (TV: Voyage of the Damned) The Eighth Doctor claimed to be present at the event, labelled as the "first Christmas". Since the actual date was not 25 December, he worked the date out from census records in Rome; it was "round about 0|zero BC, AD", in Bethlehem, Judea. He checked all the inns of the town; all of them were packed out, but one at the far end of the town, with a stable attached. He travelled there with Leonardo da Vinci, who didn't dare to go further. (AUDIO: Relative Dimensions) Nonetheless, the Tenth Doctor once claimed it was he who got the last room at the inn. (TV: Voyage of the Damned)

Santa Claus
The figure of Father Christmas (also known as Santa Claus, Pere Noel, Jeff, etc), a man who delivered Christmas presents to young children, became a key part of Christmas. He met the Doctor on multiple occasions. (COMIC: A Christmas Story, PROSE: The Man Who (Nearly) Killed Christmas, TV: A Christmas Carol, Last Christmas)

Activities
On Earth, Christmas activities included parties, (TV: The Girl Who Died) parades (TV: Rosa) and pantomimes. (PROSE: Timewyrm: Revelation, No Future) Christmas decorations included Christmas lights, (COMIC: The Heralds of Destruction, PROSE: Frontier Worlds) Christmas stars, (TV: Turn Left) and baubles (GAME: The Christmas Trap) and were planted on objects such as Christmas trees. (TV: The Doctor, the Widow and the Wardrobe)

Christmas lists were written lists of gifts that one would like to receive for Christmas, usually written by children. (PROSE: Loose Wire, TV: Dinosaurs on a Spaceship) As well as Christmas presents, people received Christmas cards. (TV: Last Christmas)

In workplaces, colleagues known as "Secret Santas" gave each other gifts. (TV: Kill the Moon)

Christmas carols were songs sung by carol singers. They included "Deck the Halls", "O Come, All Ye Faithful", "God Rest You Merry, Gentlemen", "Silent Night", (PROSE: The Gift) "The Coventry Carol", "The Boar's Head Carol", (PROSE: Mirth, or Walking Spirits) "Ding Dong Merrily on High", (TV: A Christmas Carol) "Hark the Herald Angels Sing" (TV: The Unquiet Dead) and "The Twelve Days of Christmas". (PROSE: The Sommerton Fetch)

Christmas dinner, which traditionally featured a turkey, was eaten on Christmas Day. During this dinner, Christmas crackers were pulled, containing Christmas hats and jokes, while "classy" crackers contained poems. (TV: Children in Need Special, The Christmas Invasion, The Time of the Doctor)

During her reign, Queen Elizabeth II made annual Christmas speeches on Christmas Day. (TV: The Christmas Invasion) The Snowman was a television special that was repeated on Earth around Christmas. It featured a snowman that flew around and danced with Father Christmas. (PROSE: The Doctor on My Shoulder)

Greetings
The greetings and farewells traditionally used during the Christmas season were "merry Christmas" (TV: A Girl's Best Friend, The Unquiet Dead, The Christmas Invasion, The Runaway Bride, Voyage of the Damned, Turn Left, The Next Doctor, The End of Time, A Christmas Carol, The Doctor, the Widow and the Wardrobe, The Power of Three, The Great Detective, The Snowmen, The Time of the Doctor, Last Christmas, The Husbands of River Song, The Return of Doctor Mysterio, Twice Upon a Time) and "happy Christmas". (TV: "The Feast of Steven", Voyage of the Damned, The End of Time, The Time of the Doctor, The Husbands of River Song, AUDIO: The Demon of Paris)

Another greeting was "season's greetings". (TV: The End of Time)

Earthonomics myths
In the 2000s, the Sto guide and supposed "Earthonomics" expert Copper knew a distorted version of the festivity, according to which human beings worshipped "the great god Santa, a creature with fearsome claws, and his wife Mary, and every Christmas Eve, the people of UK [went] to war with the country of Turkey. They then [ate] the Turkey people for Christmas dinner like savages". (TV: Voyage of the Damned)

The Doctor and Christmas
Although they were an alien, the Doctor developed a fondness and appreciation for Christmas, celebrating it since they were a boy on Gallifrey. (PROSE: The Celestial Toyshop) The Doctor attempted to enjoy the holiday on several occasions, though they were commonly forced to deal with a threat of some kind. (TV: The Christmas Invasion, The Runaway Bride, Voyage of the Damned, The Next Doctor, A Christmas Carol, The Doctor, the Widow and the Wardrobe, The Snowmen, Last Christmas) The Tenth Doctor once admitted "All my Christmases are like this." (TV: Voyage of the Damned) By his twelfth incarnation, the Doctor admitted to Clara Oswald that all these occasions had soured his opinion of the holiday. (COMIC: Relative Dimensions) The Thirteenth Doctor also admitted to not being too keen on Christmas for similar reasons, saying that she preferred New Year instead. (PROSE: Scary Christmas and Unhappy New Year)

Indeed, Earth — and, specifically the vicinity of London — experienced major events involving aliens at or around Christmas Day, mostly during the early 21st century. (TV: The Christmas Invasion, The Runaway Bride, Voyage of the Damned, The End of Time, The Next Doctor, The Snowmen, The Unquiet Dead, The Return of Doctor Mysterio)

(COMIC: Wait Until Morning) Amy and Rory celebrated various Christmasses throughout their married life in the 2010s. For at least two Christmasses after he dropped them off in 2012, they set a place at the Christmas dinner table for the Eleventh Doctor in the hopes that he would turn up.

(TV: A Christmas Carol) Colonists of the planet Mendorax Dellora still celebrated Christmas in the year 5343. (TV: The Husbands of River Song) The Eleventh Doctor suspected that this eventually resulted in other species adopting the rituals of the holiday noting to Davros that the word "Christmas" had taken on a variety of meanings across the cosmos. Unable to grasp the deeper meaning, Davros compared Christmas to a pathogen, one carried in the hearts and minds of those infected. (PROSE: Father of the Daleks)
