as a fairy our main holiday this time of year is the Solstice (Yule in the N. hemisphere, Midsummer where I am) but fairies love to celebrate any holiday, or any day at all, really. My favorite all time Christmas movie has to be Elf, or any of The Santa Clause movies.
(Fairies are related to Santa you know, though the Elves claim that distinction you can't necessarily believe everything an elf tells you, they are very elf-centered.)
