I’ve got Norad Santa up and am tracking Santa’s progress across the globe. As far as holiday traditions go, this one is particularly interesting to me as a writer.
Whenever a writer tries to create a fictional culture, (s)he tries to make things believable by envisioning all the consequences to society. One of the ways to gain a real feel is by inventing holidays or traditions that relate to peculiar conditions of your world. If you have two moons, you would have a conjunction day, which might be a celebration of love.
Many science fiction writers of yesteryear envisioned the internet. Did any of them think of this? Future generations will wonder what the holidays were like without it.
