Sadly, there is no celebrations in any branch of satanism. Pagans have some, but beside solstices and equinox, i don't see the point of worshiping a reconstructed religion like wicca or other sects like that. I could burn some churches but i'm a coward, so... Maybe i'll sacrifice a tapir ?
Unlike the rest of you, I am religious, and I'm too lazy to do any celebrating. I usually just do what my parents make me do and enjoy the crepes and ice cream for breakfast. Forced family interaction can be depressing though.
