today is tabernash. it's a mormon holiday.
as i understand it, tabernash started when my brother was in high school. a classmate had heard a rumor that mormon's don't celebrate Christmas and, curious but not wanting to show ignorance, asked one of my brother's friends. and, being that my brother ran in circles with too much creative energy, recieved the answer that no, mormons don't celebrate Christmas, but rather, "tabernash." as school was ending for the Christmas break, a student passed my brother and courteously wished him a "happy tabernash."
so it began and so it continues.
the date was randomly chosen to be december 23rd, coincidentally coinciding with joseph smith's birthday. celebration is pretty much whatever you want, though it's customary to sing "it's the mormon tabernash, tabernash tabernash" to the tune of "in the hall of the mountain king."
you can read tim's personal account of it here. it's a slightly clearer (and better) telling of the post above.
it's a takes a bit of searching, but please join the tabernash event on facebook.
as a bonus along those same lines....
