Santa Claus is coming to Town is playing on the 5th at 8 on ABC.
Rudolf and Frosty are on Friday on CBS at 8 and 9.
The Grinch will be on Saturday at 9 on ABC (Jim Carey version - boo)
Scrooged is on Sunday the 10th at 2:00 on ABC Family.
More will be posted as I spot them (or add to the list as you spot them)
Olive the other Reindeer?
Dec. 14th on the Cartoon Network at 11AM (on the West coast). Probably other times too.
Miracle on 34th st. Dec 3rd (today) on AMC at 8:00 PM
Looks like The Life and Adventures of Santa Claus will only be on three times—on Dec 9 at 11a.m; the 12th at 7pm; and the 24th at 3pm—on ABC family, this year.
It’s from a story by L. Frank Baum, apparently set in the same universe as Oz, though it’s not a crossover. It’s affectionately known as “Hobbit Claus” at my house.
It has a wood sprite with Tourette’s syndrome, and the line “They are training to be Samurai,” which I believe is unparalelled in all of the christmas specials ever made.
And a horned wizard named Ack who slays goblins with a magic axe.
It is not a comedy.
All courtesy of the magic of Rankin-Bass stop motion.
Joe Bob Ranchoth says check it out.
We bought most of these on DVD last year so they’re playing weekly at CasaRuby! 
There’s also a live-action version of The Year Without A Santa Claus on December 11, starring John Goodman as Santa, Delta Burke as Mrs. Claus, Michael McKeen as Cold Miser, and Harvey Fierstein as Heat Miser.
I forgot to note that it’ll be on NBC.
Holy Cow, that has train wreck written all over it. I’m going to have to catch that.
Plus the original, of course (thanks to the OP; that’s probably my favorite).
What about the cartoon Twas the Night Before Christmas*?
I thought so too, but the youtube preview (linked in another post) makes it look fun. I will probably try to remember to watch it.
Shoot, miscoded back there: What about Twas the Night Before Christmas (the cartoon from the 70s)?
Yikes. We’ll see…
However, if this is a TV movie and not just a Christmas special, then that means they’ve padded at least another 1/2-hour’s worth of material and that bodes particularly ill.
Still, I’m sure I’ll watch it (the Mrs. is revving into Xmas mode)
The one with the mice? The IMDB entry doesn’t have any upcoming broadcasts listed.
I didn’t get to see it at all last year! The Life and Adventures of Santa Claus is my all time favorite Rankin-Bass special. For some reason, the idea of Santa having a Mantle of Immortality really made sense to me when I was little.
As mentioned the Year Without a Santa Claus, live action version is on Monday night the 11th. NBC 9 PM
The Life and Adventures of Santa Claus will be on the 12th ABC Family 7 PM
Dr. Suess’ Grinch animated version will be on the 12th, ABC 8 PM

No Charlie Brown Christmas?
Hm… I’m gonna have to find my copy of “The Nightmare Before Christmas”. Maybe watch it along with The Santa Clause.
Already happened. I don’t remember seeing in to ABC Family’s schedule between now and the 25th; I think you only get one shot at it (on CBS, IIRC). Sorry. 
I think they’ve been playing that twice a night for a couple of weeks now with the colorized version at 8:00 (eastern) and the b&w at 10:00 (eastern).
