After Thanksgiving, it is officially socially acceptable to start listening to holiday music and watching Christmas movies, specifically old-school cartoons that come out only once a year. 

Freeform released its annual 25 Days of Christmas schedule earlier this month, and now it's almost upon us. Get out your advent calendars and Christmas planners, and mark down these days to watch the classic cartoons from our childhood. 

From Rudolph the Red-Nosed Reindeer to Santa Claus Is Comin' to Town, these are the Christmas origin stories that are totally timeless.

This stop-motion animated film is based on the Christmas song of the same name. It revolves around an orphan named Aaron who meets the three Wise Men on their way to Bethlehem. The 30-minute short was created in 1968 and is a total Christmas classic.

Discover how Santa Claus came to be in this old-school cartoon. Kris Kringle was raised by elves and has a pure spirit, so he wants to deliver toys to the nearby city Sombertown. However, it's run by the evil Burgermeister Meisterburger, who banned all toys. Christmas traditions like stockings, Santa coming down the chimney, and Mrs. Claus are all evident in this classic film. 

Frosty the Snowman

December 7 — 5:15 p.m.
December 20 — 4:45 p.m.
December 21 — 11:55 a.m.

Frosty is a snowman who comes to life thanks to a magic hat, but unfortunately, his time is temporary. The kids laugh and play with the magical being and are heartbroken when he melts in the sun. However, he reassures them that he'll be back next winter. 

Rudolph the Red-Nosed Reindeer

December 6 — 7:30 p.m.
December 7 — 5:45 p.m.

Another Christmas origin story, Rudolph the Red-Nosed Reindeer is all about Santa's leading reindeer. Because he looked different, though, Rudolph didn't have the easiest time learning the ropes of the North Pole. He embarks on an adventure with another misfit, Hermie the dentist elf, to discover who they really are. 

The Nightmare Before Christmas

December 20 — 2 p.m.

The dark and twisty Christmas movie is appropriate for a multitude of holidays. Tim Burton created a universe where all of the holidays have their own worlds that don't intermingle, until Jack Skellington discovers Christmas Town and wants to take over for Santa Claus. 

The Muppet Christmas Carol

December 2 — 6:30 a.m.

Charles Dickens' classic story is brought to life by the Muppet puppets. Kermit the Frog, who is normally portrayed as cheery and kind, plays the grouchy Scrooge. 

Race for Your Life, Charlie Brown 

December 17 — 6 a.m.

Unfortunately, the Christmas Peanuts classic Merry Christmas Charlie Brown isn't airing this season, but another Peanuts movie is. In this tale, the kids go to summer camp and battle against bullies in a river-rafting competition.  

And here's the complete list of all the Christmas content coming to Freeform's annual 25 Days of Christmas. 

There are plenty of opportunities to catch the various Home Alone movies and Dr. Seuss's How the Grinch Stole Christmas, with Jim Carrey. There are also plenty of other ways to watch more holiday films on all of the streaming services, from Netflix to Disney+ to Hulu.
