Your guide to festive, post-present TV

You can count on chestnuts of a different kind today if you’re going to hunker down and watch some TV.

With Christmas Day in full swing, here are some of our choices —both holiday-themed and fun — that will help keep you in a festive holiday mood.

If you want to start your celebration early, FX will air the movies “Marmaduke,” “Madagascar 2: Escape 2 Africa” and “Monsters vs. Aliens” back-to-back beginning 8 a.m.

The holiday fun kicks into high gear tonight, with the big-screen animated movie, “Horton Hears a Who!” starring the voices of Jim Carrey and Steve Carell (8 p.m. on Ch. 4).

Carrey returns, in live-action form, in “Dr. Seuss’ How the Grinch Stole Christmas,” the 2000 big-screen movie based on the classic cartoon about the Grinch trying to rob a small town of its holiday cheer. Look for a future “Gossip Girl” star Taylor Momsen in the cast.

There’s also “National Lampoon’s Christmas Vacation” (9 p.m. on ABC Family), which has become a holiday staple with stars Chevy Chase and Beverly D’Angelo (who recently reunited for several Old Navy commercials based on this movie).

ABC Family’s sister network, Disney Channel, offers up “Good Luck Charlie, It’s Christmas!” a special episode of “Good Luck Charlie” with series stars Bridgit Mendler and Jason Dolley, while sci-fi fans can revel in a Christmas special of “Dr. Who” called “The Snowmen” on BBC America (9 p.m.) and a marathon of the “Dr. Who” spinoff, “K-9” airing on Syfy (starting at 8 p.m.)

And, for those who want to cap off their holiday with some exciting NBA action, there are several options, including the Nets-Celtics game on ESPN at noon and the Knicks-Lakers on ABC at 3 p.m.
