One of those is the pop group TV special - the holiday period wouldn't be the same if our favourite bands didn't get their friends round for crackers and collaborations once a year.
After quizzing them on all things X Factor last month, Digital Spy and other journalists asked the boys about their seasonal special, hopes for the year ahead, and the perfect housewarming gift for a member of One Direction.
How has Christmas changed for you over the last few crazy years?
Aston Merrygold: "It's more appreciated now than any previous time I think... We're always busy and working, so it's nice to chill out and all be there with the family. We're all old enough to have a drink!"
Do you get asked to get all the big presents?
Marvin Humes: "We're grateful that we can look after our families all year round - especially our brothers who get our cast-off clothes - not hand-me-downs you've worn for five years - these are brand-new clothes. Every three months I do a clearout. It's embarrassing how much clothes we get given, and what we don't wear we give to family or charity. My little brother gets the most from me throughout the year, so when Christmas comes I don't get him anything!"
How are you going to spend your first Christmas as a married man?
Marvin: "Just like any Christmas that we spend together. For us it's just great that we get to spend that time together. We're both so busy throughout the year - especially the last three months Rochelle was in America shooting a TV show, so we've not had a lot of time together. Now we're looking forward to Christmas. It makes you appreciate the time you spend together when you're apart so much. No phones are ringing, no emails are going off - you can just really relax."
Have there been any quirks you've discovered since you've been living together?
Marvin: "We've been apart for most of it! It's kind of weird, when you've been apart for so long, and you come back together it's fresh and great. If we could have our own way we'd be together all of the time, but because of our jobs we can't. But we make it work."
How did the programme come about?
JB Gill: "It was our idea. We always wanted to do a Christmas party for our fans as well as family. We approached Sky and the production company with the idea and said this year is the year to do it. We've had a lot of requests from fans to push this idea forward.
"We decided to take a couple of months out, plan it properly, make sure that we could get everything that we wanted in place for the show - when it comes to collaborations, staging, even down to the way the lights are set.
"We've got teepees where the fans stayed overnight. We snuck around and left presents outside of their teepees, so that when they woke up it was like Christmas! JLS sent us presents! We wanted it to be a really exciting Christmas extravaganza for our fans, friends and family - the three Fs!"
As the first British boyband to do a 3D concert film, what advice are you giving the One Direction boys?
Oritsé Williams: "I think all they've got to do is be themselves. Forget that the cameras are there - just be themselves, do what they do, have fun, enjoy it. And make sure they give their fans the biggest entertainment that they've come here to see.
"With those kinds of things you can't focus too much on the cameras, or it takes over you, and you start being something that you're not. And then people are like, 'Oh, I didn't know he was like that'. But you're not really like that! Just be themselves."
Do you often chat to them?
Marvin: "Yeah, if we're not playing golf together or going to nights out, when we get the chance to - it's usually on BBM. I speak to Niall a lot. He's always messaging me about bits and pieces."
He bought your house recently - did you get him a moving in present?
Marvin: "Yeah, I did. His moving in present was a cushion of... himself! We've got the same management company, I went into our management company a couple of months ago and they've got One Direction cushions, but individual faces. So I got him a Niall face and left it as a moving in present."
What's the best Christmas present you remember from when you were little?
Oritsé: "Definitely my Ghostbusters action figures."
Aston: "I had this really, really crap bike. This bike was rubbish, man. There was a three-year period where everyone gets a new bike - that changeover from primary school to secondary school and everyone started to get a new bike. I had this crap bike for time, man... then this bike came out , and I was like, 'Wow'. Bear in mind I was three foot tall, and this bike was huge!"
JB: "You have to grow into the bike... why do mums always buy things you have to grow into?!"
What are you hoping for in 2013?
Aston: "Just to maintain the success. It's been five, six years now, and we're riding the wave, which is still high. It's just mad to think that we're doing another arena tour. We're lucky enough that people want to come see us on stage, still like our music and still love us, which is amazing."
Will there be another album?
Aston: "Yeah, definitely. We start writing in the New Year."
Aston: "Nope, we're on holiday for about three weeks over Christmas, just to chill out and relax and then it's straight back into the writing."
What kind of sound are you going for?
Aston: "Again, nothing far from this one. It's the stuff we enjoy, people are enjoying it, and we feel more than comfortable in this realm."
Have you got any New Year's Resolutions?
Aston: "I never, ever keep 'em."
JB: "When you have children, never buy them stuff that you have to grow into. Get them something for now so they can wear it properly!"
