Do you think Christmas will still be celebrated in some form 100 years from now?

yes.

Of course. Japan should know this very well. Some traditions really continue for centuries while some are just fads and fade away. Here are just some facts about it:

Christmas has been a US federal holiday since 1870

It was Pope Julius I that decided to place Jesus' birth at Dec 25 so it would coincide with the Romans' Saturnalia festival ( a pagan festival meant to celebrate Saturn and involves Christmas-y things)

the Christmas season is celebrated in the Philippines as early as September (Trust me, I'm Filipino)

Yes. It’s the winter solstice..

I don’t think people will waste much time with the religious side of it in 100 years though.

Yes. As strangerland pointed out, the religious side of it will probably continue to slide but the solstice predates Christianity. Anyway, the nativity story is cute and some of the songs are nice.

A good old Norse booze-up will stand the test of time,

Religions and cults may come and go, but as long as there's money to be made out of Xmas, then it's here to stay.

Prediction:

In 100 years, when the remnants of humanity live in domed communities subsisting on a diet of insect paste and recycled waste liquids...

there will still be Christmas.

spinning, domed or doomed?

Will there still be humanity in 100 years' time, for that matter? Christmas has kind of trucked on for 2,000 years. Why should it suddenly disappear? In fact why ask the question?

It will be celebrated for centuries to children dream Santa Claus.

Probably. The Yuletide season and pagan celebrations going back further morphed into Xmas today. I'm sure some sort of celebration will be around.

Brexit will still be an ongoing process, though ;-)

Of course it will.....it is the best present ever to online commerce,normal commerce.....Christmas is the gift that keeps giving.

It's an interesting question. If I remember my Christmas history correctly, Christmas as we more or less know it today has only been around since the early 19th century, not the 2,000 years that many Christians and non-Christians assume it has. But to answer the question, it's quite possible it won't be. Imagine a world of facism and dictatorships where Christmas is banned. Even today, Christmas is not openly celebrated, I believe, in some countries. North Korea is one. I heard Brunei isn't Christmas-friendly either. If Islamic State had taken over Iraq and Syria, I bet they would not have allowed Christmas. Imagine a country where all public references to Christmas were banned and people could celebrate only in the privacy of their homes but even that would be under threat of death. The world can become like that, either through religious extremism or fascism. We are already seeing many democracies failing to function properly. Anything can happen. Fortunately, I won't be around in 100 years to see what the world will be like.

Yes, because the capitalists stole Christmas from the Christians, and the Christians stole it from the Pagans.

OF COURSE!

Yes, it's been celebrated for just over 2000 years.

Minus 336.

Hopefully, the commercialization will go away and it will be more about spending time with family.
