What's the difference between Christmas and X-mas? Or is there none? Answered

It shortens the word so it is easier to write out millions of times on your christmas cards. Also it is a slang word that has been put into popular use. I'd agree on bartboys explanation. There is no difference in meaning between the two words, Xmas is just shorter than Christmas.

Okay.

The greek letter that looks much like an X is called a Chi, and is pronounced with much throat. There is no letter P in the greek alphabet. There is a letter that looks similar to a P but is pronounced like an R.

X-mas is just a way of avoiding the Religious meaning of the word by shortening "Christ", and is therefore used much in commercial sales and whatnot.

Christmas is the proper term, it is an abbreviation of christ's mass, were X-mas is a slang word.

actualy in one culture x stands for Christ so it is Christmas

X is Greek for Christ,so instead of saying Christmas you can say X-mas and that means the same thing a as Christmas.

X is very similar to a specific greek letter. It's pronounced very similar to "Christ", so people put Xmas because it should be pronounced the same, but can be written shorter.

FACEPALM

X-mas and christmas mean the same thing but x-mas is what the government came up with so that christians didnt use the word "christ"

Xmas in the Catholic Religion is a disrespectful word for when Jesus Christ was born. That's why there have been many fights over the word Christmas and Xmas.

In addition to Bartboy's suggestion (a popular choice), another  popular explanation is that it's short for "Christ" via the greek...
X (chi) is the first letter in the Greek for Jesus.

I'd post the whole name in Greek but can't figure out how to get the letters to display.

 X-mas is simply an abbreviation for Christmas.  

No difference, X-mas is just shorter.
I think it probably has to do with the whole idea that Christ was put on a cross,
and "X" is a cross.
