'Xmas' is another way saying 'Chirstmas' which is supposed to be more secular than the latter. However, the 'X' part of 'xmas' was used by early Chirstians to identify themselves as a follower of Christ. By marking an 'X', they signified either a safe house, gathering place, or the like. X is the character for the Greek letter "Chi" which was the first letter of Jesus' name in Greek.

To say that xmas may have no religious value today is perhaps true, but ironic becasue xmas and Chirstmas are literally one in the same.

The multi-religious or non religious version of Christmas. X being the variable 'holiday of choice', or even lack there of. This holiday is celebrated similarly to Christmas, but without the christian beliefs. It is a time of gift giving and spending time with family.

The x comes from the Greek word xioto meaning Christ it is not meant to take Christ out of the word Christmas just a shorter way of saying it

christmas(supposedly used to be secular)

A cool and short way to say Christmas without any reference to the "Christ" religious part. Good term to forget any deep meaning of Christmas and enjoy the presents.
