what does xmas stand for

The abbreviation "Xmas" stands for Christmas, and is a shortened version of the word. It's derived from the Greek letter "Chi," which is the first letter of "Christ" in Greek. Using "Xmas" instead of "Christmas" has become a common shorthand for the holiday, although some people feel that it takes away from the religious significance of the name. However, both terms are still widely used and understood by most people.
