Usage note

The abbreviation Xmas for Christmas dates from the mid 16th century. The X is the Greek letter chi, the initial letter in the word Χριστός ( Chrīstos ) “Christ.” In spite of a long and respectable history, today Xmas is offensive to many, perhaps because of its associations with advertising. It is not used in formal writing.
