when was the term xmas invented

The term "Xmas" is a shortened version of "Christmas" that has been in use since the 16th century. It was popularized by the English clergyman and writer Charles Wycliffe, who used the term in his writings to refer to Christmas. Over time, it became a commonly used abbreviation for "Christmas" and is still used today. However, some people feel that the use of "Xmas" is disrespectful to the religious origins of the holiday and prefer to use the full word instead.
