when did night before christmas come out

The book "A Visit From St. Nicholas" was first published anonymously in 1823 and is widely believed to be the inspiration for "The Night Before Christmas". However, the specific publication date of "A Visit From St. Nicholas" is not known with certainty as it was not initially published under its author's name. The author of the poem, Clement Clarke Moore, has since been widely credited as the writer of the classic Christmas story.
