On Sept 21, an editorial in the NY Sun assures letter writer 8-year old Virginia O'Hanlon that there is a Santa Claus.

"Yes, Virginia, there is a Santa Claus" is a line from an editorial by Francis Pharcellus Church called "Is There a Santa Claus?" which appeared in The Sun on September 21, 1897, and became one of the most famous editorials ever published. Written in response to a letter by eight-year-old Virginia O'Hanlon asking whether Santa Claus was real, the editorial was initially published anonymously, and Church's authorship was not disclosed until his 1906 death. The Sun gradually accepted its popularity and republished it during the Christmas season every year from 1924 to 1950, when the paper ceased publication.

"Is There a Santa Claus?" is commonly reprinted during the Christmas and holiday season, and has been cited as the most reprinted newspaper editorial in the English language. It has been translated into around 20 languages, and adapted as a film, television presentations, a musical, and a cantata.
