"The Twelfth of Never" is a popular song written in 1956 and first recorded by Johnny Mathis the following year. The title is a popular expression, which is used as the date of a future occurrence that will never come to pass. In the case of the song, "the 12th of Never" is given as the date on which the singer will stop loving his beloved, thus indicating that he will always love her. Mathis initially disliked the song, which was released as the flip side to his number 1 hit single "Chances Are".
