Christmas is an annual holiday that celebrates the birth of Jesus. It refers to both the day commemorating the birth; and also the Christmastide season which that day inaugurates; concluding with the Feast of the Epiphany. The date of the celebration is traditional; and is not considered to be Jesus's actual date of birth. Christmas festivities often combine the observation of the Nativity with various cultural customs; many of which have been influenced by earlier winter festivals. "Do You Hear What I Hear?" is a Christmas song written in October 1962 with lyrics by Noel Regney and music by Gloria Shayne Baker. The pair was married at the time, and wrote it as a plea for peace during the Cuban Missile Crisis. It has sold tens of millions of copies and has been covered by hundreds of different artists.Christmas is an annual holiday that celebrates the birth of Jesus.
