Christmas is the Christian festival celebrating the birth of Jesus.

The English term Christmas (“mass on Christ’s day”) is of fairly recent origin. The earlier term Yule may have derived from the Germanic jōl or the Anglo-Saxon geōl, which referred to the feast of the winter solstice. The corresponding terms in other languages—Navidad in Spanish, Natale in Italian, Noël in French—all probably denote nativity. The German word Weihnachten denotes “hallowed night.” Since the early 20th century, Christmas has also been a secular family holiday, observed by Christians and non-Christians alike, and marked by an increasingly elaborate exchange of gifts. In this secular Christmas celebration, a mythical figure named Santa Claus plays a pivotal role. Christmas is celebrated on December 25.
