The Feast of the Baptism of the Lord, or Theophany, is the feast day commemorating the baptism of Jesus in the Jordan River by John the Baptist. Originally the baptism of Christ was celebrated on Epiphany, which commemorates the coming of the Magi, the baptism of Christ, and the wedding at Cana. Over time in the West, however, the celebration of the baptism of the Lord came to be commemorated as a distinct feast from Epiphany. It is celebrated in the Catholic Church as well as the Anglican and Lutheran Churches on the first Sunday following The Epiphany of Our Lord (January 6). Some Lutheran churches celebrate it on the Sunday before Lent, or Quinquagesima. Celebration in the Eastern Christian Churches In the Eastern Orthodox and the Eastern Catholic Churches, the Baptism of the Lord is celebrated as an integral part of the celebration on January 6, the Great Feast of the Theophany. For those churches which follow the traditional Julian Calendar, January 6 falls on January 19 of the modern Gregorian Calendar (see Epiphany (holiday) and Theophany for details).

The Tridentine Calendar had no feast of the Baptism of the Lord for almost four centuries. Then the feast was instituted, under the denomination "Commemoration of the Baptism of our Lord", for celebration on 13 January as a major double, using for the Office and the Mass those previously said on the Octave of the Epiphany, which Pius XII abolished; however, if the Commemoration of the Baptism of Our Lord occurred on Sunday, the Office and Mass were to be those of the Feast of the Holy Family without any commemoration. In his revision of the calendar five years later, Pope John XXIII kept on 13 January the "Commemoration of the Baptism of our Lord Jesus Christ", with the rank of a second-class feast. A mere 14 years after the institution of the feast, Pope Paul VI set its date as the first Sunday after January 6 (as
