not celebrate Epiphany or Pentecost as seasons; for this Church, expressions such as "Fifth Sunday after Epiphany" indicate the passing of time, rather than a liturgical season. It instead uses the term "Ordinary Time". In the Catholic Church, "Christmas Time runs from First Vespers (Evening Prayer I) of the Nativity of the Lord up to and including the Sunday after Epiphany or after 6 January"; and "Ordinary Time begins on the Monday which follows the Sunday occurring after 6 January". Before the 1969 revision of its liturgy, the Sundays following the Octave of Epiphany or, when this was abolished, following the Feast of the Baptism of the Lord, which was instituted to take the place of the Octave Day of Epiphany were named as the "Second (etc., up to Sixth) Sunday after Epiphany", as the at least 24 Sundays following Pentecost Sunday and Trinity Sunday were known as the "Second (etc.) Sunday after Pentecost". (If a year had more than 24 Sundays after Pentecost, up to four unused post-Epiphany Sundays were inserted between the 23rd and the 24th Sunday after Pentecost.) The Encyclopedia of Catholic Devotions and Practices, which has received the imprimatur of John Michael D'Arcy, with reference to Epiphanytide, thus states that "The Epiphany season extends from January 6 to Septuagesima Sunday, and has from one to six Sundays, according to the date of Easter. White is the color for the octave; green is the liturgical color for the season."

For Western Christians, the feast primarily commemorates the coming of the Magi, with only a minor reference to the baptism of Jesus and the miracle at the Wedding at Cana. Eastern churches celebrate the Baptism of Christ in the Jordan. In both traditions, the essence of the feast is the same: the manifestation of Christ to the world (whether as an infant or in the Jordan), and the Mystery of the Incarnation. The miracle at the Wedding at Cana is also celebrated during Epiphany as a first manifestation of Christ's public life. Western churches Even before 354, the Western Church had separated the celebration of the Nativity of Christ as the feast of Christmas and set its date as December 25; it reserved January 6 as a commemoration of the
