The Feast of the Epiphany ( Twelfth Night )

On January 6 the Church of the East, along with most other Christian churches, celebrates the Feast of the Epiphany. The Epiphany (Beth Denkha) is an ancient festival observance of the Church. It has been celebrated at least from the 3rd century of the Christian era. The word Epiphany is of Greek origin, and it means "manifestation", and the Greek title of the feast has usually carried over into other languages, though it has been translated among the Syriac-speaking churches ("Denkha" carries the same meaning). The feast was from the beginning a celebration of the Baptism of Christ, and was one of the three principle feasts of the early Church: Epiphany, Easter, and Pentecost. From the 5th century the Western churches began to transform the feast-day into a celebration of Christ's manifestation to the Gentiles, and the three "Kings" (Magi) became the central figures (apart from our Lord) in the day's festivities. However, in the Eastern churches the commemoration of the Baptism is still the central feature.

In western Christian tradition, January 6 is celebrated as Epiphany. It goes by other names in various church traditions.  In Hispanic and Latin culture, as well as some places in Europe, it is known as Three Kings’ Day (Span: el Dia de los Tres Reyes, la Fiesta de Reyes, or el Dia de los Reyes Magos; Dutch: Driekoningendag). Because of differences in church calendars, mainly between the Eastern Orthodox and the western Catholic and Protestant traditions, both Christmas and Epiphany have been observed at different times in the past.  Today, most of the Eastern Orthodox traditions follow the western church calendar. The exceptions are some Greek Orthodox Churches and related traditions (e.g., Russian and Serbian Orthodox) that still follow the older calendar and celebrate Epiphany as the Theophany on January 19th.

Epiphany is the climax of the Christmas Season and the Twelve Days of Christmas, which are counted from December 25th until January 5th.  The day before Epiphany is the twelfth day of Christmas, and is sometimes called Twelfth Night, an occasion for feasting in some cultures. In some cultures, the baking of a special King's Cake is part of the festivities of Epiphany (a King's Cake is part of the observance of Mardi Gras in French Catholic culture of the Southern USA).
