ARMENIAN CHRISTMAS
Why Armenians Celebrate Christmas on January 6th?
Armenian Christmas," as it is popularly called, is a culmination of celebrations of events related to Christ’s Incarnation. Theophany or Epiphany (or Astvadz-a-haytnootyoon in Armenian) means “revelation of God,” which is the central theme of the Christmas Season in the Armenian Church. During the “Armenian Christmas” season, the major events that are celebrated are the Nativity of Christ in Bethlehem and His Baptism in the River Jordan. The day of this major feast in the Armenian Church is January 6th. A ceremony called “Blessing of Water” is conducted in the Armenian Church to commemorate Christ’s Baptism. It is frequently asked as to why Armenians do not celebrate Christmas on December 25th with the rest of the world. Obviously, the exact date of Christ’s birth has not been historically established—it is neither recorded in the Gospels. However, historically, all Christian churches celebrated Christ’s birth on january 6th until the fourth century. According to Roman Catholic sources, the date was changed from January 6th to December 25th in order to override a pagan feast dedicated to the birth of the Sun which was celebrated on December 25th. At the time Christians used to continue their observance of these pagan festivities. In order to undermine and subdue this pagan practice, the church hierarchy designated December 25th as the official date of Christmas and January 6th as the feast of Epiphany. However, Armenia was not effected by this change for the simple fact that there were no such pagan practices in Armenia, on that date, and the fact that the Armenian Church was not a satellite of the Roman Church. Thus, remaining faithful to the traditions of their forefathers, Armenians have continued to celebrate Christmas on January 6th until today. In the Holy Land: January 18thIn the Holy Land, the Orthodox churches use the old calendar (which has a difference of twelve days) to determine the date of the religious feasts. Accordingly, the Armenians celebrate Christmas on January 18th and the Greek Orthodox celebrate on January 6th. On the day before Armenian Christmas, January 17th, the Armenian Patriarch together with the clergy and the faithful, travels from Jerusalem to the city of Bethlehem, to the Church of Nativity of Christ, were elaborate and colorful ceremonies take place. Outside, in the large square of the Church of Nativity, the Patriarch and his entourage are greeted by the Mayor of Bethlehem and City officials. A procession led by Armenian scouts and their band, advance the Patriarch into the Church of Nativity, while priests, seminarians and the faithful join in the sing of Armenian hymns. Afterwards, church services and ceremonies are conducted in the Cathedral of Nativity all night long and until the next day, January 18th.
I believe the full title - as per the ROCOR Liturgical Calendar - is “The Nativity According to the Flesh of our Lord, God and Saviour Jesus Christ.” Some other examples:
