The Armenian Apostolic Church celebrates Christmas on January 6th. On this day it also celebrates the Baptism of Jesus and the Epiphany which means The Revelation of The Son of God (Asdvadz-a-Haydnoutioun).
Epiphany is now mainly the time Churches remember the Visit of the of Wise Men to Jesus.
The Christmas Eve meal is called (Khetum) made of Armenian traditional food and desserts.
Until the 4th Century, the Catholic Church celebrated also Christmas on the 6th of January but as Christianity spread in Europe, the day was merged with a Roman Pagan holiday, dedicated to the birth of The Sun, on December 25, in order to override it. However, the Armenians decided to stick with the traditional and correct day for Christmas.
