The original date of the celebration in Eastern Christianity was January 6, in connection with Epiphany, and that is still the date of the celebration for the Armenian Apostolic Church and in Armenia, where it is a public holiday. As of 2013, there is a difference of 13 days between the modern Gregorian calendar and the older Julian calendar. Those who continue to use the Julian calendar or its equivalents thus celebrate December 25 and January 6, which on the Gregorian calendar translate as January 7 and January 19. For this reason, Egypt, Ethiopia, Eriteria, Russia, Georgia, Ukraine, Serbia, the Republic of Macedonia, and the Republic of Moldova celebrate Christmas on what in the Gregorian calendar is January 7. Eastern Orthodox Churches in Bulgaria, Greece, Romania, Antioch, Alexandria, Albania, Finland, and the Orthodox Church in America celebrate Christmas on December 25 in the revised Julian calendar, corresponding to December 25 also in the Gregorian calendar.
