- Several branches of Eastern Christianity that use the Julian calendar also celebrate on December 25 according to that calendar, which is now January 7 on the Gregorian calendar. Armenian Churches observed the nativity on January 6 even before the Gregorian calendar originated. Most Armenian Christians use the Gregorian calendar, still celebrating Christmas Day on January 6. Some Armenian churches use the Julian calendar, thus celebrating Christmas Day on January 19 on the Gregorian calendar, with January 18 being Christmas Eve.
