Probably it will be the same as when in 1900 the date shifted from Jan 6 to Jan 7 - none. The terminology used in the news release is nothing more than the usual media shallowness and ignorance of the true issue of the calendar. We all know that the feast of our Lord's Nativity is never celebrated on any date other than Dec. 25 - its just that Dec 25th on the Julian Calendar (used for Church feasts by the majority of Orthodox Christians) does not coincide Dec 25th on the Gregorian Calendar (which is the generally accepted civil calendar). So let's try to not confuse the issue with red herrings. Fr David Moser
