The Armenian Apostolic Church still uses the old Julian Calendar, Christmas is celebrated on January 6th. The Christmas holiday season starts on New Year's Eve (December 31st) and continues until the old Julian calendar's New Year's Eve on January 13th.
Up to 97% of Armenians follow Christianity, which has existed in Armenia for over 1,700 years. Armenia has its own church, the Armenian Apostolic Church, which most Armenians follow. Christianity has a strong influence in the country, but there is a small presence of other religions too.
