Christmas in Russia (Russian: Рождество Христово Rozhdestvo Khristovo, in the Russian Orthodox Church called Е́же по пло́ти Рождество Господа Бога и Спа́са нашего Иисуса Христа) is celebrated on 7 January and marks the birthday of Jesus Christ. Christmas is mainly a religious event in Russia. On Christmas Eve (6 January), there are several long services, including the Royal Hours and Vespers combined with the Divine Liturgy. The family will then return home for the traditional Christmas Eve "Holy Supper", which consists of 12 dishes, one to honor each of the Twelve Apostles. Devout families will then return to church for the "всенощная" All Night Vigil. Then again, on Christmas Morning, for the "заутренняя" Divine Liturgy of the Nativity. Since 1992 Christmas has become a national holiday in Russia, as part of the ten-day holiday at the start of every new year.
