Orthodox Christmas - Russia

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), commemorating the birth of Jesus Christ, is celebrated on 25 December in the Julian calendar used by the church, which falls on 7 January in the common Gregorian calendar. Christmas is considered a high holiday by the Russian Orthodox Church, one of the 12 Great Feasts, and of only 4 Feasts preceded by a period of fasting. 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 honour 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 the new year.

In Russia, the Christmas holiday became the official celebration with the baptism of Rus' ordered by Prince Vladimir in the late 10th century. However, given the early Christian community Kievan Rus', celebration may have a longer history.

During the early-mid Soviet period, religious celebrations were discouraged by the official state policy of atheism until 1936, but despite this, Christmas was marked by the Soviet regime on December 25. Christmas tree and related celebrations were gradually eradicated after the October Revolution. In 1935, in a surprising turn of state politics, many Christmas traditions were re-adopted as part of a new secular New Year celebration. These include the decoration of a tree, or "ёлка" (spruce), festive decorations and family gatherings, the visit by gift-giving "Ded Moroz" (Дед Мороз "Grandfather Frost") and his granddaughter, "Snegurochka" (Снегурочка "The Snowmaiden").
