Traditionally, Armenians fast during the week leading up to Christmas avoiding all meat, eggs, and dairy products. Devout Armenians may even refrain from food for the three days leading up to Christmas Eve, in order to receive the Eucharist on a "pure" stomach. Christmas Eve is particularly rich in traditions. Families gather for the Christmas Eve dinner ("khetum", Խթում), which generally consists of rice, fish, "nevik" (նուիկ, a vegetable dish of green chard and chick peas), and yogurt/wheat soup ("tanabur", թանապուր). Dessert includes dried fruits and nuts, including "rojik", which consists of whole shelled walnuts threaded on a string and encased in grape jelly, "bastukh" (a paper-like confection of grape jelly, cornstarch, and flour), etc. This lighter menu is designed to ease the stomach off the week-long fast and prepare it for the rather more substantial Christmas Day dinner. Children take presents of fruits, nuts, and other candies to older relatives. "On the eve of the Feast of the Nativity and Theophany of The Lord Jesus Christ, the Jrakalouyts Divine Liturgy (the lighting of the lamps service) is celebrated in honor of the manifestation of Jesus as the Son of God (theophany)" In addition to the Christmas tree ("tonatsar", Տօնածառ), Armenians (particularly in the Middle East) also erect the Nativity scene. Christmas in the Armenian tradition is a purely religious affair. Santa Claus does not visit the nice Armenian children on Christmas, but rather on New Year's Eve. The idea of Santa Claus existed before the Soviet Union and he was named " kaghand papik" (Կաղանդ Պապիկ), but the Soviet Union had a great impact even on Santa Claus. Now he goes by the more secular name of Grandfather Winter ("dzmerr papik", Ձմեռ Պապիկ).
