Orthodox Christians follow the Julian calendar which places the day on January 7. The majority of Christians follow the modern day Gregorian Calendar which places Christmas on December 25. In the Orthodox tradition, a 40-day fast occurs before the Nativity of Our Lord. The faithful abstain from foods derived from animals on Wednesdays and Fridays. Sundays beforehand honor the old covenant between God and Abraham and the new covenant between God and those who believe in Christ.
