QandA: Why is Christmas celebrated January 7th?Date posted: December 10, 2015
January 7th is considered “Orthodox Christmas” and is celebrated around the world in strong orthodox settings (ie. Russian, Ukrainian, and Serbian orthodox churches). Egypt has a strong orthodox church, too, known as the Coptic Church. The Coptic Church is the largest percentage of Christians in Egypt, so all Egyptian Christians follow the holidays according to the Coptic Church’s calendar.
The reason they celebrate Christmas on January 7th is that they follow the Gregorian calendar, rather than the Julian one. December 25th in the Gregorian calendar is the same as January 7th in the Julian Calendar. The Julian calendar pre-dates the Gregorian calendar, which is why the majority of the world celebrates on December 25th, rather than January 7th.
