Ethiopians believe that Jesus Christ, the spiritual leader of Christians, was born on January 7.
This is because the ‘Coptic Christians’ (a term used to refer to the indigenous Christian population in Egypt and the Middle East) use the Julian calendar of the Coptic Orthodox Church against the Gregorian calendar.
According to the Julian calendar Christians in Ethiopia follow, the Christmas Day celebration is on January 7, every year, as against the largely celebrated December 25, by most people worldwide.
