I’d imagine a ton of Christians in the West and non-Christians are absolutely oblivious to the fact that ‘Christmas’ is not only celebrated on 25th December but ALSO on January 7th.
The Orthodox Church use the Julian calendar where there is a difference of 13 days when compared to the Gregorian calendar which the West uses. This winds up leaving the Orthodox Church celebrating Christmas on January 7th.
The Eastern Christians observe Christmas in a different manner to the West. There's more emphasis on religious traditions and practices such as fasting and praying 40 days before Christmas.
Jesus taught people to do the Will of God (according to Mark 3:35) in order to become his brothers, mothers or sisters. A Muslim means one who submits to the Will of God. Do you want to become a brother of Jesus? If yes, become a Muslim.
