The majority of countries around the world do celebrate Christmas in some form or another, but the exact traditions and customs can vary greatly. For example, in some countries, such as Russia and Poland, Christmas is celebrated on January 7th instead of December 25th. In addition, some countries, such as Japan and China, do not celebrate Christmas at all. However, many countries around the world have adapted their own unique traditions and customs to celebrate the holiday, making it a truly global celebration.
