How many countries celebrate Christmas?

Christmas is observed in some form or another in over 160 countries around the world. Some countries with predominantly Christian populations, such as the United States, Canada, Mexico, and many European nations, celebrate Christmas as a major religious holiday with customs such as exchanging gifts, decorating trees, and attending religious services. Other countries with smaller Christian populations, such as China and Japan, may celebrate Christmas more commercially or as a cultural event, with activities such as gift-giving, shopping, and festive decorations.
