does the whole world celebrate christmas

The whole world does not celebrate Christmas, but many countries around the world have adopted it as a holiday and have their own unique traditions and customs. For example, in Japan, Christmas is not a public holiday but is still celebrated by many families with special meals and gifts. In China, Christmas is a secular holiday and is often celebrated as a romantic holiday by couples. In Australia, Christmas is celebrated in the middle of summer, so the traditions and customs are different from those in the northern hemisphere.
