It's estimated that approximately 90% of Americans celebrate Christmas, making it one of the most widely observed holidays in the country. However, the exact percentage can vary depending on how you define "celebration." For example, some people may simply acknowledge the day by exchanging gifts or having a family gathering, while others may fully immerse themselves in the holiday spirit with decorations, meals, and other traditions. Regardless, Christmas is undoubtedly an important part of American culture and a significant event for many people.
