A Christmas carol is a traditional song associated with the holiday season. It often celebrates the spirit of Christmas and the values of peace, goodwill, and generosity. Many carols have a religious or spiritual message, but they can also be purely secular in nature. In the past, caroling was a way for people to spread joy and cheer to their neighbors by singing Christmas songs together. Today, Christmas carols are still popular, especially during the holiday season, and can be heard in churches, shopping malls, and homes around the world.
