Christmas trees are usually put up between late November and mid-December, depending on the family's traditions and preferences. The tree is often decorated with lights, ornaments, and other festive decorations to create a cheerful and festive atmosphere. Some families also add extra decorations, such as tinsel, garlands, and wreaths, to further enhance the holiday spirit. The Christmas tree is typically left up until after the holiday season has passed, usually around New Year's Day or shortly thereafter.
