Disneyland typically celebrates Christmas starting in mid-November. During this time, the park is decorated with festive lights, garlands, and other decorations to create a magical atmosphere. Some popular attractions and shows are also given a Christmas theme, such as the "World of Color" show, which features a holiday-themed soundtrack and visuals. Additionally, many shops and restaurants offer holiday-themed merchandise and meals to celebrate the season. Keep in mind, however, that some of these events may not be available due to COVID-19 restrictions.
