Disney has no set date for removing Christmas decorations, as they tend to keep the decorations up for as long as they can. However, the official end of the holiday season is typically January 6th, also known as the Feast of the Epiphany or Three Kings Day. After this date, you may begin to see some decorations come down. It's worth noting that the decision to remove the decorations is ultimately up to the individual park and may vary based on the popularity of the decorations and how much foot traffic the park sees.
