It happens rather soon after the 1st, I would say around the 4th and the 5th. I believe it's staggered and "magically" happens overnight. I know for a fact that the Epcot Christmas tree was still up on 1/7, when we ran around it finishing the 1/2 marathon. It was gone by Monday, the 9th. Also, the Osborne lights lasted until the 6th or 7th. Bottom line, you'll see some but not all!
