Sequel?

The movie opens up after the first one ends and Mrs.Potts begins telling a story of what happened back when they were still under the spell. She begins the story by telling how the Beast saved Belle from a pack of wolves, and that's when the flashback for the story begins. So The Enchanted Christmas takes place after Belle is saved by the wolves in the first one but before Belle and Beast dance to "Tale As Old As Time". Presumably, it happened during the timeframe of the song "Something There" since that song is a montage covering Belle's time in the castle.
