Here's a really cool chronology chart that breaks down the time period of every Disney movie. It was done by Aish from the Disney's New Groove website - a cool website that i didn't knew and that i suggest you have a look at HERE - who gave the following explanation:
"Disney movies in order of historical setting. (Excludes most of the package films. Some films, eg The Lion King, are impossible to pin down exactly and some, like Aladdin and Treasure Planet, are anachronistic, so these are estimations. A few have been split into 2 if there is more than one time period in the movie, and sequels have been put together.)"
