I don't know whether those sources are to be trusted. If they are, I don't know when the switch to the 'astronomically correct' periods took place...

Indeed this source doesn't appear to be reliable. They include an illustration (Très Riches Heures, 1415 ca) which clearly shows the transition from Scorpio to Sagittarius on November 14th. This is roughly consistent with You are not allowed to view links. Register or Login to view. (three centuries earlier). I doubt that in the middle ages there ever was a belief in a zodiac sign / month identity, therefore I doubt that there ever was any switch.
