Factual error: When Joey is talking to the Professor, he mentions that her Birthday is the next day. Dawson also helps Joey celebrate her Birthday early at Midnight that night. Clearly this is some time in early Fall, when the Semester first starts at Worthington; probably August or September. But during the Season 5 Finale, Bessie hands Joey her Passport which has Joey's Birthday listed as May 13, 1983. Also, in previous years of the show, Joey's Birthday was never shown to be in the Fall. She didn't even start learning to drive until later in Season 3.
