Corrected entry: At the end of the movie when Ferris' parents come home you see their foyer by the front door loaded with get well flowers and balloons, etc. Who accepted the deliveries if no one was home all day? Rooney wasn't around long enough to have brough ALL those flowers and gifts inside. Also, as much as he despises Ferris, I'm sure he would rather see them on the front porch to wilt. The only reason he signed for the first one was because he just happened to be standing on the front porch when the deliveryman arrived.

Correction: You can see his sister accepting the "get-well messages" (like the "nurse" singing), so we can assume that she collected the flowers as well.

Correction: And/or a neighbor/friend with a spare key, one of many people in Ferris' thrall enough to visit and see to all those packages?

Corrected entry: At the beginning of the movie, Ferris' mother is examining her sick son and says to Mr. Bueller, "He doesn't have a fever, but his hands are cold and clammy and he says he's seeing spots." At the end of the movie, when Ferris narrowly beats his parents home and they enter his bedroom, Mrs. Bueller again touches her son's forehead and says, "You're still warm." I thought he didn't have a fever.

Correction: She assumes it's from the illness running it's course through the day, She assumes that in the morning he wasn't feverish yet, then the fever came as the sickness progressed over the day, and this is the tail end as he recovers.

Corrected entry: The movie supposedly takes place in April, however based on Chicago's climate, it is quite clear that the actual filming was conducted well into the summer months based on how full and leafy all the trees are, not to mention the ivy on the outfield wall at Wrigley Field which does not become fully developed with leaves until late May at the earliest.

Correction: Do they specifically state the month in the movie? Also, this is Chicago, what with all the snow days they have any given year, it's conceivable the make-up days have pushed Graduation and things back an entire month.

Correction: Given the baseball game they went to, the movie took place on June 5.

The baseball game was obviously staged for the film.

The baseball game was definitely not staged for the film. The baseball scenes were filmed during a real Cubs game in September (when filming took place). John Hughes added footage from the earlier June game during editing to make it appear they attended the June game.

Corrected entry: At the beginning of the movie when Ed Rooney is talking to Ms. Bueller he says 'if he thinks he can just coast through this month...' then Ferris says later something about 'a couple of months until we graduate'

Correction: Some, if not most, American high schools tally student grades and absences through the month of, say, April in order to have time to calculate the information they need for graduation near the first of June. If it is near the beginning of April (they don't specifically say), Ferris can try to 'coast through this month' because he knows anything that happens in May won't count, hence 'a couple of months until we graduate' - April, May, and possibly a week or two in June.

Corrected entry: When Ferris and his friends are at the fancy restaurant where his father is eating. They notice him waiting for a cab and freak out and sneak into the cab right before Ferris' father. Why not just wait inside for a minute until he leaves?

Correction: Ferris is confident and daring to the point of absurdity. Several hours later he appears on a parade float, in the view of thousands. To him, sneaking into a cab under his father's nose is a perfectly normal thing to do.

Correction: Knowing Ferris, he may very well be skipping out on the check, and must get off the premises ASAP anyway (and can't bribe a waiter to smuggle him and company out the back). Therefore, there is danger for him either way, and this is the lesser risk.
