We have already seen that we can't trust the "real" calendar to give us the days of the week when we know the date, but just for interest sake, Halloween in 1991 was on a Thursday. The Gryffindor first years had Charms that morning and learned the [Wingardium Leviosa] spell.

Death Eaters history & timelines witches and wizards Harry, Hermione, and Ron follow Quirrell after the Philosopher's StoneThey overcome the various protections, and defeat Quirrell/Voldemort's attempt to steal the Stone.
The dates of this event are contingent on the dates of exams in Harry's first year. We are given dates for exams in books two and three--the first week of June--but that doesn't seem to be a hard and fast rule. The calendar for this book gives the date as June 4, based on the exam dates in the other books, but here on the timeline we'll play it a bit safer and just go with "early June."
