The mistakes are covered by Writers Cannot Do Math. If someone were to, however, write a fic explaining why all of these dates were in fact correct or why everyone was mistaken In-Universe, you'd have a Fix Fic.

The Harry Potter series has major Writers Cannot Do Math issues, especially with the calendar. A particular fan fiction work repeatedly has comments along the lines of "J. K. Rowling said such and such date is on this day of the week, but in reality it's on that day", in the context of using the real day. Similar issues exist with the date of Easter, where the fan fiction author comments about Rowling having gotten it wrong.
