There is yet another of the series' endemic date and schedule contradictions here. The anti-Dementor lesson that Harry is leaving when he runs into McGonagall on her way to return his Firebolt to him is said to be his fifth – he has been unable to produce more than a faint mist in the four lessons since the first successful one; and the first lesson was in the first week of classes, "soon after the New Year". As these lessons are supposed to be every week, by that count, it can be no later than early February. However, it is only two days after the events of this chapter, as we will see, that they have the match with Ravenclaw. Less than a week later, Harry and Ron visit Hagrid and find that they are only a day away from the hearing at the Committee for the Disposal of Dangerous Creatures, which is April 20th. By that count, Scabbers should have vanished about 12 April 12, and Harry should have had about 12 lessons rather than 4; with perhaps three of them interrupted by Professor Lupin's "illness", there should still have been at least nine anti-Dementor lessons. While it's certainly true that as a teacher, Lupin will have had other things to deal with and would likely not have been able to fit twelve lessons in, still we are left with the impression that these lessons are meant to be every week, rather than every three weeks. In this case, the schedule confusion does cause a small problem in the story, as, if we miss the date of the visit with Hagrid in the following chapter, the compression at this point leads us to believe that the end-of-term exams are happening in about March.
