It depends on when the school year started really. In my experience, the school year normally starts sometime in September (depending on your location, it could be the start or middle). Assuming that RWBY has a similar calender just for convenience, it would make more sense that they use 4 semesters. If each semester was 6 months, it would already be past new years by now and the festival would have been over. If a semester is 3 months, it would fit better as the festal is almost here and the second term has just started, so we would be within the first month of the second term (late November or early December).
