[BY DESIGN] [DU] [S] Sims have to go to class on holidays

Yes, it's true you have to go to class on holidays for university. It makes sense, for the Sims, that you cannot have these days off. In real life, you only get a few holidays per term and it doesn't affect your class time. In the sims, a term is only a week. If you have a holiday on a particular day, Wednesday, and your term runs Tuesday to Monday, then the term cannot be extended one day to make up the class. The missed class is on Wednesday (M-W-F classes), but the added day would a Tuesday (T-R class). This means you would be missing a whole day of progress for the holiday and possibly even exams if the holiday was on last day of the term. Even if terms were adjusted to start on a day that wouldn't cause an issue, then you get extra holiday time to study. It would also make you waste time on progress for your degree if they pushed back your start of term to adjust for holidays. Going to a career, school or high school doesn't have this issue because you don't have different classes on different days. Missing a day in university makes it super complicated. The devs have chosen to not allow skipping days for holidays.
