Quick sort of question. Holidays and University.

I plan university terms so that they don't overlap major holidays such as Winterfest. Sometimes though, I just let sims power through the holiday. If they have time to celebrate then great but if not, I don't get too worked up. I figure that the holidays are there to be celebrated if I want and if the sims being played have time. I look at the holiday schedule before starting a term. I tend to rotate around during the short break in terms so that's when I consider if I want to be playing a uni student for a holiday or if I want to go play some other household for it.
