What day does classes start at uni? *SOLVED*

Huh. I always thought the first day of term was the first week day after you enrolled, which is why I always enroll on a Tuesday/Wednesday so that I've got a full weekend as part of the term. Maybe it depends on what time of day you enroll, too. That is, the game may give you 24 hours to settle in, and then the next 8am on a weekday is the start of term.

Might bear some experimenting to see the exact parameters.

Yeah, silly me. The term all depends on what day you enroll your sims. So since I start each family rotation on Sundays, that's when I enroll my sims. Which means, they start class on Tuesday even if they have a class scheduled for Monday. So now I'm thinking of adjusting my rotation to possibly Fridays. Or just stick with what I have now. We shall see. Thanks guys!

You are right @DaWaterRat. If you enroll on a Tuesday it will start on a Wednesday; if you enrolled on Friday or Saturday it will start on a Monday.
