I'd do that but i want to get it to like one or two days before she ages up so that i can fulfill her needs/ get her to raduate with an A etc....plus the skipping of whole days at a time would come in handy for other families. thanks though
I don't know of a way to set the clock forward... which doesn't mean there isn't one But if you just want to speed up gameplay... in the sense that the clock goes by faster per sim action... you can use Twallan's Relativity mod to do that.
I don't understand, though, why you don't just get her to an A now, and then age her with the cake... or even just age her now, and if her grade isn't high enough to pick her traits, just let the game pick, and then change em to what you want with a cheat. Yes, that's cheating, but so would skipping a day be, and the result is the same.
