Welcome to our Forum, WolfGoddess. I've removed your poll because it wasn't the proper use of polls here and it wouldn't help you get an answer at all.
As for your specific question, in the PC version of the game, I've had this happen more than once. Sometimes they age up around 8:00 p.m. like regular Sims do, but sometimes they miss it by a day or so. I've always just waited it out. I'm sorry I can't give you any more information.
