Sims age question

Thanks, that answers the variable starting age. Is there a way to figure out how many days have passed since created? Previously I would have taken the days of life stage minus the days remaining but since the days of life stage is variable I'm not seeing a way to figure this out. I don't even think there is a tool that can look at the data of my sims since google search isn't turning up any relevant results when I attempt to search. After your post I had the idea to check to see if MCCC could show any age data. I discovered it shows X/96 for each of them. As an experiment I created a new family and what I discovered is that upon creation the variable days of life stage is determined by starting each sim at a random number of days into the 96 days. Unless there is some sort of data I can view that indicates what number of days they started with I can't think of a way to determine the number of days that has passed since creation.
