Stupid Little Question on Common App

<p>This isn't very important. In the Family section of the Common App, you can list siblings in college. They ask for dates of attendance, with a start and end date. The trouble is, my brother is currently in college. For the end date, should I put the current date, or his projected graduation date? And yes, I know adcoms aren't going to make a fuss over it – they'll probably know what I was thinking whichever way I do it, but if there's a right way I'd like to know. Thanks.</p>
