<p>I sent my app in via common app at night on January 1, but when I log in on Harvard to check my application status, they say that they got it on January 2. Does this matter? Should I call in or something so they know that the app was NOT late?</p>
<p>I'm not entirely sure on this, but I think that Harvard will still be able to see when you submitted your application. If you look on your common app page, it tells you when you submitted your form and when the college downloaded it. So I'm assuming that in your case, it was downloaded to their server when they opened up their office again in the morning, but they can still see that it was submitted the night before.</p>
