Midnight of the 31st or the 1st?

<p>For Columbia and other colleges do I need to submit the application before midnight of the 31st or can I still submit it on January 1st?</p>

<p>you can submit it on Jan 1st. The latest you can submit it is at 11:59 Jan 1st, but for practical reasons send it early.
I don't know if it has ever happened before, but what if commonapp crashes from the surge of applications.</p>

<p>Alright thanks because I got an email from notre Dame that said their app was due the 31st lol...</p>
