Removing Drafts By Date

Hello,

I just recently installed an RSS aggregator to my site, to help me import posts that are being syndicated by other sites. The issue I have encountered is that I am not interested in any new post that was made before 1-1-16. Is there any plugin that will allow me to bulk delete all of the drafts before this date? Or will I have to do this via PHPMYADMIN?

Thanks in advance for any information that is sent along.
