Copy a file from one dir to another by date

Hello, I only have basic knowledge of writing batch files and I have searched for what I am trying to do but I can't figure it out. Basically I have an RSS feed that I want to automatically update daily. I need the batch file to get today's date, scan the source folder to find the file with today's date, copy it to the RSS folder, and then rename it to the name of the feed.

Thank you.
