Removing dates from posts

Hi all,
I have been away from this for a while and am still a newbie.
Below is my single.php file. Can someone tell me how to comment out the calls to put dates on all of the blog posts? Do I need to edit all of the files below before it will work on the blog posts?

Thanks so much!

index.php
archive.php
category.php
single.php
page.php
