Not to be rude, but there's bigger problems here than what strict is reporting.

• If you're going to use the CGI module, you might as well take advantage of the header() function, rather than manually printing it.
• Your logic to get a string with today's date could easily be done if you'd use the POSIX module.

  my $today_str = POSIX::strftime( "%m/%d/%Y", localtime );

• It's a little tough to deduce what you're doing in the while loop where you process the data file. Give a little though to what you're trying to accomplish there, or at least how you name your variables.
• The two screens of print statements at the end are atrocious. It doesn't scale well, and it's a complete waste of space. At a minimum, use a loop to iterate over the people you're printing information on. for best results, make basic use of a templating system, like Template Toolkit (my fav), or HTML::Template (also popular.)

Hope you can take something useful away from that.
