giulienk and giant are correct - use a CPAN module for this. But, i am sure that you are still itching to get this code work - the first glarring error i see (besides no strict!!) is this:

@thismonth = qw( $jandays $febdays $mardays $aprdays ...

# you obviously meant:
@thismonth = ($jandays,$febdays,$mardays,$aprdays, ...

But even with that fix, you will still get erroneous results. My advice? Start over, use strict, use the HTML methods from CGI - at least use CGI.pm's header(). Learn a templating module such as Template-Toolkit or (my favorite) HTML::Template. That or use one of the aforementioned CPAN modules that generats calenders (which is what i would really do).

Oh, by the way, hashes are great for storing the number of days in a given month:

my %days_in_month = (
   jan => 31,
   feb => 28,     # maybe?
   mar => 31,
   apr => 30,
   may => 31,
   etc ...
);

But you have to account for leap years too ...
