Have you tried searching or googling for your terms?
Perl foreach gives me lots of pages with example usage of foreach. Perl strftime gives me lots of pages which point to the POSIX module.
To make it more complete, here are the answers:
foreach my $eachday (@the_days) {
print $eachday; # "eachday" is a bad name
};
use POSIX qw(strftime);
print strftime('%Y ...', localtime)
If you want to do date math, you are best off by using a module like Date::Calc or DateTime, or maybe it's already sufficient to just add 60*60*24 seconds to time, depending on your (untold) needs.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
