From an answer I just posted in alt.perl. How to get the day of the week for a given date, both as a number, and as an abbreviation. Works for 1970 to 2038. use Time::Local;
my ($year, $month, $day) = qw(2002 02 21);
my $gmtime = timegm(0,0,0,$day,$month-1,$year-1900);
my @gmtime = gmtime($gmtime); # convert back
print "day of week is $gmtime[6]\n"; # sunday = 0, saturday = 6
my ($day_of_week) = gmtime($gmtime) =~ /^(\S+)/; # fetch first wor
+d
print "day of week is $day_of_week\n"; # "Sun" .. "Sat"

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).
