CPAN has a search page. You should try it. Date::DayOfWeek I hope this helps ghettofinger	[reply]

An aside: As a Perl hacker, don't you just love it when someone asks for something not too common, and there happens to be a module that fits there needs perfectly, as if the module was written just for them?	[reply]

I can't remember where I read it, but it has been said that if you are going to code more than three or more(?) lines to do something, there is probably a module that will do it. No matter what I am looking for, or how obscure I think my problem is, CPAN never let's me down. Ever. ghettofinger	[reply]

I'd use Date::Calc or one of the other modules on Date from CPAN, but like Old_Gray_Bear said regarding your other post, How do you add dates to a certain user provided date?, your professor isn't likely to accept that solution. - - arden.	[reply]

First of all, kick whoever provided that date in the unmentionables, and tell him or her to give you a four digit year. Then, provided you really, really, don't want to use a CPAN module (which is your best option), then you use Zeller's algorithm. The source I gave has source in Pascal. You'll have to convert it to Perl yourself.	[reply]

To my asnwer to your previous question, add the following: `print $new_time->fullday, "\n";` [download] jdtoronto	[reply] [d/l]

Here is a well-worn snippet from Merlyn `#!/usr/bin/perl #by Merlyn use Time::Local; my ($year, $month, $day) = qw(2004 03 10); 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 word print "day of week is $day_of_week\n"; # "Sun" .. "Sat"` [download] I'm not really a human, but I play one on earth. flash japh	[reply] [d/l]
