See Date::Manip, or any of the other dozen date modules in the CPAN. -- Randal L. Schwartz, Perl hacker	[reply]

You can also look at Is there another way to create a german time string? and adjust the code to your need. If you need to do a lot of date-parsing consider using Date::Manip as merlyn suggested. neophyte	[reply]

Someone offline suggested this to me. Ok, fair enough you don't reinvent the wheel unless you have too or for educational purposes but leaving that aside for the moment is messing with dates one of those things like parsing HTML that you're just better off not trying to do from scratch ? `#!/usr/bin/perl -w use strict; use Time::Local qw( timelocal ); my $year = 2001; my $day = 200; my $year_sec = timelocal(0, 0, 0, 1, 0, $year-1900); my $new_sec = $year_sec + ($day-1) * 60 * 60 *24; print localtime($new_sec)."\n"; my ($theday, $month) = (localtime($new_sec))[3,4]; $month++; print "day = $theday, month = $month\n";` [download]	[reply] [d/l]

e.g. POSIX, which is quite powerfull for this, but sometimes it's also overkill:-) Have a nice day All decision is left to your taste	[reply]
