( #3333=superdoc: print w/ replies, xml ) Need Help??
This afternoon, a co-worker asked me: "how do i get the last day of the month in perl ?"

After clarifying with him that he wanted the "name of the day of the last day of any given month/year", and then having a quick fossick about on CPAN, I threw the following example together using Calendar::Functions:

#!/usr/bin/perl -w use strict; use Calendar::Functions qw(month_days dotw dotw3); while (1) { print "Enter year (yyyy) and month (mm), separated by a space:"; chomp(my $input = <STDIN>); last if !$input; my ($year, $month) = split / /, $input; my $dayname = dotw(dotw3(month_days($month, $year), $month, $year) +); print "The last day of $month/$year will be a $dayname\n"; }

I'm curious to know how others would approach this little task?

(There are a few related Q&A's, - this one in particular - but none are quite the same)

Update: many thanks for all the replies. As always - TIMTOWTDI. However, on this occassion - for pure simplicity - the pony has to go to herkum for his DateTime solution :)

Thanks,
Darren :)
