Re: Trouble with Dates

Try

use strict;
use warnings;
use Date::Calc qw( Delta_Days Today Days_in_Month );
my $cnt = 0;

# work out end of current month
my ($y,$m,$d) = Today();
my $mth_end = sprintf "%04d,%02d,%02d",$y,$m,Days_in_Month($y,$m);

while (<DATA>) {
  my @dates = split '\s+', $_;
  $cnt++;
  # fill empty dates with month end
  my @ymd1 = split ',',$dates[0] //= $mth_end;
  my @ymd2 = split ',',$dates[1] //= $mth_end;
  my $diff = Delta_Days(@ymd1, @ymd2);
  print "$dates[0] $dates[1] $diff \n";  
}

print $cnt, "\n";

To get last day of previous month add -1 days to the 1st of the current month. `#perl use strict; use Date::Calc qw( Delta_Days Today Days_in_Month Add_Delta_Days); # add Add_Delta_Days my ($y,$m,$d) = Today(); # Add_Delta_Days #($year,$month,$day) = Add_Delta_Days($year,$month,$day,$Dd); my $prev_mth_end = sprintf "%04d,%02d,%02d", Add_Delta_Days($y,$m,1,-1); print $prev_mth_end;` [download] All the function are documented in Date::Calc. poj	[reply] [d/l]
