I'm connecting to a server thru FTP. Before I do a "cd" to a directory, I need to figure it out which directory. Every mid month the directory change, I need to know the best way of doing it.
below is like a table. The date has to be in between the from and to date, then directory will be set.

  From                           To                          directories
prev_yyyy-12-16 -> curr_yyyy-01-15 = curr_yyyy_01_report (directory)
curr_yyyy-01-16 -> curr_yyyy-02-15 = curr_yyyy_02_report (directory)
curr_yyyy-02-16 -> curr_yyyy-03-15 = curr_yyyy_03_report (directory)
curr_yyyy-03-16 -> curr_yyyy-04-15 = curr_yyyy_04_report (directory)
curr_yyyy-04-16 -> curr_yyyy-05-15 = curr_yyyy_05_report (directory)
curr_yyyy-05-16 -> curr_yyyy-06-15 = curr_yyyy_06_report (directory)
curr_yyyy-06-16 -> curr_yyyy-07-15 = curr_yyyy_07_report (directory)
curr_yyyy-07-16 -> curr_yyyy-08-15 = curr_yyyy_08_report (directory)
curr_yyyy-08-16 -> curr_yyyy-09-15 = curr_yyyy_09_report (directory)
curr_yyyy-09-16 -> curr_yyyy-10-15 = curr_yyyy_10_report (directory)
curr_yyyy-10-16 -> curr_yyyy-11-15 = curr_yyyy_11_report (directory)
curr_yyyy-11-16 -> curr_yyyy-12-15 = curr_yyyy_12_report (directory)

I'm assuming prev_yyyy and curr_yyyy should be replaced by the previous or current 4-digit year.  Let me know if that isn't the case.

my @now = localtime();
$now[4]++;
$now[5]+=1900;
 
if($now[3] >= 16) {
	$now[4]++;
	if($now[4]>12) {
		$now[5]++;
		$now[4]=0;
	}
}
my $directory = sprintf("%4d_%02d_report", $now[5], $now[4]);
print "directory=$directory\n";

if date is between 2008-12-16 -> 2009-01-15
then dir should = 2009_01_report

the way it is now, it end up with 2009_00_report

on the directory name, instead of 2009_00_report
I need to change it to 2009_00.report, with the dot.
when I do that, it mess up the
my $directory = sprintf("%4d_%02d.report", $now[5], $now[4]);

#To simulate other dates:
#  Add to your script:  use Time::Local;
#  pass timelocal(sec,min,hour,day,month-1,year-1900) to localtime
#eg: my @now = localtime(timelocal(0, 0, 0, 18, 11, 108)); #18-dec-2008
my @now = localtime();
$now[4]++;
$now[5]+=1900;
 
if($now[3] >= 16) {
        $now[4]++;
        if($now[4]>12) {
                $now[5]++;
                $now[4]=1;
        }
}
my $directory = sprintf("%4d_%02d.report", $now[5], $now[4]);
print "directory=$directory\n";

I have a case where the directory is  
%4d_AP_%02d_abc:[DATA.%4d_AP_%02d.DAILY_REPORTS]

inside the bracket, the %4d becomes "   0" and %02d becomes "00"

In the sprintf, you need to provide the substitution values in the order they are listed.

With your new directory, you'll need to provide the year and month twice each.
$directory = sprintf("%4d_AP_%02d_abc:[DATA.%4d_AP_%02d.DAILY_REPORTS]", $now[5], $now[4], $now[5], $now[4]);
