Dear Monks,

I have mentioned the below code i tried using Date::Calc module. I have to get the input From date, To date and Hours from the user. I have to distribute the Hours with in the From date and To date i have given. Allocate 8hrs. for each date. Remaining hrs. to be mentioned at last as remainder. I have omit the holidays as mentioned in Date::Calc holidays. Please give me any idea or code.

Thanks in advance. 

#!/usr/bin/perl
 #INPUT : 17 December 2001 to 16 June 2002
use strict;
use Date::Calc qw( :all );

my ($fdate,$tdate,$day,$month,$year,$tday,$tmonth,$tyear,$i,$j,$hour);
my (@start,@stop,@date);

print "Enter the From Date: ";
chomp($fdate = <STDIN>);

print "Enter the To Date: ";
chomp($tdate = <STDIN>);

print "Enter the Total hours: ";
chomp($hour = <STDIN>);

($day,$month,$year)=split(" ", $fdate);
($tday,$tmonth,$tyear)=split(" ", $tdate);

$month = Decode_Month($month);
$tmonth = Decode_Month($tmonth);

if (Date_to_Days($year,$month,$day)  >
      Date_to_Days($tyear,$tmonth,$tday))
      {
          print "\nThe From date should less than To Date\n";
      }
else
    {

  @start = ($year,$month,$day);
  @stop  = ($tyear,$tmonth,$tday);

  $j = Delta_Days(@start,@stop);

  for ( $i = 0; $i <= $j; $i++ )
  {
      @date = Add_Delta_Days(@start,$i);
      printf("%4d/%02d/%02d\n", @date);
  } 
}

Re: How to distribute time using Date::Calc module?

    First you have to create a 3D array @holiday with the dates of the holidays set to 1, like so:
    ### New years day
$holiday[2005][1][1] = 1;

    Fist add the fixed dates like newyearsday, then add the Easter-depending days using Easter_Sunday($year); and calculate the easter-depending days from there as described on Date::Calc.

    Now loop through the days starting at startdate, incement by one and see if the date is not Saturday or Sunday and not a holiday.
