What operating system are you using?
---This is a Linux.
What shell do you want to use to run your shell script?
---Bash Shell
In what format will dates be entered?
---Date will be entered as YYYYMMDD whcih i have split into 3 variables.
Where will the dates be found? (Are they provided as variables in your shell script? Are they command-line parameters? Are they typed in in response to prompts? Are they found in known files? ...)
---Dates typed in response to prompts.
In what way do you want dates to be compared? (Are you just trying to determine if they specify the same date? Are you trying to determine the number of days between two dates? If your dates includes hours, minutes, and seconds; are you trying to determine the number of seconds between the two dates?).
---i Want to know the difference in Days and not using Datediff or Date. I just need to use simple if ...else and arithmetics. Also look for number of leap years

cgi::untaint::date
CGI::Untaint::date(3pm) User Contributed Perl Documentation CGI::Untaint::date(3pm)
NAME
CGI::Untaint::date - validate a date
SYNOPSIS
use CGI::Untaint;
my $handler = CGI::Untaint->new($q->Vars);
my $date = $handler->extract(-as_date => 'date');
DESCRIPTION
is_valid
This Input Handler verifies that it is dealing with a reasonable date. Reasonably means anything that Date::Manip thinks is sensible, so
you could use any of (for example):
"December 12, 2001"
"12th December, 2001"
"2001-12-12"
"next Tuesday"
"third Wednesday in March"
See Date::Manip for much more information on what date formats are acceptable.
The resulting date will be a Date::Simple object. Date::Simple for more information on this.
date_format
By default ambiguous dates of the format 08/09/2001 will be treated as UK style (i.e. 8th September rather than 9th August)
If you want to change this, subclass it and override date_format()
WARNING
Date::Manip does not play nicely with taint mode. In order to work around this we locally clobber Date::Manip's 'timezone' code. As we're
only interested in dates rather than times, this shouldn't be much of an issue. If it is, then please let me know!
