I am having trouble setting up my date variable. 
%day2t = qw(
    Friday T  Saturday T-1  Sunday T-2  Monday T-3
    Tuesday T-4  Wednesday T-5  Thursday T-6
);

$tday = $day2t {"$day"};

So I already have some code to determine what day it is and once I know the current day, I set my $tDay variable depending on that.
My next step is to to take this $tDay variable and and subtract that amount from the current date. So, if $tDay contains "t-4", I need to subtract that from today's date.

For example, Today is Monday. So $tDay variable will be set to "T-3". Today's date is 25-Nov-2013. I need to be able to subtract 3 from 25 to get 22 as my final answer. I know how to do this but the part where I am having trouble is how to set 30 or 31 or 28 days for specific months. If current date is 4 and I have to subtract 5 from it, how do I handle that? Please help.
