Question

I need to find date x such that it is n working days prior to date y.

I could use something like date("Y-m-d",$def_date." -5 days");, but in that case it wont take into consideration the weekend or off-date. Let’s assume my working days would be Monday to Saturday, any idea how I can accomplish this?

Thanks for the help guys, but to solve this particular problem I wrote a simple code:

    $sh_padding = 5; //No of working days to count backwards 
    $temp_sh_padding = 1; //A temporary holder
    $end_stamp = strtotime(date("Y-m-d", strtotime($date_format)) . " -1 day"); //The date(timestamp) from which to count backwards
    $start_stamp = $end_stamp; //start from same as end day
    while($temp_sh_padding<$sh_padding)
    {
        $sh_day = date('w',$start_stamp);
        if($sh_day==0){ //Skip if sunday
        }
        else
        {
            $temp_sh_padding++;
        }
        $start_stamp = strtotime(date("Y-m-d",$start_stamp)." -1 day");
    }
    $sh_st_dte = date("Y-m-d",$start_stamp); //The required start day
