I am having a problem with mktime. My payroll week runs from Friday through Thursday and paydate is on Friday 2 weeks later I have the enddate set but am having problems getting the mktime calculate the paydate to print on paychecks. If the payroll week is within the same month as the payday it works fine but when the paydate is in the next month it isn't calcualted right. Thanks for any help you can give. I have been messing with this for days now and can not figure it out. <?php session_start(); //Start Session header("Cache-control: private"); //IE 6 Fix $PayStart = $_SESSION['StartDate']; $PayStart = date('F j, Y', strtotime($PayStart)); $PayDate1 = $_SESSION['EndDate']; $PayDate1 = date("F j, Y", mktime(0, 0, 0, date("m"), date("d")+'14', date("Y")));
