Hi leonc. The setDate function is used to set the actual date to the value you pass in, not to add days to a given date. When we update dates, I always convert to the date to milliseconds, add the required number of milliseconds based on what I am trying to do and then use that to create the new date. Here is a sample from one of my apps that is calculating a reminder date/time based on some inputs. Hopefully this will help. function setNotificationTime() { var startDateTime = new Date("{!startDate}"); startDateTime = startDateTime.getTime(); var reminderMS = {!Reminder_Minutes} * 60 * 1000; var reminderTime = new Date(startDateTime - reminderMS); return reminderTime; } setNotificationTime(); Something like this should get you a new date 28 days from your issue date. var issueDate = new Date({!Issued_Date#iso}); issueDate = issueDate.getTime(); var dayAddInMs = 28 *24*60*60*1000; var dueDate = new Date(issueDate + dayAddInMs); return dueDate;
