@cmccluskey958 There are always several ways to do these things, but I found that converting the first date to a time value using the JS getTime function, adding two days to that time value, then using the date function on that is an effective way to do it.
export function datePicker1_change(event) {
let firstTime = event.target.value.getTime();
//86400000 milliseconds in a day
let timeTwoDaysHence = firstTime + (2 * 86400000);
let dateTwoDaysHence = new Date(timeTwoDaysHence);
$w('#datePicker2').value = dateTwoDaysHence;
$w('#datePicker2').minDate = dateTwoDaysHence;
}
