Custom Script
Add an HTML Widget BEFORE the Form with this custom script to manage a personalized “dd.mm.yyyy” date format
<script>
function format_date(date) {
let tmp = date.split('.');
date = tmp[2]+'-'+tmp[1]+'-'+tmp[0];
let current_date = new Date(date);
let days = 5; // change with your days
current_date = new Date( current_date.getTime()+(days*24*60*60*1000) );
return ("0" + current_date.getDate()).slice(-2) + "." + ("0" + (current_date.getMonth() + 1)).slice(-2)
+ "." + current_date.getFullYear()
}
</script>
NOTE: If no custom Date Format is forced you can use a single line solution directly into the Set Value field:
new Date( new Date([field id="from"]).getTime()+(5*24*60*60*1000)).toISOString().split('T')[0]
Set Value
Add this rule on Fields Conditions with Value:
=format_date([field id="from"])
