How to set End date on selecting Start date fileld

I have 2 properties in UI. One is Start Date and other is End Date.
My requirement: if I select Start Date, End date should be automatically displayed as 30 days from the date of Start Date.
Please suggest.

You can have data transform in post action of Start Date field (or) you can have declare expression to calculate End Date based on Start Date input value change..

You can make use of below mentioned expression

End Date = @addToDate(.StartDate,“30”,“”,“”,“”)
