Calendar Check out date = check in date plus one

I found some similar questions but are older and their solutions didn’t work for me.

I use contact form 7 and date picker.

I have a check-in-date and a check-out-date field.
When a user selects the check-in-date, then when he clicks the check-out-date it should show automatically on the calendar the “check in date plus 1 day”.
What i want is similar to all the booking calendar forms we see out there like booking.com.

The code i use is:

Arrival [date* date-933 date-format:dd/mm/yy min-date:0 placeholder "Check in"]
Departure [date* date-934 date-format:dd/mm/yy min-date:0 placeholder "Check out"]

Any ideas would be much appreciated.
Thank you
