Another way would be to set it to “use time” and use hidden fields for arrival and departure time to always increase the stay by one. For example 10.07 11:00 – 11.08 13:00 would be 26 hours which are two days.
You asked “Is there a way to change the logic of calculating” and the answer is yes, by changing the code that’s doing the calculation.
