Calculating difference between two date picker fields in number of days in infopath

Question

I am trying to calculate the difference between two date picker fields which should result the value in number of days in infopath.

I tried number(substring(field1, 9, 2)) - number(substring(field2, 9, 2)) but it calculates on the different in dates and does not consider month. If the field one is 5th May 2020 and field 2 is 6th Jun 2020, it still gives the difference as 1.

Can anyone help by suggesting how can this be achieved?

Thank you.

Answer 1

There are two possible solutions to your problem :

1. Using qrules(not free)

2. Use rules, conditions, and the number(), floor(), and substring() functions in formulas to calculate the difference between two date picker controls in InfoPath.
