There is very detailed description of codeless (aka nocode) approach, just with rules:

the 2nd sentence of which is:

Updated: 5 more forms added at the bottom: “work days calculation (excluding weekends and holidays)”

There are more trivial/obvious approaches with the use of code.


Assuming you have access to Excel Services, these links may be useful to you:




If proposted codeless approaches don't appropriate in your case, another approach could be to create custom webservice to do this and call it from InfoPath. I used this method in my case.
