Right now i already do this calculation on sharepoint. but i need to make this calculation on form. Really appreciate your help !

Hi - this is surprisingly hard to do with InfoPath out of the box. However - you can find complex mathematical formulas for this online. Here is one blog post on this - I've not tried this specific one, but give it a shot. I would recommend trying it exactly as written in a test form prior to adding to your actual form: https://www.meartechnology.co.uk/2016/09/16/infopath-calculate-business-days-between-2-dates-including-leap-year/
