Suppose today is my current date I want to add two business days and if the holidays/weekends fall into these days , we append those many holidays and skip the weekends. 11/05/2022 + 2 days = 13/05/2022, if any holidays fall in between these days we move to next workin day ex: 12th is holiday then 14/02/2020 will be my payment date. Ex: if 13/05/2022 is Saturday or Sunday we skip and move to next working day 15/05/2022 is my payment date.
