These holiday lists are linked to Employee master. It is consider when that Employee applies for the leave. The days included in the holiday list is not considered in the leave calculation.

You can write script in Python/JS which can check the Due Date against dates mentioned in Holiday List. It is a simple fetch the list, compare the date and if equal throw error and prevent save or submit.
