excel total days formula including weekends, excluding holidays
 

I need a formula to calculate total days (working days) that excludes
holidays, but includes weekends. The networkdays formula doesn't work since
we work on weekends and have variable days off. I wanted to put the select
days off( some weekdays and some weekends in a holiday range), and have them
subtracted from the start date, end date range if they fall in the range.
