I've solved this in the past with a time dimension table that includes
columns labeling weekends and holidays.  Then I can query for the count of
intervals (for whatever interval size my time dimension uses) in the date
range joined to time_dimension where weekday is true and holiday is false,
and multiply the count by the number of hours in an interval.
