Someone didn't read the help files for the NETWORKDAYS function...

"Syntax: NETWORKDAYS(start_date,end_date,holidays)
.....
.....
Holidays is an optional range of one or more dates to
exclude from the working calendar, such as state and
federal holidays and floating holidays. The list can be
either a range of cells that contains the dates or an
array constant of the serial numbers that represent the
dates."

This formula already excludes weekends from the calculation.

Do you know how I could improve this formula so that it does not include
holidays in the calculation, I can specify the holidays, and I will not
get
an error message if Column K is blank?

Or

Do you know how I can improve this formula so that if Column K is blank I
will not get a #VALUE! message where the calculation should be?

=NETWORKDAYS(K13,L14,Holidays!A1:A29)-1
