I am needing to calculate dates. What I need to accomplish, is according
to
a school calendar, which has weekends, holidays and other specified dates
off
from school, what would be say the 50 day from today excluding the
weekends,
holidays and spring breaks?

Can networkdays or other options within excel help me out?
