Rank 6: Networkdays, workday, today()

Getting the number of days between 2 dates is easy. Just Date1-Date2.

=Workday(start date, number of wordays) will give you the new date added with the "number of workdays".

To find the ranking of a number

=RANK(number, range, 1 for ascending order or 0 for descending order)
