Calculate Shipping Date
This will calculate when a shipment must be made assuming shipments always take
place on the same day(s) of the week.
A1= Requested Arrival Date, B1 = Transit Time, C1 = Weekday (Sunday = 1. Adjust
this number to work with other weekdays such as Monday = 2, Tuesday = 3 etc)
Note: See WORKDAY in your Help files which can be used to calculate arrival time
(this formula is basically the opposite of WORKDAY so far as it used to
calculate the shipping date)
