This week's challenge was submitted by @NapasornCh - Thanks for your submission!
Everyone has deadlines in business so it's natural to wonder how many working days you have left before time is up!
This week's challenge is to create a macro to calculate the number of business days between two user-selected dates, excluding both weekends and any dates specified by an optional input file. The included input file contains US holidays for 2021, as well as a few vacation days. Your macro should also allow the end-user to select the starting and ending date for the period.
Fun with macros! I often equate interfaces with apps, but this works too!
