Looking to the new year (2021), we want to produce a log for our staff showing workdays for the upcoming year. 2 employees follow the US holiday schedule and 1 employee follows the Australian (Victoria) holiday schedule. Produce an Excel file showing the business days with holidays for all 3 employees.
Bonus: How many US and Australian business days are there in 2021?
