Count the business days a support ticket was open, with a holiday excluded
NETWORKDAYS counts weekdays between two dates on its own, and takes a third argument — a date, or a range of them — to pull out a holiday that would otherwise still count.
Task:
You track turnaround for a small software company's support desk. For each ticket, work out how many business days it was open between the date it was opened and the date it was resolved — weekends don't count, and neither does the company holiday noted in F2, even where it falls on a weekday. Fill in D2, D3 and D4.
The daily challenge is part of Pro
A new exercise every morning, plus every day that came before it — a back catalogue that grows by one a day, whether or not you were here for it.
