Count the Number of Weekdays between Two Dates

To count the number of weekdays between two dates, you use the Weekday Count function. The earlier input date is inclusive and the later input date is exclusive. For example:

the number of business days in May 2019 = the number of weekdays (inclusive) between 2019-05-01 and 2019-06-01

would calculate the number of business days in May 2019 to be 21. Note that if the first date in the function is after the second date, then the result will be 0.
