DayCalcHoliday

This adds (or subtracts, if negative) x number of days to a date and tells you the resulting date. You also have the option of limiting the day count to weekdays only, so only 5 days would be used in a week. So for example, if you select 5 for the number of days with WeekdaysOnly checked, and the start date is a Wednesday, the end date will be the following Wednesday. You also have the option of limiting the day count to weekdays and non-holidays only, so, for instance, if Christmas falls in the middle of a week, only 4 days would be used in that week.

This is useful for agreements that say "x number of business days".
