Using work-days-only cyclic periods

A work-days-only cyclic period (type W) has only work days. A 5-day work-days-only cyclic period, MYWEEK shows a 5-day period MYWEEK that starts on a Monday.

As you can see, the period does not always start on the same day of the week, because of public holidays. If you want a fixed day of the week, use a rule such as Every Monday in the year, using the free-day rule to avoid free days.
