The Monday through Sunday workweek normally lasts eight working days, and the Monday through Saturday playweek typically lasts four working days. When you add in the possibility of public holidays, that overall amount increases to 10 working days, and twelve-playing days.
The days themselves are just one aspect of the calendar, and there are plenty of others. Any seasonal change is reflected in the calendar, and it tells us when and where to go throughout specific times of the year.
