Working day

Extracted from the Wikipedia article Business day.
German-speaking countries
In Germany, Austria and Switzerland, two German words of somewhat different meaning are used to describe business or working days. One is Werktag, a legal term applied to all calendar days except Sundays and public holidays; it includes most Saturdays. Werktage are days on which businesses such as retail shops and institutions such as schools are generally allowed to operate (see also Ladenschlussgesetz). In contrast, Arbeitstag refers to a day on which someone actually works. For most employees, these are Monday to Friday. However, for example, a firefighter might have an Arbeitstag on Sunday even though it is legally not a Werktag.
