Arbeitstag vs Woche
week
'die Woche' and 'der Arbeitstag' can both have to do with working time, but they refer to different periods of time. 'die Woche' is a period of several days, often Monday to Friday or seven days in total. 'der Arbeitstag' is a single day on which you work, or the working time on that day. Learners may confuse the words when talking about work. As a guide: for a whole period of time, use 'Woche'; for a single day, use 'Arbeitstag'.
Arbeitstag
Herr Richter hat heute einen langen Arbeitstag.
Mr. Richter has a long workday today.
Woche
Diese Woche arbeitet Lisa nur von Montag bis Donnerstag.
This week, Lisa is only working from Monday to Thursday.
