time required
The amount of time needed to complete a particular task, project, or activity.
Der Zeitaufwand für die Renovierung des Hauses war deutlich höher als geplant.
The time required for renovating the house was significantly higher than planned.
This word is made up of 'Zeit' (time) and 'Aufwand' (effort/expenditure). 'Aufwand' means something like effort or expenditure. So 'Zeitaufwand' is the 'use of time' for a particular activity.
Der Zeitaufwand für die Einarbeitung neuer Mitarbeiter ist nicht zu unterschätzen.
The time required for training new employees should not be underestimated.
'Zeitaufwand' is often described with adjectives such as 'hoch' (high), 'gering' (low), 'enorm' (enormous), or 'erheblich' (considerable). Typical verbs are 'erfordern' (to require), 'bedeuten' (to mean), or to 'einschätzen' (estimate) and 'unterschätzen' (underestimate) the time required.
Wir müssen den Zeitaufwand für die Vorbereitung realistisch einschätzen.
We need to realistically estimate the time required for the preparation.
'Zeitaufwand' is often used in fixed phrases with prepositions, for example 'mit hohem Zeitaufwand' (with a high time investment) or 'ohne großen Zeitaufwand' (without much time required).
Mit geringem Zeitaufwand lässt sich hier viel erreichen.
A lot can be achieved here with little time required.
duration
'die Dauer' and 'der Zeitaufwand' both have to do with time. 'die Dauer' describes how long something lasts from beginning to end, for example a film, a course, or a trip. 'der Zeitaufwand' describes how much time is needed for a task. Here, people often think of work, planning, or effort. Learners may confuse the words because with both you can ask 'Wie lange?' (How long?). If something simply takes place or runs its course, you are more likely to speak of 'die Dauer'. If someone has to invest time, 'Zeitaufwand' fits better.
