Zeitfenster vs Fenster
window
'das Fenster' and 'das Zeitfenster' can both mean a limited period of time in which something is possible or favorable. 'Zeitfenster' is the clear and normal word for this. 'Fenster' on its own can also occur in this sense, but it depends more strongly on context because it can also mean a real window or a computer window. Learners may confuse the words because 'Zeitfenster' contains the word 'Fenster'. If you want to speak clearly about a period of time, 'Zeitfenster' is usually more precise.
Zeitfenster
Das Zeitfenster für die Lieferung liegt morgen zwischen acht und zehn Uhr.
The time window for the delivery is tomorrow between eight and ten o'clock.
Fenster
Vor dem Termin bleibt noch ein kleines Fenster für einen kurzen Anruf.
Before the appointment, there is still a small window for a quick call.
