Questions & Answers about Die Zustellung ist binnen zwei Werktagen erfolgt.
Why does binnen take the dative plural Werktagen here instead of the genitive?
The preposition binnen can take either the dative or the genitive case. In modern German, the dative is much more common, especially in the plural when there is no article (like here). While the genitive is technically correct, saying binnen zweier Werktage sounds very stiff and bureaucratic.
Could I use innerhalb von instead of binnen in this sentence?
Yes, innerhalb von zwei Werktagen means exactly the same thing. The word binnen is a bit more formal and is heavily used in business, legal, or administrative contexts, making it the perfect choice for a sentence about delivery times.
Why does the verb erfolgen use ist instead of hat for the Perfekt tense?
The verb erfolgen (to occur or to take place) is an intransitive verb that describes an event happening. Because it doesn't take a direct object and describes an occurrence, it builds its past tense with sein rather than haben.
