Questions & Answers about Der Expressversand muss binnen eines Tages erfolgen.
Why is Tages in the genitive case here?
The temporal preposition binnen (within) can take either the genitive or the dative case. In this sentence, it triggers the genitive case, changing the masculine noun phrase ein Tag to eines Tages. Using the genitive with binnen is especially common in written or formal German.
Could I use the dative case with binnen in this sentence instead?
How does binnen differ from innerhalb, which also means "within"?
They are virtually interchangeable when talking about time deadlines, so you could easily say innerhalb eines Tages here. The main difference is that binnen is exclusively temporal (used only for time), whereas innerhalb can be used for both time and physical space (like "inside" a building or area).
Why use erfolgen here instead of a more common word for "happen", like passieren?
Erfolgen is a formal verb that means something takes place as the intended result of a plan, rule, or process. While passieren or geschehen just mean something happens (often spontaneously or accidentally), erfolgen conveys that a necessary step is being carried out. It is the standard, professional choice for business policies like shipping terms.
