How to Say ‘Which day’ in German
An welchen Tag
ahn VEL-khen tahk
[ahn VEL-khen tahk]
💬 Usage Tip: The an comes from denken an "to think of". The verb itself comes at the end of the sentence, so the question opens with an. Same pattern: An wie viele Personen haben Sie gedacht? "How many people did you have in mind?"
