German Phrase
Hast du den Wecker gestellt?
Meaning
The sentence asks whether the listener has set the alarm clock. It uses the perfect tense to refer to a completed action that is relevant to the present moment, such as checking before going to sleep or after waking up.
When to use
Use this question in the evening before bedtime to confirm that the alarm is set, or in the morning when you’re unsure if someone already turned the alarm on. It’s informal, so it’s appropriate with friends, family, or anyone you address with *du*.

Cultural Tip
In German households it’s common to double‑check the alarm before going to bed, especially on workdays. *Wecker* can refer to a traditional bedside clock or the alarm function on a smartphone; both are acceptable. Remember that the informal *du* is used here – with strangers or in a professional setting you would ask, *Haben Sie den Wecker gestellt?*.
