Questions & Answers about Mon réveil est réglé pour six heures.

Is "pour six heures" okay here, or should it be "à six heures"?

Both are idiomatic. With this verb, you’ll hear:

• Mon réveil est réglé à six heures (neutral “set at 6 o’clock”).
• Mon réveil est réglé pour six heures (very natural too; “set for 6 o’clock”). “À” is the default preposition for clock time; “pour” emphasizes the target time the alarm is intended for. In practice, both are fine.

Does “pour six heures” ever mean “for six hours” (a duration)?

No. With a clock time like six heures, pour means “for (at) 6 o’clock,” not a duration. “For six hours” (duration) is pendant six heures.

What exactly does réveil mean, and how is it different from alarme?

• réveil = an alarm clock (the device) or the act of waking up (noun).
• alarme = an alarm (signal/alert), and by extension the alarm feature on a phone. For a physical bedside clock: un réveil. On a phone: people say une alarme or le réveil (the alarm function).

Why is it mon réveil and not ma réveil?
